Diet & Feeding
Carnivorous predator; feeds on small arthropods like bed bugs, silverfish, carpet beetles, and earwigs.
Behavior Patterns
The nymph (juvenile stage) has a sticky body that naturally accumulates dust, lint, sawdust, and sand, acting as camouflage to ambush prey. They are nocturnal hunters.
