Life Cycle & ReproductionĬellar spiders hatch from eggs, and when hatched, look like small adults who shed their skin as they grow. But, so do brown recluse spiders that undeniably bite humans. But, are the fangs too short to penetrate human skin? Cellar spiders do have short fangs, termed uncate by spider experts. There is no scientific based information to support the deadliness of their venom, so there is no reason to assume this is true. However, this has not detoured the existence of an urban myth indicating that cellar spider venom is among the most deadly in the world, but the length of the spider’s fangs are too short to deliver the venom during a bite. Not a medically important spider, cellar spiders aren’t known to bite people. As the other spider attempts to catch and consume it, the cellar spider attacks the unsuspecting arachnid.Īlso known as vibrating spiders, cellar spiders utilize wobbly, vibrating movements to confuse predators and attackers. When food supplies in their environment are insufficient, these spiders travel to other webs and pretend to be trapped insects. Their diet consists primarily of insects, which they lure and trap within their webs before encasing them in cocoons. Like most other spiders, cellar spiders are highly adaptive and successful predators. They prefer to eat small moths, flies, mosquitoes and other insects or spiders that are found near their webs. 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. Though they are venomous (like 99 of all North American spiders), they are not poisonous. The cellar spider is often found in damp locations like basements, crawl spaces and cellars, which is how it got its common name. The Long-bodied Cellar Spider has very small chelicera (mouth parts) and is not known to bite people. Because of their long legs, cellar spiders are often mistaken for daddy longlegs. Common throughout the United States, these narrow-bodied spiders are about a third of an inch long, but their legs can be up to 2 1/2 inches in length. The most common Phlocidae in the United States is the long-bodied cellar spider. Cellar Spiders, commonly referred to as Daddy Long Leg spiders, are long-bodied brown spiders that have super-thin legs. There are two groups of cellar spiders, the long-bodied cellar spiders that have legs up to two inches long and the short-bodied cellar spiders whose legs are about ½ inch long. Legs: Like all spiders, they have eight legs.

If you are noticing multiple kinds of insects and arachnids in your home, you may want to measure the humidity levels and pick up a dehumidifier. If you have firewood, stack it at least 20 feet from the side of your home and inspect firewood pieces before bringing them inside. Inspect the exterior and interior of your home for cracks in the foundation. There are several ways to prevent a cellar spider infestation. In other cases, cellar spiders will move into another spider's web, pretend to be trapped, and then attack the other spider when it gets close enough. When cellar spiders see an insect approaching their web, they will pulse their bodies to make the web shake and cling to their prey. These kinds of spiders do not present a threat to humans, although they are very effective against other spiders and insects. Unlike other species of spiders that take down their webs before making new ones, the cellar spider will continue layering webs on top of each other, which leads to much more noticeable cobwebs. The long-bodied cellar spiders have legs that can be up to two inches long, while those of the short-bodied spiders can be about ½ inch.Īs the name would suggest, cellar spiders often make their homes in the damp and dark corners of basements, crawl spaces, sheds, and warehouses. Both types range in color from light tan to brown or gray, have small oval bodies, and have slender legs. There are two types of cellar spiders: long- and short-bodied.
