There are several species of carpet beetles found throughout the United States. The more common species include the varied carpet beetle, the common carpet beetle and the furniture carpet beetle. Distant relatives include the hide and odd beetle. These beetles are amongst the most common pests found in homes. This is true because they usually don’t develop large populations which are easy to find. You’re more likely to find one or two every now and then but since they live in hidden areas “out of sight”, carpet beetles tend to be “out of sight, out of mind”. Unfortunately, their populations will readily grow and if left to feed as they wish, they can cause significant damage.

Carpet beetles exist throughout the entire United States. They mostly live outside feeding on many types of plants. During the summer months, when populations are most active, they’ll find their way into homes through windows and open doors. Carpet beetles can fly so it is easy for them to get inside. It is not known why they seem ready to get into our homes, but its suspected there are certain scents or odors which lure them.

Like the common house fly, carpet beetles seem to know when doors or windows are open. If they enter at this time, they are usually looking for a place to lay eggs. Adults which have fed during the summer months mate and females will spend their time laying eggs. All types of carpet beetles resemble lady bugs but are smaller. in general, they’re about 1/3 to 1/2 the size of a lady bug.

VARIED CARPET BEETLEThe coloration of carpet beetles will vary. Like snow flakes, its not likely you’d find similar patterns on any two specimens unless they’re gathered from the same home. Only then is it likely they came from the same DNA.

Carpet beetle color will range from light to dark. You may find some with different colored spots on their wings; others will be solid in color. Although their look and coloration vary, a trained eye can properly identify them.

Once inside the home, female carpet beetle will look for a place to lay eggs. She will lay 50 to 100 eggs on surfaces that she expects will provide good food for hatching larva. In fact the larvae are the stage which cause the damage. They eat just about anything. Common food includes carpet, furniture, clothing, drapery, pet or human hair, antiques, and just about anything made with or has natural material on it. For example, most synthetic carpets have some natural content mixed in during the manufacturing process and can be food for carpet beetle larvae.

CARPET BEETLE LARVACarpet beetles ability to find food enables them to live on many items found in the home. Most people will find “pockets” of adults or larva. This is common on the underside of furniture, along the baseboard where carpet meets molding, under area rugs, or in closets. So don’t be surprised if you notice them in one small area but can’t find them elsewhere. But 3-6 months later, they turn up in another area of the home and are no longer active where you first saw them. This is classic carpet beetle behavior and very much “normal”.

Carpet beetles generally lay eggs just once a year but once established in the home, they may produce them more frequently. Adults live 2-4 years so they are capable of laying hundreds of eggs during their life span.



You may find a carpet beetle pocket nesting in a piece of furniture in the living room and then another group upstairs in your closet. These pockets could have been formed by different beetles coming in the home or a single egg laying female could have left the furniture downstairs and laid eggs in the closet. Because of this random behavior, its very much smart and necessary to treat all carpeting, furniture, etc. to insure some are avoiding the treatment. Many people will make the mistake of not treating certain areas or maybe ignoring their furniture. This is not recommended.



The most frustrating type of carpet beetle infestation is one which is thought to be in a closet. In these scenarios, a piece of clothing is found which has a hole or two chewed in it and are immediately diagnosed as having been eaten by clothes moths. In fact its much more likely the insect causing the damage is a carpet beetle.

Moth infestations are easy to identify because you will see adult moths flying around the clothing. You will readily find adults, pupa casing or cocoons and larva in your clothing because they tend to stay where they are feeding.

But carpet beetles are very different. Once the larva feeds, they will generally move elsewhere to pupate. They won’t move far, but they usually won’t stay in the clothes and therefore its sometimes hard to find anything that might be causing the damage. When this happens, its a sure sign you have carpet beetles.



Controlling carpet beetle infestations can be difficult. This is true for several reasons.

First, they’re likely to be active in small areas but there are usually several such areas throughout the home. So unless you treat everything, its quite possible to miss a key area.

Second, they tend to be active in hidden areas. Unlike roaches, ants or flying pests, carpet beetles feed and nest out of sight. Though most pests learn to hide out of sight, they tend to feed where we are likely to see them so we know the pest, where its active, where we need to treat, etc. Carpet beetle infestations are more likely to be discovered because of the damage they do – not because large populations are being found.

