Natural Habitat

Often found indoors in homes, attics, and basements where dust accumulates; naturally found in wooded areas and hollow trees.

Diet & Feeding

Carnivorous predator; feeds on other household arthropods like bed bugs, termites, earwigs, and silverfish.

Behavior Patterns

The nymphs secrete a sticky substance that causes dust, lint, and sand to adhere to their bodies, creating effective camouflage. They are ambush predators that stalk their prey.

Risks & Benefits

Generally beneficial as they eat household pests. However, they can inflict a painful bite if handled or threatened, which feels like a bee sting, though it is not medically significant.
