Natural Habitat

Often found indoors in dusty corners, attics, basements, and under furniture. They seek out dry areas where other household arthropods live.

Diet & Feeding

Predatory; feeds on household pests including bed bugs, carpet beetles, silverfish, and earwigs.

Behavior Patterns

The nymphs secrete a sticky substance that causes dust, lint, and debris to adhere to their bodies, creating effective camouflage (looking like walking dust bunnies). They are active hunters that stalk their prey.

Risks & Benefits

Benefits: They are beneficial predators that reduce populations of household pests. Risks: If mishandled or threatened, they can inflict a very painful bite, though they are not aggressive toward humans and do not carry diseases.