Third, the cycle of the carpet beetle enables them to have a built in defense mechanism against treatments. Although larva and adults are easily killed, eggs and pupa are not. When you treat, it is likely you will kill adults and larva which are active. However, eggs and pupa can remain dormant and developing for many months. This enables them to avoid the residual treatment because it will have worn down and weakened to such a degree that they can get re-established.

To stop this from happening, its important to treat at least once a month for 3 months straight if not 4-5 times.

Here are some more guidelines that apply to carpet beetle problems to help insure a successful treatment program.

1) Be sure to treat all carpets. Though you may have synthetic carpeting throughout the home, don’t ignore it. Carpet beetles will readily target any fiber and you don’t want to miss even just one pocket of activity.

2) Don’t ignore area rugs. These are readily infested since they’re more likely to have natural fibers. Be sure to turn the edges up and to treat 2 feet “in” under the bottom side if not the entire bottom. Larva will feel right at home under area rugs and if you see some on top, there are probably more on the bottom.

3) Treat all fabric woven furniture. Be sure to turn furniture upside down and get their bottoms. If the light fabric on the bottom is hanging low or is torn, spray inside the piece. Larva and adults will readily seek such places.

4) Don’t skimp on chemical applications. Because carpet beetles tend to be deep in carpeting, its important to have good “penetration”. If you disperse the amount of mixed material over too large of an area, it may not get down deep enough where it needs to be. This will render the whole treatment ineffective.

5) Understand it will take time! Since eggs and pupa are impervious to the chemical treatment, they will continue to live. After 30-60 days, they may hatch and live as if you never treated if the original chemical has broken down. In fact this happens quite a bit which is why you should expect to spray 3-4 times for most any carpet beetle infestation. Now once under control, you may want to treat once every 3-4 months to make sure they don’t come back. More about these options will detailed below.

6) Clothing where infestations have been discovered needs to be inspected. Though you can spend a lot of money laundering all your clothes, its usually not needed. Take a vacuum to all your clothes for a quick and effective way to remove adults, larva, eggs or pupa. Be sure to throw away badly infested pieces.

7) Do a thorough vacuuming of the home before treating. This helps because it will remove some of the beetles as well as get them lifted “up” so they’re more vulnerable to the treatment. Basically the spray will have more of an impact if the beetles are stirred up.

The above guidelines are general and apply to most situations. If you have a unique problem which may need some further preparation, be sure to call for suggestions.



Now that you’ve vacuumed and allowed for access to furniture and closets, you are ready to treat.

SOLO BUGSPRAY SPRAYERTreatments will generally be done with one of our SPRAYERS. Be sure to use one which has a nozzle that sprays in a flat fan. This means it comes out much like the way a paint brush applies paint – in a pattern which is uniform and constant. Nozzles which spray inconsistently will not allow the product to be uniformly distributed over surfaces. This will lead to areas not properly treated which will let the carpet beetles live. Our private label sprayer comes with the exact tip needed to do the job correctly so before you do anything, make sure you have a good sprayer for the job or get one of ours.





Watch this short video to see what a “fan pattern” looks like.


D-FENSE SCThere are several chemicals available for carpet beetles but based on our results, one of the best is D-FENSE SC. This material is odorless, will easily last a month and will knock the population down quicker. It uses Deltamethrin for the active which is very effective for a wide range of household pests. Mix 1 oz per gallon of water and expect to treat once a month for at least 3 months using 1 gallon of mixed material for every 800 sq/ft of area you spray.

D-Fense SC




Now since there can be eggs throughout the infested area, it’s important to think “big” when spraying. This way you insure you get all stages sprayed – including any that might be hiding.


Since carpet beetle eggs can lay dormant for 3-6 months, it may be necessary to treat every month for 4-6 months to get complete control. Every case is different.

So in general, 3-4 treatments will resolve about 50-75% of the homes treated for carpet beetles. But for the other 25%, 4-6 treatments are needed. This is why some pest control companies will charge $1000.00 and up to do a job! Its very likely they will have to come back to the home several times and since there is no way to know how long any one population of carpet beetles will need treatments, they must insure they’re properly covered for a worse case scenario.



Nylar IGRSo to help insure you don’t miss any developing eggs, add INSECT GROWTH REGULATOR to your D-Fense tank mix and use it at the same time. Growth regulators are basically a juvenile hormone (protein) which is labeled for many pests like roaches, ants, etc. And when egg or larvae are exposed to this protein, they’re not able to properly develop into adults. This can help big time by ending the life cycle of the existing population.

