Natural Habitat

Often found indoors in dry, dusty locations like attics, basements, and behind furniture; also found outdoors in hollow trees and overhangs.

Diet & Feeding

Strict predators that feed on bed bugs, earwigs, silverfish, and other small household arthropods.

Behavior Patterns

Nymphs stick dust, lint, and debris to their bodies as camouflage to ambush prey and avoid detection. This sticky coating makes them look like a walking ball of fluff or debris.

Risks & Benefits

Benefits: Useful biological control against household pests like bed bugs. Risks: Bites can be very painful if handled, though they are not aggressive toward humans and do not transmit disease.
