Lady bug control? Isn’t this sacrilegious? Every- one knows lady bugs eat many nuisance pests so why would we want to kill them? This article will explain why regions in the United States are faced with the problem of invading lady bugs. I will explain why this is happening and what you can do to stop it.
HOW DID LADYBUGS BECOME A PROBLEM?
Lady bugs do indeed eat many nuisance pests found in and around the garden. As a child, I can remember being told never to kill a lady bug as it is good to have them around the home. In the last few years, we have had increasing numbers of customers from all parts of the United States call looking for relief from lady bugs that are “invading” their homes.
At first I thought these were isolated instances that were due to certain conditions. I expected that these conditions were rare and explained to homeowners the invasion would soon subside. Too my surprise, they continued. More people began to call and it was obvious there is more than just “conditions” which were leading to these home invasions. I then conducted some research and the mystery was soon solved.
In an attempt to sell “natural pest control”, certain companies around the country have been importing lady bugs from other parts of the world and selling them. These lady bugs have been marketed as being more aggressive and hearty compared to our own indigenous species. One feature of their biology (unfortunately) is they do not die each winter. They hibernate!
So unlike our own native species, these imports like to over winter on mountainsides, rocks and caves. Such environments are readily available in certain parts of our country but not all. And since lady bugs are being released in areas where such terrain does not exist they are taking advantage of the next best thing – our homes! Watch this short video to see one of these “pests”.
LADYBUG INFESTATIONS IN UNITED STATES
I am not sure how bad of a problem this is, but we have received reports from the Northwest, the Southeast and the Southwest. What is the problem? Although ladybugs do not pose economic problems, this species seems to “flock” to homes in the fall. They seem to like a certain temperature as well as a good amount of cracks and crevices.
That means homes with cedar shakes or other wood siding are more vulnerable. And once they start to congregate in the cracks and crevices of these homes, more will come. This happens because they have a very distinct pheromone or “scent” used to alert other ladybugs that a good location has been found on which to nest. In fact there its not uncommon to see massive “balls” of them in attics where they are mating and amassing. This hibernation will last throughout the winter and then come next spring they’ll fly off to live their lives out in the open for another warm season.
LADYBUG PROBLEMS IN THE HOME
The main problem is that not all ladybugs stay hidden and out of sight. Once on the home, they’ll move under siding and into wall voids. That’s when they become a nuisance. Once in wall voids, they’ll start to appear in living areas. At that time they’ll be seen swarming around lights, TV’s, windows and ceilings. They’re usually seeking a good crack or crevice to crawl into and remain during the colder time of the year but once inside, they’re “tricked” into thinking its still warm. Consequently, they’ll remain quite active while causing a mess.
Though ladybugs don’t sting, we have had many reports from people with ladybug bites. This will no doubt happen if you handle them. So the first rule is to avoid holding them in your hand. However, large populations which are allowed to accumulate in the home will lead to more and more contact with the people. This contact will lead to bites as the ladybugs are doing what they naturally do; forage for food and use aggression as a defense when threatened.
Since food is scarce during the winter, its more likely for people to get bit during this time. In the summer they have plenty to eat and consequently don’t randomly bite in an effort to find food.
I used to advise customers to “catch and release” them back outside but not anymore. That suggestion has received many followup “mean and ornery” responses. We now recommend several treatment methods which have proven effective to control and eventually eliminate these unwanted invaders.
BEST OUTSIDE LADYBUG SPRAY
To stop them from penetrating your home, there is a product we sell which works well to both kill and repel them off your home. MAXXTHOR EC is now the best product we’ve seen come to the market which both kills them quickly AND repels them. Simply spray the sides of your home where ladybugs are invading (start up high around the gutters and be sure to get the entire side with activity) and you’ll be able to kill any present as well as keep new ones from coming around.
The following “short video” (less than 60 seconds long) shows us using our GREEN TOPPED HOSE END SPRAYER to treat the exterior of a home to both kill and repel invasive pests. The rate used in this video will work fine for Ladybugs too.
As you can see in the video, mixing up the Maxxthor in the sprayer is easy to do and using the power of your garden hose, you can reach up to the gutters effectively with our hose end sprayer.
Maxxthor will provide a fast kill along with a good residual action that can last 3-4 weeks. But if ladybugs continue to keep coming, spray again in a week. Mix 1 oz per gallon of water and expect to get 800 sq/ft of surface area coverage per gallon. That means most homes will require 2-3 gallons of mixed material to get a good protective barrier in place.
To get the most of your treatment, add SPREAD-X BOOST to your tank mix along with the Maxxthor. Boost is an adjuvant, also known as a wetter spreader or spreader sticker. It basically makes water and the mixture more “slippery” so you get better coverage. Treatments will spread 2-3 times wider and penetrate deeper. This is super important when treating for pests like ladybugs who have a protective waxy shell on their bodies. Boost will help the Maxxthor penetrate this shield leading to faster kills and more repellency on treated surfaces. Maxxthor will penetrate home siding deeper too allowing for longer residual action.
The following short video summarizes why Boost can help deliver your treatment better.
Add no more than the rate you’re applying the Maxxthor so in this case, if you’re adding 2.5 oz of Maxxthor to the hose end sprayer, add 2.5 oz of Boost too before adding water. If you’re adding Maxxthor to a pump sprayer at the rate of 1 oz per gallon, use 1 oz of Boost.
Regardless of how high your home is, you need to reach the gutters and soffits as these are key points of entry leading to your gutters. So if you only need to reach 15 feet up, our standard PUMP SPRAYER will do the job.
