Masked Hunter (Nymph stages)

Natural Habitat

Found indoors in neglected corners, attics, and basements where dust and other small insects accumulate; also found in gardens and barns.

Diet & Feeding

Strictly carnivorous; preys on small arthropods including bed bugs, booklice, flies, and carpet beetles.

Behavior Patterns

Nymphs practice active camouflage by secreting a sticky substance and covering themselves with dust, sand, or lint (forming a 'mask'). They are nocturnal hunters that move slowly unless attacking prey.

Risks & Benefits

Benefits humans by preying on household pests like bed bugs. They are not disease carriers, but if handled or threatened, they can deliver a very painful bite that may cause localized swelling.
