- SAWTOOTH BEETLE CONTROL FOR THE PANTRY AND HOME
SAWTOOTH BEETLE CONTROL FOR THE PANTRY AND HOME ^
Sawtooth Grain Beetles are a small brown to black beetle measuring 1/4 to 3/8th inches long when fully grown. They are among the most common of pantry and cabinet infesting beetles and will readily enter homes from outside areas where they commonly feed on bird seed, flower pollen and more.
SAWTOOTH BEETLE BIOLOGY ^
Sawtooth beetles have been around as long as other flour beetles. Their history dates back several thousand years. This is due to the fact most ancient civilizations used flour as a primary food ingredient.
Sawtooth beetles thrive on flour dust though they will readily feed on just about anything found in the home intended for people or pets. Sawtooth beetles are cosmopolitan and can thrive in any part of the United States.
SAWTOOTH GRAIN BEETLES IN THE HOME ^
Once in the home, sawtooth beetles will readily feed on pet food, cereal, pasta, spices, rodenticide, dried fruit and vegetables, eggs of other insects, nuts, grass seed and just about anything which can provide nutrition.
Unlike other pantry pests, sawtooth beetles can find food which is well hidden and protected. Their strong chewing mouth parts will allow them access to food which is stored inside boxes and plastic bags. All they need is the scent of something worthwhile and they’ll make every attempt to find their way inside.
LIFE CYCLE OF SAWTOOTH BEETLES ^
Sawtooth Grain Beetles live a long time. They have an average life span over 3 years which is quite long for an insect so small. Adult females will lay a few eggs daily which will amount to over 300 during her life. Eggs will hatch in a couple of weeks and start to feed immediately.
The feeding larva will go through 2-4 molts which will occur over a 3-5 week period. After they get their fill, the larvae will spin cocoon’s where they’ll disappear for awhile. During the pupa stage, they’ll morph and eventually emerge as adults when the cycle is complete.
All this will occur in less than 2 months which makes this species of Grain Beetle one of the fastest developing species we have as a nuisance pest in the home. And since they will readily eat anything, they will always find something good to eat.
HOW TO TREAT SAWTOOTH GRAIN BEETLES ^
Whether they’re brought home in cereal, pet food or pasta, Sawtooth Beetles are a nuisance once in the home. Like most pantry pests, there are a few things which must be done to break their cycle once established. Here is an outline of what to do.
First, empty all your kitchen cabinets, shelves and closets where they’ve been seen or thought to exist. Food stuff which has them active must be discarded in sealed plastic bags. This will help contain them until the garbage is picked up.
If you are not sure if something is infested, store it in a plastic bag and check the bags every few days. If you find Sawtooth Beetles active, it will mean the item is infested and should be thrown away immediately.
Since this pest is temperature tolerant, don’t waste your time trying to “freeze” kill adults, eggs or larva. No doubt you’ll get the active stages. But many will survive fine and these will be able to continue the cycle.
Once food stuff which is thought to have activity is discarded or stored in a clear liner for observation, you’ll be ready to prepare for a treatment. But before you treat, vacuum all closets, shelves and baseboards. This will help remove eggs which are usually too small to see. Sawtooth Beetles lay eggs with a glue like excretion which helps to attach them to surfaces where food is typically available.
VIDEO TRAINING OF HOW TO TREAT A PANTRY ^
The following video gives you an in depth look at how to treat any pantry using either FS MP Aerosol, Bithor or both. The products in the video are listed below and for most all homes, using both is the best way to procee because once in the home, the active adults can migrate to many areas.
For this reason the FS MP Aerosol should be used in specific locations where you know they’ve been active and then the Bithor distributed on baseboards throughout the rest of the home or even on carpeting or furniture if the target pest has been seen in any of these locations.
The following video presents the “long” version of how to thoroughly treat for this pest to eliminate them all.
TREAT CABINETS FOR SAWTOOTH BEETLES ^
Once everything has been removed from your cabinets and they’ve been vacuumed, proceed with a treatment. There is only one good options for pantries and kitchen cabinets that can kill all stages. FS MP AEROSOL is literally all you’ll need. Its penetrating invasive solvents will kill eggs, larvae, pupae and adults on contact.