For homes 20-30 tall, you’ll need our 6 GALLON HOSE END or our BUGSPRAY NO PUMP SPRAYER to reach all surfaces.
Our 6 Gallon Hose End uses the power of your garden hose to spray the mixed solution up and can reach at least as high as you can spray water from the hose. To get as high as possible, remove the little black tip deflector which pulls off easily. This will let the sprayer propel the spray like a laser up to high locations.
The BUGSPRAY NO PUMP SPRAYER is for sure the “easiest” to use and the highest reaching option. It can spray up and over 30 feet and has no moving parts. Just add water, chemical and clamp on the lid. Next fill it with air using an electric tire pump. When loaded to 80 psi, she’ll spray over 30 feet high!
The following video shows the 5 GALLON NO PUMP in great detail.
What makes her extra special is that one filling of air will allow you to empty the sprayer and all the while she won’t loose much pressure. Even as she empties she’ll be spraying over 30 feet so she’s great for hard to reach locations or remote treatments where you have no way of dragging a water hose.
BEST LADYBUG SPRAY FOR INSIDE THE HOME
Once in the home, ladybugs will be on walls and ceilings. They typically enter around windows so this is one of the areas you really need to treat thoroughly using a good crack and crevice aerosol. The best option for this is our oil based FS MP AEROSOL.
FS MP will both kill on contact but also penetrate wood and “lock in” providing long lasting residual.
The following “short video” (less than 60 seconds long) summarizes why its such a great tool for pests like ladybugs.
As you can see in the video, FS MP is perfectly suited for strong pests like Ladybugs. A thorough treatment for windows will take some time but if you do it properly, you can eliminate this as an entry point.
To see how to intensively treat a window, watch this next informative video.
Treat all windows, doors and under baseboards as well.
Ladybugs may be entering at these points but once they’re inside living spaces, they often times find cracks and crevices around the flooring where they like to hide. So they may not be coming from these locations but rest assured, they could be living there during the winter if left untreated.
WHAT ABOUT WALLS AND CEILINGS?
Now often times the ladybugs will just migrate to open areas on the ceiling or wall. FS MP is NOT for these areas as its oil base will stain.
For open areas, lightly mist MULTIPURPOSE INSECT KILLER. Its low odor and water based so that when sprayed properly, will not stain.
The following “short video” (less than 60 seconds) shows how to apply Multipurpose to walls and ceilings.
As you can see in the video, Multipurpose won’t stain or make a mess. It comes out as a light aerosol, its water based and has no odor so ideally suited for sensitive areas like walls, rugs and even furniture.
Use it at the rate of 10 seconds for every 10 feet by 10 feet of wall or ceiling area.
If spraying up, be sure to wear goggles.
Multipurpose will both kill and keep them off the treated surface for 2 weeks or more but is safe enough to retreat daily if they keep coming back.
WHAT ABOUT AIR VENTS AND ELECTRIC OUTLETS
Ladybugs entering attics will like to crawl under insulation seeking warmth but in the process, they’ll find air ducts for you homes central heat and a/c system. The vent covers in the ceiling will have spaces between the air duct and the ceiling that will allow them to crawl out and into your home.
The following video shows how to treat these locations.
As you can see in the video, the air ducts have a bunch of ways for ladybugs to enter living spaces.
But so does electric outlet covers and light switch covers. These covers should be removed and treated as shown in the video.
To treat these access points, FS MP can be used but it won’t last but a month or two. The best option for these ports of entry is clearly DEMISE DUST.
This dust is highly repellent to all insects as it dehydrates them. But it will also flush them out and it will last 6-12 months.
Well suited for attics and crawl spaces, treat any void or route of entry for the longest lasting option available.
Plan on using just 2-3 squirts per electric light switch or outlet; 4-5 per air vent.
To best apply the dust, use our HAND DUSTER.
And for attics, our DUSTIN MIZER will propel it 10-20 feet.
The following video shows how the dustin mizer works.
The Dustin Mizer is handy when treating hard to access crawl spaces or attics which are wide but have no place to walk.
And since Demise Dust will last a year or longer, you won’t have to treat frequently. In general, a good dusting will last 1-2 years.
LADYBUG TRAPS
If you’ve sprayed the outside and still have ladybugs inside, FS MP and Multipurpose can be enough to knock them out if used properly.
But if you need some help OR if you have a light problem with very few ladybugs inside, consider our LIGHTED LADYBUG TRAP. This uses a pheromone lure but also has a special UV lamp ladybugs naturally seek.
The trap can hold hundreds of ladybugs and can be used inside or outside. It will catch the most ladybugs of any trap on the market as well stinkbugs.
In fact its considered one of the best STINKBUG traps on the market but from our results afield, it works equally as well for ladybugs.
Now when using traps, its important to remember that traps alone are not designed to eliminate or control ladybugs without spraying as detailed above. So please, don’ get any traps with the hope they’ll get rid of every ladybug in your home. Now will they help? Absolutely. And they can have a significant impact meaning they’ll “remove” the majority of the activity in rooms where deployed.
The following video summarizes how our trap works.
To achieve the best result using a trap, you’ll need to keep it active all night long in a dark room with no other lights on. Set out one trap per 600 sq/ft.
ORGANIC LADYBUG REPELLENT
If you only want to repel ladybugs and not kill them, PEST AWAY might be the way to go. It can be sprayed at the rate of 2 oz per gallon of water and sprayed on both your home and plants.
Pest Away is made with all natural organic essential oils and gets mixed with water. It won’t harm any wildlife, insects, birds, pets, etc. but due to it being so concentrated, it makes insects “wary” of the treated area. They will avoid where its been applied and so spraying the homes siding , especially around windows and doors, can be a great way to deter them and keep them away.
The following “short video” (less than 60 seconds long) gives the quick summary of how Pest Away works.
Use one gallon of mixture for every 800 sq/ft.

