Attributes of Cellar Spiders

To distinguish them from other spiders, you may need to examine their palps, face structure, carapace markings, and eye groupings. 

Many common spiders in this family have 8 eyes arranged into three groups: 2 in the center of the face, and a cluster of 3 on each side of the central pair. Cellar spiders are also known for their habit of hanging upside down in their webs. If you’re having trouble identifying a spider in your home, it’s always a good idea to contact a pest control professional for assistance.

These webs can accumulate dust and debris, making them unsightly. You may also notice an increase in the number of spiders you see in your home. If you suspect an infestation, contacting a pest control professional to assess the situation and recommend the best course of action is best.

What happens if a cellar spider bites you?