Add 1 oz of IGR along with the 1 of of D-Fense in a gallon of water for every 800 sq/ft of area to spray and you’ll be adding a big “helper” to the treatment.

Nylar IGR




Now remember, the D-Fense will only last about a month so by adding a growth regulator to the tank mix, you can  enhance your treatment and get longer protection without doing a lot of extra work.

Growth Regulator lasts 2-3 months and helps to stop the likelihood of re-infestations by controlling the young stages. And since there are so many locations for eggs to hide, every tool you’re able to add to your arsenal can make the difference between success and failure.



Deltamethrin DustAnother “tool” that can help is DELTAMETHRIN DUST. Since liquid sprays are not well suited for all the areas carpet beetles may be active, the use of a dust can help. Remember, eggs and adults will many times be “up and inside” furniture hiding just below seat cushions and very much out of sight. How do you treat these areas without soaking the furniture? Well, you can’t.

Better suited for the job is either a dust or aerosol. For the underside of furniture, nothing beats a light dusting with Deltamethrin Dust. This product is light and a lot like baby powder so it permeate up and around the hidden area. And since treatments will last 6 months, you generally only have to treat once and you’re done.

Deltamethrin Dust




CrusaderUse a CRUSADER HAND DUSTER to apply the dust up and into the spaces and voids where carpet beetle love to hide. The duster is easy to use and will make treating easy.





Dusting is also ideal for getting coverage under baseboard molding. There is a big space in this area where carpets “tuck” under the wood. Carpet beetles love this location and regular liquid spray won’t get into the void adequately. But dusting with Delta Dust will take care of it for good, with just one treatment.



Bedlam PlusIf by chance you have a small area to treat, like a single piece of furniture, area rug, hardwood or tiled floors, a closet or an automobile, go with BEDLAM PLUS. It’s practically odorless and contains both an adulticide and an egg killer. It’s more costly to use compared to the liquid sprays but because it’s conveniently packed in one can, Bedlam is ideal for small jobs and for flooring where spraying a liquid is not cosmetically possible (like hardwood or tiled floors).

Bedlam Plus




Like the D-Fense, you’ll need to use it once a month for 2-3 months for complete control. One can will treat up to 1500 sq/ft and it can be used on mattresses, beds, etc. making it ideal for hard to treat sensitive areas in the home.



Dermestid MonitorsLastly, we have several carpet beetle traps which should be used to help control and monitor the problem.

Keep in mind the use of traps should not be considered a “solve all” mechanism. But they should be deployed with most carpet beetle control programs. They can help by identifying problem areas that may have been missed or they can help by alerting you to an outbreak of hatching eggs and/or pupae.

The first trap is our DERMESTID MONITOR. These “half dollar” sized discs are full of a food lure carpet beetle larvae like to eat. These monitors will attract larvae from several feet away. Set them in sensitive areas where they can serve as an early warning system to missed areas, newly hatched larvae, etc. Dermestid Monitors are NOT traps so any larvae you see foraging around, on or inside the discs need to be removed by hand, vacuum or piece of scotch tape. But since carpet beetle larvae are slow moving, caterpillar like creatures, they’re easy to remove and collect (and they don’t bite).

Dermestid Monitors




Varied Carpet Beetle TrapFor adult beetles, we have two kinds of CARPET BEETLE TRAPS available. The Hanging style can be set out around windows or large open areas where adults have been seen flying. Low profile traps should be deployed on furniture, carpets, rugs and under furniture where space is limited and tight.

Keep in mind that unlike the Dermestid Monitors which will attract a wide range of larvae, the pheromone traps are specific to either VARIED CARPET BEETLE or BLACK CARPET BEETLE species.

How can you tell which carpet beetle specie is active? That’s easy. Varied Carpet beetles will be multi colored. Typically they’re light with different colores mixed in. These other colors will be odd shaped and each beetle will look unique and different.

Varied Carpet Beetle Trap



Black carpet beetles will be solid in color. Typically they’re dark brown to black but can be dark gray too. The key to tell its a black carpet beetle is that the color will be consistent on its shell all the way around with no variation or odd discolorations randomly appearing.

