Diet & Feeding

Carnivorous predator that feeds on bed bugs, silverfish, spiders, flies, and other small arthropods.

Behavior Patterns

The nymphs secrete a sticky substance that causes dust and debris to adhere to their bodies, creating camouflage to ambush prey. They are nocturnal hunters.

Risks & Benefits

Generally beneficial as they eat household pests like bed bugs and termites. However, they can inflict a painful bite if handled or threatened, similar to a bee sting, though it is not medically dangerous.
