Natural Habitat

Often found indoors in dusty corners, attics, and basements where they hunt other household pests. Outdoors, they live in wooded areas, under bark, or in leaf litter.

Diet & Feeding

Strictly carnivorous predators. They feed on bed bugs, earwigs, silverfish, woodlice, and other small arthropods found in homes.

Behavior Patterns

Nymphs have a unique camouflage behavior where they secrete a sticky substance that covers their body, allowing dust, lint, and sand to adhere to them. This 'dust bunny' disguise hides them from both prey and predators.

Risks & Benefits

Benefits: Generally beneficial as they act as natural pest control against bed bugs and other nuisance insects. Risks: While not aggressive toward humans, they can inflict a very painful bite if handled or threatened, comparable to a bee sting.
