How To Identify Cellar Spiders

Cellar spiders can be pale yellow, light brown or grayish color. They have a distinct small body (1/4”-3/8”) with 8 long and skinny legs. Cellar spiders are often referred to as ‘daddy longlegs’, though this is not accurate because they are not true daddy longlegs. In fact, true ‘daddy longlegs’ are not actual spiders.

Why Do I Have A Cellar spider Problem?

Cellar spiders thrive in areas with high humidity. Cellars, under sinks, and bath traps are all common places to find these arachnids.  You might also encounter them in sheds, garages and barns.  They not only live in dark damp places, they also hunt there.  

Are Cellar Spiders Dangerous?

Cellar spiders are not dangerous. They are not aggressive and their mouthparts are too weak to actually bite a human. They most certainly, however are a nuisance within a home. They create irregular webs that they continually add onto. These social spiders live close together and can create large communities within homes.

  • Seal all potential entry points around windows, doors, and the foundation.

  • Reduce humidity levels by making sure that basements, attics, and crawl spaces are well ventilated and use de-humidifiers where appropriate.

  • Fix any leaky pipes or fixtures in your home that would create the damp conditions they prefer.
