They will do that by using their webs to capture the insects and other animals first before injecting venom to kill them off completely.įun Fact: Cellar spiders are often seen as an effective type of insect control! They even scare off other, more venemous, spiders.Ĭellar spiders, or daddy long leg spiders, tend to hide inside their webs which they’ll create in corners. Pholcidea spiders, or daddy long legs, are carnivores, which means they’ll eat insects for their survival. They like corners and darker areas of our houses where they can create, which they will hang from. ![]() These are the spiders that we commonly see in our homes because they spend the majority of their lives in houses.

Although their bites are harmless to humans, their webs are unsightly and profuse: unlike other spider species, cellar spiders prefer to live within close proximity to one another, creating troublesome communities within human dwellings. The web of the cellar spider is irregular, with no discernable pattern. Male and female cellar spiders may be found in climate-controlled structures year round. The cellar spider is often found in damp locations like basements, crawl spaces and cellars, which is how it got its common name. Because of their long legs, cellar spiders are often mistaken for daddy longlegs. The most common Phlocidae in the United States is the long-bodied cellar spider.
