To understand how to deal with spider infestation in your home, let’s take a look at how the infestation occurs in the first place especially in the case of cellar spiders.

What is a Cellar Spider?

Cellar spiders (Pholcidae) are nicknamed Daddy Long Legs because of their distinctive skinny, long legs and a very small body. These types of spiders prefer to lurk in a damp environment such as crawlspaces, basements, attics, closets, warehouses and even pantries. In certain cases, you can found cellar spiders living outside in areas such as rock piles or caves.

Cellar spiders vary in sizes, their sizes range from 1/4 to 3/8 inch. Another noticeable feature of this type of spider is that they come in different colors that include tan, pale yellow, gray, and light brown.

Over 20 species of cellar spiders live in the United States. They can be categorized as short-bodied or long-bodied spider depending on their size.

One spectacular thing with their appearance is their legs; the short-bodied cellar spiders have legs that are approximately 5/6 inches long. On the other hands, the long-bodied cellar spiders have considerable small legs, their legs are approximately 2 inches long. They often build their webs in corners and hang upside down waiting for an unlucky insect to wander into the webs.

How long do Cellar Spiders live?

Cellar spiders will live for about 2-3 years. They need about 1 year to grow and reach maturity.

Do Cellar Spiders bite?

Cellar spiders have a scary look, but no need to get scared because unlike the black widow, a cellar spider is not poisonous. They lack the strength to actually bite humans. However, there is some urban myth that says the cellar spider is among the most deadly in the world but a scientific investigation of these spiders shows that their fangs are not long enough to deliver the venom during a bite. In fact, there is no scientific evidence to support that cellar spiders deliver deadly venoms.

Just because they don’t inject venom doesn’t mean they cannot harm you in other ways. A cellar spider infestation can make your home look like a haunted house; they love making a mess with their large webs which can be really annoying and unsightly. Cellar spider infestations mostly occur when your home has a good number of other types of insects. They are seen as nuisance pests. Once these spiders trap an insect in their web, they will abandon that web and create another one thereby making the mess of your space.

This type of spiders like to live in a community; what we mean is that unlike other spiders, these ones prefer to live in close proximity of one another creating what looks like an ugly spider communities within your home.

It is proper to point out that cellar spiders are very adaptive and successful predators. They come easily adapt anywhere in your home that is damp and feeds on insects by luring and trapping them within their webs and then later encase them in cocoons.

Cellar Spiders are very tricky, some see them as smart, what these spiders do when they found themselves in an environment where there is insufficient food is that they go to other webs and pretend to be trapped insects. When other spiders try to catch and eat them, they will attack the unsuspecting arachnid and eat them instead. They fend off their attackers by using wobbly, vibrating movements to confuse them.