Black Carpet Beetle Trap




Either trap will remain active for 2-3 months and should be set throughout the home. You can “mix and match” traps to take advantage of quantity discounts so if you have a mixed infestation, get some of both.

Also, its important to understand that carpet beetles will usually get “in the mood” 2-4 times a year so in general, there will be one month per quarter where the adult beetles should be attracted to the traps you set out. In other words, they may not collect beetles for 1-2 months and then all of sudden, several get caught. This is normal. Just be sure to inspect them 1-2 a month and replace them after 3 months if you suspect the problem is lingering. But for some, keeping fresh traps in the home year round is a good practice so any new outbreaks are easy to spot and control before damage is done.

What categorizes an infestation? I had 2 new blouses in bags between my closet and my dresser. A turtleneck was purchased on clearance and was out of season. I kept forgetting to put it in storage. The other blouse was the wrong size, needing to be exchanged. It had been there for maybe 2 weeks. When I was deep cleaning, I found a beetle on the turtleneck with one larva. I later saw something that looked like a fiber on the other blouse but when I went to remove it, I swear that it jumped. I assume that, too, was a larva. I have since cleaned the floor of my closet. I found 2 things that could be a molting and one dead beetle. I have moved everything that was on shelves or the floor into the trash or the hot 105 Kansas heat to be cleaned before returning to the treated closet (shoes and blankets). We are treating the carpets today. I assume, from reading this article, that there are more in our home. We are deep cleaning everything this week. We are steaming and treating the carpets. But I am not sure what classifies an infestation.
Thank you, Jeanne

Hi! We appear to have a large carpet beetle infestation (varied)? We originally thought we had clothes moths infestation when we would see random small moths fly out of our closet and saw silken casings like lint on our clothes and when rubbed off noticed holes. After doing a lot of research we realize we have carpet beetles too and a lot. They are now in the larvae phase and all over the house! We originally found the larvae in the carpet under our bed where are cats primarily stay. After cleaning, we have found them in clothes drawers, on books, on socks, on clothes hanging in closets, on shelves. All over my daughters stuffed animals in all rooms of the house. Crawling on wooden toys, in the broom closet, upstairs on towels in guest closet, on guest bed and carpet, under wool and silk rug in living room, under all of the couches as well as between cushions upstairs and downstairs….everywhere. I thought the larvae was clothes moths since we had seen moths, but they are are tiny and fatter… We have seen many, some brown and hairy, some small and cream, some lighter brown. Are all these varied carpet beetle larvae in different stages or could we have other kinds as well? The reason I’m sure that we have the varied ones is I remember in early spring I saw the adult beetles on the window sills and my daughter loved catching them and playing with them thinking they were tiny lady bugs and harmless. I had no idea they would ever lead to this disaster as I have never heard of carpet beetles before. Please give us some advice. Have read your page and it seems we need everything for this infestation!! I am totally overwhelmed!! Half of our house is wood floor and other half carpet. We have a 3 year old and 2 indoor cats. We need something safe for them and are willing to do whatever it takes! Thank you so much! -Liz

We moved to a new House 4 years ago. I remember seeing some little bugs once in a while but because I was most of the time out of home, I didn’t pay a lot of attention. I thought they were lady bugs! … Now I’m a stay home mom and I noticed a lot of bugs (now I know is larvae!) mainly in our carpet, everywhere. We live in a town home and they are in all levels of the house. I see them close to the walls, hiding close to the base of furniture, in the wood floor and inside our kitchen cabinets and sometimes walls. I feel so frustrated! My baby is starting to crawl but I don’t want her to move anywhere! Every time I see one of these I want to cry! We had our carpet professionally washed and they still appear. We bought a Dyson vacuum and they are still everywhere. I noticed that they haven’t been in our clothes. I have found several of them in the stairs lately. I’m so stressed about them that I developed the knack to see them :(

I’m thinking even in changing the carpet for the whole house (would this help?)… Please give me some advise of what can I do. I don’t know what to do and I don’t want to get ripped off if I hire and exterminator ( I’m in Seattle).

My carpet beetle problem started in September. Since then I had to throw away my living room set because it was a nest of larvae inside each sofa. I cleaned my house thoroughly, I threw away clothes and bags where the beetles were present. So instead of me seeing lots of beetles at one time like I use to, I may see one or two around the house now. It’s so frustrating!! I did as much as I can. Why are they still present in my home? Where else can these annoying bugs be hiding out? I would have to do the job myself because hiring a exterminator can be costly.

