Are Cellar Spiders Good?

Just as their name implies, cellar spiders are often found in damp cellars, crawl spaces, and basements. Cell spiders can be identified by their long legs and are often confused with daddy-longlegs. However, cellar spiders are pretty standard, and there are about 20 cellar spider species located in the United States and Canada.
And let’s get right to the answer to your question – are cellar spiders good? Though many people don’t like spiders and their creepy-crawly nature, the truth is that many spiders benefit our environment. It’s no different with cellar spiders as they eat insects and even other spiders that are larger than themselves. So, if you have cellar spiders in your house, there is a good chance that you won’t find any other spiders or small insects in your house.

Are cellar spiders venomous?

Cellar spiders are not venomous, nor are they poisonous. Further, cellar spiders aren’t known to cause harm to humans as they don’t bite. But for whatever reason, there seems to be an urban legend out there that the venom of the cellar spider is not only venomous but some of the most dangerous spider venom there is. There is simply no proof that confirms this belief, however. And quite frankly, the short length of the cellar spider’s fangs makes it nearly impossible for them to render a venomous bite.

How Do You Control Cellar Spiders?

Even though cellar spiders do good things for us, we don’t necessarily want them around. If you’re going to try to control cellar spiders, there are some tips- below for you to follow.

  • Use a vacuum or broom to remove evidence of spiders in your home such as webs, egg sacs, or the spiders themselves.
  • Ensure your home is properly ventilated and use a dehumidifier to remove excess moisture.
  • Seal cracks in your home, particularly around doors, windows, or other entry points.
  • Replace exterior white lights with a less attractive yellow or sodium vapor lamp. Though it might be less aesthetically pleasing, this strategy helps reduce the number of spiders as insects don’t like the yellow light.
  • Get rid of spider food sources through prevention and control measures. One of the easiest ways to do this is to hire a professional pest control service that is well-versed in dealing with pesky insects. And before using any insecticide on your own, it’s best to contact our pest control specialists. Professionals can provide guidance and insight on what to use and how much. Perhaps more importantly, they can provide insight into the potential dangers of using such products.

And the brown recluse spider is very poisonous and causes quite a bit of damage despite its small size.
