Adult centipedes hide in moist, dark and secluded areas during winter. They place eggs in dampened soil during summer or spring. As centipedes become adults, they grow a complete set of legs and extra segments. Most centipedes live for more than a year and some up to six years. Centipedes may enter houses and buildings, but they do not roam during daytime. They hide in damp areas around bathrooms, closets, basements and other sites typically infested by pests.
Centipedes detect prey through the use of their antennae, which are covered with dense hairs. Their prey is immobilized by venom injected from the maxilliped fang and held in place by the maxillipeds. Prey is passed to the mouth via the first and second maxillae and is then broken down by the mandibles. Most centipedes are carnivorous and prey upon soft-bodied insects, spiders, worms and other arthropods, including other centipedes.
Centipedes are not likely to consume wood. In actuality, arthropods commonly known as wood eating centipedes are millipedes. While millipedes do closely resemble centipedes, millipedes are herbivores and detritivores, subsisting on dead and decaying plant material, including wood or cellulose material.
Signs of an Infestation
Centipedes typically leave no direct signs other than the sighting of the centipede itself.
Cultural Control & Preventative Measures
Because centipedes feed on insects and other arthropods, eliminating their food sources is a step toward controlling centipedes. For this reason, it’s ideal to identify all other pests inside houses and buildings before performing any pest control. Although centipedes may help homeowners get rid of insects like cockroaches and houseflies, large species could produce bites that are as painful as bee stings. Some centipedes can run quickly when disturbed. When they are handled, centipedes may bite, causing severe pain, numbness, discoloration and inflammation. For common house centipedes, setting sticky traps can be a way to accurately gauge centipede population levels. This activity will also help to identify potential routes of access within your home. If an infestation is confirmed, homeowners should try to reduce moisture and seal entry routes to the house or dwelling. Moisture in a building’s foundation can be a problem and lead to an infestation, as can water accumulated from the roof. Keep leaves, wood, compost and other organic material away from the sides of the home or building.
Centipedes are a diverse group of Arthropods with a range of behavioral characteristics. Therefore, when centipedes become a problem, the first thing to do is contact a Bucksworth professional and request an inspection. Once the inspection is complete, a Bucksworth professional will prepare a centipede treatment plan designed to control the centipede species causing problems. Centipede treatment usually involves both non-chemical and chemical control methods, but the treatment plan will emphasize finding where centipedes are located and how they are getting inside the home.
Some non-chemical treatments that may be included in the treatment plan include:
- Reducing moisture problems by repairing water leaks or using dehumidifiers
- Reducing clutter that provides centipedes with protection and a place to hide. Your pest management professional will likely point out these places and recommend not allowing stored items to be stacked right up against the wall or rest directly on the floor.
- Reducing the number of insects and spiders that provide a food source for centipedes
- Sealing holes, cracks and gaps that enable outdoor centipedes, insects and spiders to get inside a home
- Removing indoor centipedes with a vacuum
Generally, chemical control methods are used for temporary centipede control. If needed, your pest management professional will use insecticides in cracks, crevices and other centipede harborage areas. If the centipede population is especially heavy outdoors, the plan may include chemical applications to the cracks or gaps in the foundation, in the crawl space or the mulch around the house.