DESPERATE 4 help/understanding/relating to a nightmare my imagination cannot fathom! “INFESTED” doesn’t give enough credit 2 what is going on in my home. Carpet beetle larvae everywhere! I truly mean “everywhere”. I have contracted with a reputable extermination company. I feel I shouldn’t be finding at least 7+ larvae alive a day.

Nobody understands what I am going through and was even disbelieving until recently because my house looks clean and nobody see’s bugs running across my floor. I am disheartened and need someone to ask questions that understands carpet beetles. I am only now really finding the extent of problem. I am horrified with the # of cast skins I find everyday. I have spent thousands already and I don’t know where to turn. Please advise!

I am planning on having my house tented for drywood termites soon. I am sure after reading the above article that I also have carpet beetles. I have not seen evidence of them but have had a lot of my cotton clothes ruined with small clothes. It disheartens me to read they thrive where there are pets —I have 4 dogs and 5 cats!!

Anyway, can you tell me if the gas they use in tenting (Vikane) also kills carpet beetles?

I saw three beetles crawling on my favorite old blanket and immediately threw it away. For the past month, I would see one or two in my room, as that is the ONLY room that has carpeting, but have spotted three or four in roundabout places. How do I treat this, considering the rest of my place has hardwood floors or tile?

I think I just discovered carpet beetles in my closet. I have been in the house for three years and kept a laundry bag of clothes that needed alterations in the closet for the last three years. It was right below my hanging clothes. I am about to move, so I was pulling the bag out to see what I could keep. The top two items were brand new and seemed fine with no damage but the third piece was a sweater that was completely eaten away. I looked more closely a the bag and could see casings throughout. I rushed to get a trash bag, wrap it up and put it outside. I also spayed a couple shots of lysol into the closet and on the bag before I handled it and put it into the trash bag. Did this help? I have not, in 3 years, seen any damage to my hanging cloths. But I want to know how to handle the closet to keep this thing from spreading.

I can’t even say that I have seen any adults in the house while I have been here. Before I pull anything out I want to know the best course of action. Should I be worried about my hanging clothes?

@Tech Support:

So if I understand correctly, you are suggesting spraying and treating the area before laundering or dry cleaning the clothes in the closet? If at all?

I know I have a carpet beetle infestation as I have seen casings, larvae, and now beetles near windows and doors as well as small holes in some of our clothes. We rent our home so I don’t have too many options (knowing my landlord she’ll say it’s my fault and I must take care of it). We are planning on moving in a few months and I was wondering how I can make sure I don’t pack this beetle and move it with us. What would you recommend? Thanks, Jayne

Hi. We recently discovered carpet beetle larva in our closet. We just moved from an apartment that was infested with them and I was hoping we wouldn’t bring the problem to our new home. Unfortunately, it appears we did. Having dealt with this issue for the past couple of years (my landlord never took the appropriate measures to deal with the problem), I am sick over the fact they’re here. I thought I did all that I could to prevent any from “hitching a ride”. I’ve only seen the two larva, but knowing the nature of this pest, I’m assuming there are more somewhere. Needless to say, I’m frustrated and do not want to deal with this anymore. Obviously, I want to deal with the situation in the most effective and speedy way possible so it doesn’t reach the severity it did at our apartment. However, I need to do so in a safe way as I have 3 very young children. Are there any products I should not use because of the kids? Thank you for you advice.

Hi there,

We have all wooden floors except for some area carpets. I found carpet beetles/larvae on a woolen area carpet and some larvae in clothes in boxes on the floor all in the kids room and also some larvae in the connecting room in some of my woolen clothes 2 weeks ago (no damage was yet done). 2-3 days later I decided to throw away the carpet. After careful cleaning (clothes/fabrics/toys through hot washes and in plastic bags) and vacuuming I haven’t seen any since Sunday (4 days ago).

My question is whether or not I need to seriously worry about areas where I didn’t see them? I didn’t see a beetle or larvae on the two area carpets in the lounge room or in the hallway. (I only found a few adults by the window in the lounge room). I have been vacuuming these carpets regardless. Do I still need to treat them?

And the second question is how long do I need to go without seeing a larvae to take a deep breath out and know that the problem is behind me?

