Under bark and stones, in leaf litter, caves, and homes
Importance
Importance: They are not pests and are considered harmless. Even though most individuals have poison glands, the animals are not large enough to bite people. Can run backwards with ease. Often hitchhike on beetles to disperse. None are known to be parasitic but they feed on arthropods in bird and rodent nests. They are sometimes found on beetles or other large insects where they apparently feed on mites.
Range
Worldwide

Under bark and stones, in leaf litter, caves, and homes
