Centipedes primarily enter the home unaware of the environment and are considered occasional invaders. Typically, centipedes will be found in areas of high moisture. These areas are places like loose bark in trees, rotting wooded (logs, fallen trees), under rocks, stones, or boulders, in piles leaves. Also, because they are predators and carnivorous, they will follow their prey and will reside in areas that their prey is located (which will also cause them to enter the home). When they enter the home, they will survive off of flies, spiders, etc. Even though they can be found almost anywhere in the house, because they are nocturnal or active during the night and attracted to dark, moist areas, you will typically see centipedes in damp basements, bathrooms, or even in your potted plants with high moisture.
The key to centipede control is to eliminate areas that they will most likely reside in. It is important to remove accumulations of leaves in the yard, remove rocks or stones that are near the home, safely store firewood away from the home, get rid of rotting logs and fallen trees, etc. It’s also very important to provide good ventilation in the crawl space area where moisture build up is common. Temp vents for crawl spaces will create a ventilation system for crawlspaces (CRAWL SPACE TEMP VENT)
Also, because centipedes are carnivorous, they will find prey to feed on. Eliminating the food source and doing pest control on their food source will make areas unattractive for nesting primarily because their sole purpose of nesting in a certain area is to catch prey. Although total wipeout of all pests is difficult, controlling pests that are indoors make keep centipedes away from the insides of homes.
Crack and Crevice Treatments
Crack and crevice treatment is to be used where centipedes may crawl through into the home. You will target areas of entry and cracks in the walls where centipedes can crawl through. These areas will be any areas like cracks and crevices in the bathroom, attics, windows, closets, basements, etc. You can use this treatment using liquid insecticide sprays (LambdaStar 9.7% CS, FenvaStar EcoCap ) using a hand held sprayer (CHAPIN 1 GALLON SPRAYER), dust products (DELTA DUST) using a duster (BELLOW BULB DUSTER), or aerosol spray cans (CY-KICK AEROSOL).
Liquid insecticides can be used as surface treatment as well but will be sprayed along windowsills and door frames, along the baseboard areas and with the stream nozzle applicator on the sprayer, it can be used in cracks and crevices. Liquids have about a 3-4 month residual time and should be applied thoroughly. Aerosol sprays are used in areas that the sprayer cannot reach or can be used for contact kill. Aerosol sprays do not have a long residual time and is primarily used for as an instant knock-down killer. Dust products are used as spot treatment in crack and crevice areas. Typically, dust products are not recommended for people will asthma or curious pets and children. Breathing in dust products can potentially be dangerous and so it is recommended as a spot treatment in areas that have little or no traffic (behind shelves, under furniture, behind picture frames, etc). For any liquid type insecticides (liquid concentrate or aerosol sprays), it is important to let the insecticide dry before coming in contact with the treated areas. For all products, it’s extremely important to read the product label thoroughly or to use the product after careful advisory from a professional.
Broadcasting treatments are used for large turfs, other landscape areas, and entire lawn areas. Both liquid insecticides, using a hand held gallon sprayer as well as granule products (BIFEN GRANULES), applied by using a hand spreader ( HANDLE SPREADER), is effective for broadcast treatment. Using the mist nozzle setting on the sprayer, liquid insecticide can be applied over the entire lawn area. After granules are spread, it is important to irrigate the area to activate the granules. Although grass, plants, flowers, and vegetation will not die from the liquid insecticides, DO NOT use liquid insecticides on or around fruit and vegetable gardens. The liquid insecticides have a residual time and can potentially be consumed through the plants.
A barrier treatment is a preventative method of treatment when you use insecticides to create a barrier around the home. This method of treatment is sometimes called perimeter treatment, where soil areas that are adjacent to a structure as well as a portion of the lower foundation wall next to the soil is treated. There are areas such as porches, patios, crawl spaces, garages, along the exterior walls, cellars, and etc. Spraying the liquid insecticide thoroughly will require spraying at least two feet up the wall and two feet out from the wall with a liquid sprayer. Also, granules will work the same way by setting up barriers around the home and being activated after irrigation.
