They also may be seen darting for cover when a light is turned on in a dark room. Occasionally, a startled centipede may run at the person entering the room, giving the incorrect impression that it is attacking. Except for the largest species, centipedes cannot bite through skin, so hazard to humans is remote. Bites are extremely rare, because centipedes are light shy and bite only when being picked up or crushed. The bite of the largest species is reported to cause a sharp, temporary pain, similar to a bee sting.
Infestations usually involve only a few individuals.
Extreme situations in homes may require insecticides as indicated for millipedes. Interior applications of insecticides are not recommended. They feed on decaying vegetable matter and occasionally small plants. They do not bite and are harmless to humans. During some times of the year, particularly after extended wet spring weather, sowbugs and pillbugs may move into homes.
