Natural Habitat

Damp, dark places like under logs, rocks, leaf litter, and occasionally inside homes in basements or bathrooms.

Diet & Feeding

Strictly carnivorous; specialized to hunt and eat woodlice (pill bugs) using their large chelicerae to pierce hard exoskeletons.

Behavior Patterns

Nocturnal ground hunters that do not build webs to catch prey. They utilize silk to create retreat sacs for resting and molting.

Risks & Benefits

Generally beneficial as they control pest populations. While they can bite humans if handled, their venom is not medically significant, though the bite may cause localized itchiness or pain due to the size of the fangs.
