Natural Habitat

Typically found indoors in dusty corners, attics, and crawlspaces, but they originate outdoors in dry habitats.

Diet & Feeding

Carnivorous predator; feeds on bed bugs, silverfish, ants, flies, and other small arthropods.

Behavior Patterns

The nymphs actively camouflage themselves by sticking dust, lint, and sand to their bodies using sticky secretions, making them look like a walking ball of dust. They are solitary hunters.

Risks & Benefits

Generally beneficial as they eat household pests like bed bugs. However, if handled or threatened, they can inflict a painful bite, similar to a bee or wasp sting.
