These spiders create disorderly threads of webs to create their shelter. They create their homes in woodpiles, sheds, loose bark, under rocks, tires and inner tubes, and in dry places.

When they do go out from their webs, they will do this at night. Males usually leave their webs during the night so that they can hunt their prey. Females on the other hand, prefer to stay near their web or just remain there waiting for a prey to come by.