Thank you for the info on the lady bugs. Where do I purchase the Maxxthor and what is the price of this and also the FS MP aerosol? I have found the lady bugs on my deck and by the bottom of the brick on the outside of house and they also crawl on the window above deck.

Glenn says
My home is over 100 yrs. old and I’ve had to seal against bats and other insects who beleive this is their home. My pest control tells me not to worry about certain insects because the house was treated with lindane powder back prior to me purchasing it. Now I have ladybugs invading and they die as soon as they come into the house, so I will try the maxthor and spray in the attic and around windows upstairs, hope it will work. I will remember to treat this fall. The ladybugs really make a mess, I just hope this spray will deter them from coming here as their home.
Tech Support says
Spraying the outside of the home will no doubt deter and repel this invasive species. And in the attic, spraying around routes of entry will help too. But as explained above in our article, the Demise Dust is the best long term control for the attic space with treatments lasting a year or more.
As for the living spaces, the FS MP is best suited at keeping them out and the Multipurpose for open areas where they like to roost.
Ladybugs will use whatever unprotected structure they find on which on which to hide and hibernate. I treated two years ago and that did them in but this past fall, they must have come back. I just never saw them. Now we’re seeing a few inside, around the windows trying to keep warm by the sun, and these two products took care of this problem easily.

Please help me eradicate these creepy biting ladybugs that invade my home every winter and stain their feces everywhere.
Tech Support says
I’m sure we can help. For starters, I suggest you read the article above to learn about the various methods of control you can do. There are also some video’s worth viewing that cover a lot about the treatment methods you’ll need to do for this pest.
As you’ll learn, you may have to spray just the outside of the home if that’s the only place you see them now. This should be done every fall, before they come, to keep them off and away from your home. And the material you’ll need to spray with is Maxxthor. It’s quick acting and long lasting on ladybugs.
.
Maxxthor EC: https://bugspray.com/catalog/insecticide/liquid/maxxthor-ec
.
Now once they’re inside the home, you’ll still need to spray the outside with Maxxthor but you’ll also have to start using one of the aerosols we have listed like the FS MP at least and maybe the Multi Purpose for inside treatments.