Your informed opinion would be GREATLY appreciated.

Thank you.

Thank you for the extremely informative article. I plan to purchase the products you recommended and begin treating my home immediately. We’re now going on a SIX YEAR carpet beetle struggle that seems to disappear and then return in cars and homes that were not previously infested. We’ve never treated with pesticides, but I’m now at the breaking point where I can’t deal with another infestation.

You were very clear about the treatment plan so I don’t have any questions about that. However, I do have a couple of burning questions that I really hope you can answer out of the kindness of your heart. It’s necessary for me to go through the history of our problem step by step, so please bear with me.

It started in 2009 when we lived in Ohio and the floors of my husband’s car became heavily infested with carpet beetles. He always left the windows down and had spilled coffee and food on the floors more than once. He also isn’t the cleanest person, so he didn’t vacuum his car very frequently. To top it all off, it rained in the car once or twice when he left the window down, so there were definitely things growing in that carpet to attract nesting beetles and feed them.

I started noticing them in the house after a few months. They were only in the kitchen on the windows though–I never saw them anywhere else. At the end of the summer 2009 we got rid of that car and moved to Washington, D.C.

We didn’t see the beetles again until the Spring of 2010, when I started noticing tons of larvae in MY car. While not as disgusting as my husband’s car, we do have three children, so there were frequently crumbs and other debris on the floor. I vacuumed every week. Every time I would think I had vacuumed all of the larvae, more would appear by the end of the week. By the end of the summer I started seeing multiple adults.

They completely disappeared from the car in the fall and winter and then returned in the Spring of 2011. Although I never saw them in our house, this cycle continued for another year–disappearing in the winter and then returning in the Spring of 2012, when they became completely out of control. Larvae were in the trunk, under the seats, everywhere, adult beetles were flying around while I was driving. I only got relief when I vacuumed once a week, and they always returned by the end of the week. My mother tried to persuade me to spray the car but I didn’t want to use pesticides in my car because I had just had a new baby and was thinking of getting rid of the car anyway and purchasing another one.

In Summer of 2012 when the beetles became absolutely unbearable, the car actually died. We got a new car and we moved that summer to a new place. We were so paranoid about taking the beetles with us that we threw out most of the items that were in the old car and quarantined, washed and inspected any clothes or items that we retrieved and saved from the trunk of the car.

We thought they were finally gone. We didn’t see any beetles or larvae in the new house or new car from the Summer of 2012 to the Spring of 2013. I was still walking on eggshells though–every time I saw a black speck anywhere or something flying I freaked out–but it was always a false alarm.

It is now June 2013, and two weeks ago, a saw an adult black carpet beetle at the bottom of a cup in our living room. About a week later, I was playing on the floor with my baby, I moved one of his toys and saw another adult black carpet beetle crawling near our area rug. A few days later, I upstairs in my daughter’s room and saw two carpet beetles crawling near her window/bed. One was brown/black striped, the other was totally black. This week, I saw a brown and black carpet beetle in my bathroom, and then a larvae near my son’s window. Today, I found about 5 or 6 larvae in the unused jaccuzzi bathtub and bathroom window in my bedroom. I am devastated, but I now know that it’s time to take action with pesticides.

So these are my questions:

1. What are the chances that we had a new infestation each time? Is this the same population of carpet beetles from Ohio–is it really possible that we brought the carpet beetles with us from Ohio to DC, and when we moved twice and changed cars? Do they hibernate and then reappear in the spring or summer? Also, why am I now seeing two different species of carpet beetles?

2. Up until now, we only saw the brown/black striped beetle and black larvae, but now we’re seeing adult black colored beetles as well. Does this mean that another species came in from outside, or is it possible for them to evolve?

3. How do I keep them out of the new car? Should I do a preventative treatment of the carpets? I can deal with them in the house until I treat and get them under control, but I am really afraid of them migrating to the car on a piece of clothing or something. It was a nightmare to have them in my car for two years and I don’t want to go down that road again.

4. If I treat them and get rid of them completely–let’s say I don’t see any for the next 5 years–what are the chances of one coming into our house or car again if we’re careful with vacuuming and keeping the windows and doors closed?

I’m finally recognizing that I need to treat them with pesticide and I am looking forward to doing so with products purchased at your store. I hope it works and hope I can save someone else from the nightmare that we’ve experienced over the past 6 years. I’m looking forward to hearing from you Bugspray!!

