Natural Habitat

Typically found indoors in dusty corners, attics, and basements. Outdoors, they live in dry, sheltered areas like woodpiles or barns.

Diet & Feeding

Strictly confusion predators; they feed on other household arthropods including bed bugs, silverfish, woodlice, spider beetles, and earwigs.

Behavior Patterns

Nymphs secrete a sticky substance that covers their body, allowing dust, sand, and lint to adhere to them as a form of camouflage (hence the 'masked' name). They are nocturnal ambush predators.

Risks & Benefits

Generally beneficial as they eat household pests. However, if handled or threatened, they can inflict a very painful bite, similar to a bee sting. They do not feed on human blood or transmit diseases.
