House spider web (likely funnel or cobweb spider)
Agelenidae or Theridiidae; species cannot be confirmed from the web alone
- Order & Family
- Araneae; likely Agelenidae (grass/funnel weavers) or Theridiidae (cobweb spiders)
- Size
- The spider is often about 4–15 mm long, depending on species; the web itself may span several centimeters.
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.