Thank you!!!! This has been invaluable. I hope to be writing you back in six months with a success story. @Tech Support:

One more question. Are you recommending that I pre-treat the car before I even see any beetles in there? @Tech Support:

Are all the treatments you’ve stated above safe for humans and pets?

Hi, if I wanted to treat an entire house with just the essentials at a good cost what should I buy and how much would they be?

Thank you! Also. would larder beetle control be almost the exact same as carpet beetle control with the same products as well?

We have been finding carpet beetles around our windows for the last few months. We didn’t know what they were. We would find an occasional larva in a kitchen cabinet in empty dishes or in drawers. We thought they were weevils but thought it was strange that they were not in food or around food. Now we know they are carpet beetle larva. I have read multiple websites on how to treat for these little buggers and I am glad I came across your website since you answer questions.

The labels on the different pesticide concentrates say that the pesticides should not be sprayed on the entire surface of the carpets or on areas where people will be in contact on a regular or prolonged basis, just in the cracks and crevices and along baseboards. Your instructions say to spray the carpet, drapes, and upholstered furniture. I really want to get rid of these bugs. Is it safe to spray the pesticides on the entire surface area of the carpets and furniture? How about box springs and mattresses? I have wall to wall carpeting on our upper level and area rugs on our main level. I also have children and 1 outdoor dog.

My house is large and we have seven children who are all home for the summer. Plus we have to live life! Nearly impossible to have the entire house ready for 1 big clean/spray day. My plan is to move from room to room in my home within a 2-3 week period, cleaning, vacuuming, and spraying as I go. I plan on keeping a calendar of when each room was treated, so I can repeat each room within a month’s time of when it was originally treated. I will continue to treat over a 4-6 month period as you suggest. Is there anything wrong with this plan? Or am I just going to be chasing the bugs from room to room and wasting a lot of time because I don’t treat all at once? Thanks!

How bad is my situation as it seems really bad to me? I do not see any adult beetles but find 2-4 larvae everyday on the baseboard. My daughter calls me the Bug Hunter as this is exactly what I do the minute I get into the house, pull out a flashlight and start inspecting all baseboards on all 3 floors. The basement is carpeted and I haven’t seen any in the carpet and the corners that I pull up but I am so tired of seeing the larvae everyday. I vacuum 3-4 times a week on hands and knees, all the baseboards. I have a toddler and a young baby so very hesitant to use chemicals – although I know the ones you listed are safe.

What would be my best course of action and how long does it take to get rid of them? I feel like I have no time for my family as I am constantly cleaning and vacuuming. It’s takes me at least 3 hours just to vacuum and being a working mom, I would like to spend time with my kids after a long day at work rather than chase these pests – trying to ensure my kids have a clean floor to play on. Thanks.

Hi there,

I have some questions as I get ready to treat my home for carpet beetles. I see larvae daily but I can only recall once seeing an adult.

1. I have hardwood floors throughout the entire house, there are three area rugs (living room, dining room, and one of the three bedrooms) but no wall to wall carpeting including in the closets. I saw that in response to someone else asking about treating hardwood, you mentioned it doesn’t need much treatment. One of the bedrooms has newer hardwood that has crevices between the boards as part of the design. I’ve seen most of the larvae in this room in the crevices, several feet away from the wall (there is no area rug in this room, by the way). I’m wondering how to go about treating the floor? Since I’ve seen the larvae in the middle of the room, is it correct to assume that I need to treat the whole floor?

2. Should I treat the mattress? I’ve never seen any larvae or casings in the bed.

3. How should I treat the closets and the bureaus? I’ve seen larvae in both of these areas. Should I empty out all the clothing, wash/dry clean all the clothing, treat the closet/bureau, and then put all the clothing back? What products would you recommend for treating a closet and the insides of a bureau?

4. I think somewhere it was mentioned that after treating, one should not further clean (i.e. shampoo the carpets) because it would cancel out the treatment. What about treating a bathroom? I’ve seen multiple larvae in the bathroom roaming on the grout where the wall meets the floor. Does the humidity in a bathroom affect the treatment? Should I treat the bathroom more frequently?

Any and all advice you have to offer is welcome! Thank you!

