Broad-faced Sac Spider (possibly)

Natural Habitat

Often found indoors, under bark, rocks, or other sheltered places outdoors throughout North America, particularly the eastern U.S. and Canada.

Diet & Feeding

Predatory, feeding on various small insects and other arthropods. They actively hunt their prey at night rather than building webs to catch them.

Behavior Patterns

Nocturnal hunters. Unlike many spiders, they do not build webs for prey capture but construct silken sacs for resting, molting, and egg-laying. They are known for being quite fast-moving. Their bite is generally not considered medically significant, though it can be painful.

Risks & Benefits

Risks: While their bite is not highly venomous, it can be painful and cause localized redness, swelling, and itching, similar to a bee sting. Benefits: They help control populations of other insects, acting as natural pest control agents.