The following “short video” summarizes why its so good for treating cracks and crevices in the home.
If you thoroughly treat any room, cabinet, wall void or other space where they might be living or nesting, you can kill them all off with one good application.
FS MP is fast acting so if you still see activity 3 days after you treat? Spray again.
Realize that any you are seeing must be coming from some nearby location so focus your application on where you’re seeing them. Be prepared to spot spray every 2-4 days and if you follow this routine, you can knock out all nests within a couple of weeks.
Be sure to let the treatment dry 1 hour before returning dishes and food stuff back into the cabinets and really, letting cabinets remain empty for a few days until you know the problem is gone is the better approach.
BEST SAWTOOTH GRAIN BEETLE SPRAY ^
For extensive problems that stretch into all areas of the home, you’ll be better served using a liquid. Laundry rooms, garages, basements and other areas where pet food and grain products like grass seed are stored. These areas will be prime locations for Sawtooth Beetles to hide and nest so if you have a lot of home to cover or a warehouse or food processing plant, go with a liquid spray. It will be easier to use, more cost effective and longer lasting.
The best concentrate for protecting the entire home is BITHOR SC. This concentrate is odorless, easily mixed with water and 1 gallon will cover up to 1,000 sq/ft.
The following “short video” (less than 60 seconds long) summarizes why Bithor is a great option for use in the home.
Bithor will kill them on contact but then that ingredient wears off and the long lasting residual won’t “spook” target insects or chase them around. Treatments will last a good 2-4 weeks and during this time, the active will be spread to others in their colony.
And for surface spraying, the MINI MISTER is the best way to apply it. The following “short video” shows how it works and why using it in the home is the best way to spray.
Add 1 oz per gallon of water and distribute this over 1,000 sq/ft of area (baseboards, carpeting, etc.). Bithor compliments the other products, FS MP and Phantom so you can use the Bithor “low”, where you can spray heavy have a lot of area to cover. Using the aerosol up “high” like in cabinets is generally the preferred way to proceed since this will give you protection both low and high and allow you to be thorough but not messy.
Since sawtooth beetles will hide in tough to reach areas, add GENTROL IGR to your tank mix for added protection.
Gentrol is a juvenile growth hormone regulator and will effectively stop developing larvae from reaching adulthood. This will be a big help because Gentrol will naturally “translocate”. This means it will effectively “move” to areas well beyond where you spray. It can be mixed with the Bithor and sprayed at the same time so it takes no more time to include it with your regular spraying.
For sawtooth beetles, add 1 oz of Gentrol to the same gallon of water with the 1 oz of Bithor and use the same exact way for up to 1,000 sq/ft of area.
You can make the treatments using a good PUMP SPRAYER.
If you want to avoid over spray, get the MINI MISTER. As shown in the video above, its ideal for making “clean” applications in the home.
SAWTOOTH BEETLE TRAPS ^
Once everything is treated and allowed to dry, install SAWTOOTH BEETLE CABINET TRAPS. These traps use strong food based attractants to lure foraging adults looking for a quick snack. They’re easy to set out and one trap per cabinet will suffice. The light brown liquid seen in the picture will be squeezed out into the triangular tray and placed discreetly in the corner. The oil smells like food but also serves as the medium that keeps them stuck in the trap. Traps will last 60-90 days but should be replaced if they fill up sooner.
Sawtooth beetles will fly or crawl into the holding tray and get caught on the thick oil.
Now for open areas, the XLURE BEETLE TRAP is better suited. This trap is quite durable. Its made with a hard plastic body and the inside chamber houses the special catching gel, food bait and some mild sexual pheromones. Set one trap every 15-20 feet; placements can be made under furniture and in other hidden areas as well as out in the open. Don’t let the dog eat it; the components won’t hurt any pet but the plastic isn’t good for them to eat. Change the trap every 90 days if the activity is still active this long.
Sawtooth Grain Beetles can be a persistent pest once n the home. To break their life cycle, you’ll need to remove contaminated food and treat with the products listed above.
Lastly, set out traps in any cabinet, pantry or where activity has been noted. Keep the traps fresh so they will monitor the areas to insure the problem has been resolved.
