Cellar spiders, often called daddy longlegs, have small bodies and long, delicate legs that can look wobbly as they move. They prefer dark, low-traffic areas like basements, cold storage rooms, garages, crawl spaces, and under decks. Their webs are thin and wispy, but they can build up quickly in corners, ceiling lines, and around stored items.

Cellar spiders are more of a nuisance than a threat, but heavy webbing and clusters of spiders can make a space feel unkempt fast. If they’re left alone, they keep producing webs and egg sacs, and the consistent insect activity in these areas can pull in other pests too.

BRD Pest Solutions targets cellar spider problems at the source. We remove existing webs, treat the areas where spiders hide and rebuild, and focus on reducing the insect activity that keeps them around. The goal is simple: cleaner storage spaces, fewer spiders, and less webbing coming back.

Cellar Spider FAQ

Are cellar spiders (daddy longlegs) dangerous?

Cellar spiders are generally harmless to people and pets. They’re not aggressive, and most issues are about the webs and the “spider clutter” they create in storage areas.

Why do cellar spiders keep showing up in my basement or garage?

They like dark, quiet spaces with little disturbance and a steady supply of small insects. Basements, garages, crawl spaces, and cold storage rooms often check all those boxes, so spiders settle in and keep rebuilding.

How do you get rid of cellar spiders and keep them from coming back?

Effective cellar spider control includes web removal, treating the corners and hiding spots where they rest and rebuild, and reducing the insect activity that attracts them. Sealing gaps and keeping clutter down also helps prevent repeat infestations.
