Masked Hunter Nymph (Dust Bug)

Natural Habitat

Often found indoors in dusty corners, attics, and basements; outdoors in woodpiles and crevices.

Diet & Feeding

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

Behavior Patterns

Nymphs intentionally cover their sticky bodies with dust, lint, sand, and debris as camouflage (the 'mask') to ambush prey and avoid detection. This behavior ceases once they molt into winged adults.

Risks & Benefits

Generally beneficial as they eat household pests like bed bugs (hence the name 'masked bed bug hunter'). However, they can inflict pain similar to a bee sting if handled or threatened.