Hi. I have been reading all the posts as well as the information you have on here, so thank you for the information!! My question is in regards to a rental house that I do not yet live in, but had planned on living in. I found 1 or 2 larva on the walls of each of the rooms in the rental house. I had never seen anything like this before, so I googled it (after taking a picture for comparison before squishing it and discarding of it) and quickly realized it was in fact carpet beetles.

I then notified my pest control company who regularly sprays my home I live in now and they sprayed all the rooms, carpets, closets, kitchen cabinets and drawers, air vents and even some on the walls. The pest control man said the chemicals he used are what he uses for cases of fleas, bed bugs and carpet beetles. I have severe hesitations about moving into a place knowing it has a current infestation, and I don’t have one currently at my present location. Would you have hesitations about moving in? Also, what are the chances that I have carried some of these horrible pests from the rental house into my car or current home from just walking on the carpets there???

Thank you for your help!!!

I have read your article and most of the comments. My only question is what would you recommend for my home? My husband and I just bought a home in January of this year (2014). At the end of February we had to replace the dishwasher that came in the home and shortly after that we started seeing some little black beetles. Initially I thought nothing of it and assumed that using the heat after months of a vacant home caused some bug eggs to hatch, after killing a few of them (and other insects like spiders and what not) I decided to purchase some pesticide and spray the house (Ortho home defense). It worked great except for what I found out they are carpet beetles. When the home defense didn’t work I started doing some research and purchased a pesticide that said it killed carpet beetles. I deep cleaned my home then sprayed every door, window, baseboard, and carpeted area. I didn’t do enough research to know that it didn’t kill eggs. It is a treatment that keeps killing for up to 3 months after use so now I find some dead beetles along the floors however I mainly find adult beetles in my kitchen near the sink and window, all over the counter and window sill. I have a dog and a toddler so I have been hesitant on bombs, which I now know will do nothing to them anyways. After speaking with my neighbor who told me she has a problem as well that started about two years ago, then another neighbor told me the previous tenants (the only other owners of the home) were not very clean people and had a rodent problem in the past, and from my understanding carpet beetles like to live in nests and will live off rodents, perhaps this is where the problem started- not too sure. Either way, I think I am dealing with a bigger problem than even I initially thought. I am not seeing any larvae, that I know of, just adult carpet beetles. I have been vacuuming my home daily (some times twice a day or more), where the baseboards and carpet meet, in every crack and crevice I can fit my vacuum hose under. I have spoke with a few exterminators, some say the problems could be coming from attic or crawl space, others say impossible, should I check the crawl space and the attic? Which products should I use? How should I treat my home?
Thank you.

I forgot to mention that we moved the new dishwasher out, found a good amount of beetles under the dishwasher so we sprayed under there and caulked a hole that was leading to the outside, and put the dishwasher back, now I am finding them under my sink again, dead however since I also sprayed under the sink.

Thank you for your response. I am most certain they are carpet beetles, the varied and the black. I took a picture when this all began and matched it with other pictures I found online and the varied carpet beetle was the only one I found to be a match, although we do have both black and varied that I am finding. Would I need to use the permethrin as well? How often should I treat, and since eggs can hatch shortly after the first treatment should I treat again within a week or two after the first treatment? @Tech Support:

I have identified I have carpet beetles. The problem is I live in apartments. So for them its not an urgent thing. My son has gotten an allergic reaction to the larvae hairs. So now they have come and sprayed twice in one week. And still like that I see larvae moving around even in the areas I have cleaned out. What else can I do.

I’ve read your informative article and skimmed through the comments, but I still have a question. I just want to get rid of my paranoia and ask: What would you consider an “infestation”? Earlier today I found two Varied Carpet Beetles in my laundry bin and I believe I’ve found another in the past (I would say roughly a month ago). I don’t know if this qualifies me to begin treatment or not. I have read in other places as well as seen videos on the topic, but they have told me to just keep the house clean and in good order. The insects were found only in my room and I’m worrying about this because I would love to sleep comfortably without unwanted company. Please answer when you have the time.

Thank you,

We have an isolation in between the walls in my basement. The other day we found carpet beetles in there. How can we get rid of them? It’s not easy to reach the area and I know that there is are eggs and live carpet beetles in there. What do you recommend ?

At this point we are planning on taking down the walls and removing all the isolation we have on the basement.

Please help ?
