Size: Nymphs vary based on instar stage but are typically 1/4 to 1/2 inch (6-12 mm) long.
Natural Habitat
Often found indoors in dusty corners, attics, basements, and behind furniture; originally found in dry, natural habitats like hollow trees or bird nests.
Diet & Feeding
Predatory; feeds on other household arthropods such as bed bugs, silverfish, carpet beetles, and earwigs.
Behavior Patterns
The nymph exhibits a specific camouflaging behavior where it covers its body with dust, lint, and debris to blend into its surroundings—hence the name 'Masked Hunter.' They are nocturnal and ambush predators.
Risks & Benefits
Benefits: They act as natural pest control by eating other unwanted insects. Risks: While generally not aggressive toward humans, they can inflict a very painful bite if handled or crushed, similar to a bee sting.
