Natural Habitat

Wall crevices, corners, eaves, basements, and other sheltered structures. This dense, sheet-like web is attached along a brick-mortar gap.

Diet & Feeding

Carnivorous; captures flies, mosquitoes, moths, and other small arthropods that contact or become trapped in the web.

Behavior Patterns

The spider typically waits in a concealed retreat connected to the web and rushes out to seize prey. Webs are renewed or expanded as they become dusty or damaged.

Risks & Benefits

Common house-web spiders are generally harmless to people and beneficial predators of nuisance insects. Bites are uncommon and usually occur only if a spider is trapped against skin.
