When food is scarce, cellar spiders have also been known to eat each other too. Amazingly enough, the forelegs of an adult female cellar spider can grow as long as 50 millimeters single female cellar spider can produce up to 3 egg sacs in her lifetime. Each sac can produce up to 60 spiderlings. This particular spider feasts on small moths, flies, mosquitoes, and other insects and small pests. Cellar spiders hold their egg sacs in their mouthparts until the offspring hatches. 3 For example, if you find something that is the size of a soccer ball, then this is not likely to be a spider egg sac. Not only dwelling in these spaces, cellar spiders also nest in crawlspaces, closets, attics, rock piles and other environments that are both dark and offer plenty of humidity. Observe the size of the sac (or sacs) to determine if it might have been made by a spider. These house spiders in Ohio are also commonly mistaken for daddy-long-legs, however daddy-long-legs are not actually spiders. They live primarily in basements and cellars, which is how they earned their name.

The long-bodied cellar spider female can make three egg sacs (the sacs each have 13 to 60 eggs). Both species have medium-sized eyes, bodies up to 8 mm long, and a colour that is grey, light brown or pale yellow. Females wrap their eggs in a few strands of silk and carry them in their chelicerae (jaws) they may lay up to three egg sacs in her lifetime, each one about 30 eggs. Long-bodied cellar spiders have a 2-inch leg span while the short-bodied variant has a 1/2-inch leg span. Generally speaking, there are two cellar spider species in Canada – long-bodied and short-bodied.
