Cellar Spider

Cellar spiders have long bodies and legs and are one of the most common house spiders. They build wide erratic webs for entangling prey, primarily in cellars, garages, basements and sheds. In homes with heavy problems, they can be found nesting by windows and corners throughout the home. To get rid of cellar spiders, please see our discussion on getting rid of spiders.

Cellar Spider Identification

Cellar spiders have a brownish transparent tone, with a relatively small body. The abdomen and carapace are the same color, and the face of the spider is equipped with two rows of three eyes. Due to their long legs, they are sometimes confused with the grand daddy long legs. Some people refer to the cellar spider as the true daddy long legs because the latter isn’t actually even a spider. Because the webbing lacks adhesive properties, females are forced to carry eggs with their chelicerae (spider jaws).

Behavior & Facts

Cellar spiders do not have sticky webs. They rely solely on the chaotic shape of their web to entangle prey. The lack of adhesive webbing makes it easier for the cellar spider to negotiate its steps and quickly attack any insects that get caught. A strong indicator of cellar spiders is the presence of cobwebs, which they are notorious for constructing around the home. Outdoors, they will construct webs in shrubbery and around the eaves of the property.

Cellar Spider Bite

There is no evidence to indicate a cellar spider has ever bitten anyone. A common urban myth is that the daddy long legs (which many consider to be the cellar spider) is the most toxic spider on the planet but its fangs are too tiny to bite. This myth is very widespread and completely false. Unless you are bitten by a black widow or brown recluse, you don’t have very much to worry about.
