Cellar spider (daddy-longlegs spider)

Indoors, especially quiet corners, basements, garages, and ceilings where it builds loose webs.

Catches and eats flies, mosquitoes, moths, and other spiders in its web.

Makes irregular, tangled webs and vibrates rapidly when disturbed. Females carry a small egg bundle in their jaws; spiderlings disperse after hatching.

Harmless to people and pets; its bite is rare and medically insignificant. It can help reduce household insect pests.