FS MP: https://bugspray.com/catalog/insecticide/aerosol/fs-mp-insecticide-15-oz-aerosol
Multi Purpose Insect Killer: https://bugspray.com/catalog/insecticide/aerosol/multi-purpose-insect-killer-10-oz
.
There are other control methods listed in the article you may need to deploy but in general, these are the three main treatments needed to get ladybug infestations under control. Give us a call if you have further questions or need help. Our toll free is 1-800-877-7290.

All the information above, products and uses including customer comments are very informative. However, I have one important question: infant safety inside home; 4 and a 1 yr. old and using either the FS or multi. Please don’t say self explanatory, I’m 73 yrs old. Thanks. Please reply soon.
Tech Support says
Your concerns are warranted but for the products we have listed above, not an issue when used properly. Basically you only have to have the kids and pets out of the area when treating and once the treatment is able to settle and dry, the residual will not pose a hazard to anyone.
In fact, most every product listed above will have a “safety video” toward the bottom of their respective product pages in our cart. These video’s go over how to safely use the material, how to store it, mix it, etc. Definitely review these video’s as they are very informative.
Additionally, we have more information on this topic posted online which should answer most any other concern. Check it out by following this link:

How do you dust an attic when the house is 50 years old and we do not feel the attic is safe enough to crawl around in – let along be able to get up in it. Thanks!
Tech Support says
Use the Dustin Mizer listed in our article. So all you’ll need is an entry point, like an attic door, and at that entry point, the Dustin Mizer should be able to blow the dust a good 25-30 feet in all directions.

What is your definition of “fall” as far as San Antonio, TX is concerned?
Tech Support says
@Karen Haman: Karen,
Funny you should ask. I was visiting San Antonio back in 2015 at the end of September in 2015 and it was HOT! I remember thinking when, if ever, did fall arrive to this part of TX? Well after talking to some friends, I would say that you would not want to wait for your first fall treatment past the end of October. And based on our customer base in your region, it would appear that most begin to have issues late October and certainly by November.
Cheers,
Jonathan

Live in South Western Part of NC on a mountain top. I have purchased and used Maxthor to control the Asian Lady Bugs. I am not exaggerating one bit here, when I say, for periods, usually early November, our home annually gets hit by thousands of these Lady Bug Pests. The Maxthor, plus all the cucking I have done around our doors and windows, has definitely stopped them from entering our home. But, during that period of time each year, I am left with the chore of cleaning up dead carcasses each and every day. As mentioned our home is on the top of a mountain, and main exposure facing South. Our neighbors DO NOT have the issue of being invaded every year by these pests. Again, the product I have purchased from you folks is working, BUT, any ideas WHY these pests choose our home over others? I would love to hear your comments, and or suggestions. PLEASE and thank you.
Tech Support says
Doug,
Great feedback! And though its not possible for us to answer your question with one specific reason, its most likely a combination of factors. And here are three we know can be important.
So first, homes that are “atop” a ridge facing south or southwest tend to get targeted. This means “position” does matter.
I happen to have the “tallest” home in my subdivision and it sets atop a bluff which overlooks the Chattahoochee river. The back of my home faces southwest and I too find that at some point in November, we’ll have hundreds if not thousands appear requiring a treatment with Maxxthor.
Second, the color of the home can be important. In most cases, white seems to be a color they’ll target but this is not written in stone. My home has some white siding in a few areas and these are the only areas they target.
Lastly, it does appear that once a home has any active for 1-2 years, the structure gets “marked” and in turn, has ongoing issues. As our article above explains, its very clear that homes which get a problem for 1-2 seasons tend have it only get worse if left untreated. This tends to happen because first, pheromones left by the beetles in the past are detected by currently active beetles when they start looking for a home to over winter on. But also the offspring of the ladybugs that have used the home before are no doubt “wired” to find the places their DNA “knows” about.
In summary, its no doubt a combination of things involved and any one of them could be more significant than the others. But trying to identify which is most important for any one home is a mystery we may never solve.

Good morning Jonathan. Quick update on our ladybug issue, which we addressed with you close to a year ago now.
The great news is….being the middle of November now, we can report that other than a couple of days with what I would consider a moderate invasion, they have not been an issue this year.
The moderate invasion consisted of a few days when we would find about 15 or so dead ladybugs lying on our deck. NOTHING compared to the hundreds and hundreds we had every year for the past 10 years plus.
As per your instructions, I sprayed the exterior of our home with the NNz in the spring and again the fall, and followed up by spraying the home with MAXTHOR.
