House centipedes feed on spiders, bedbugs, termites, cockroaches, silverfish, ants, and other household arthropods. They administer venom through modified legs. These are not part of their mandibles, so strictly speaking they sting rat controlher than bite. They are mostly nocturnal hunters. Despite their developed eyes they seem to rely mostly on their antennae when hunting. Their antennae are sensitive to both smells and tactile information. They use both their mandibles and their legs for holding prey. This way they can deal with several small insect controls at the same time. To capture prey they either jump onto it or use their legs in a technique described as “lassoing”

If you want to poison the centipedes, but you don?t want to poison the earth, yourself, or your pets, you can use natural pesticides like boric acid or food grade diatomaceous earth for continual centipede control. Products containing plant-derived pyrethrin will exterminate centipedes on contact, and can be used as a fog or spray.
