Broad-faced Sac Spider

Natural Habitat

Commonly found indoors in homes, especially in corners, cracks, and crevices. Outdoors, they can be found under rocks, logs, bark, or in leaf litter. They do not build typical webs for catching prey but may create silken retreats (sacs) for resting or molting.

Diet & Feeding

Primarily other small insects and arthropods, which it actively hunts and preys upon.

Behavior Patterns

This spider is nocturnal and actively hunts its prey without using a web to capture it. It is known for its speed and agility. During the day, it often hides in secluded, dark places.

Risks & Benefits

Potential Risk: These spiders are known to bite when provoked or trapped. Their bite is often described as feeling like a bee sting, and symptoms can include localized pain, redness, swelling, and sometimes a small lesion or blister, though serious reactions are rare. Potential Benefit: They help control populations of other common household pests, acting as natural predators.
