The black house spider is also related to the gray house spider (Badumna longinqua). This species is slightly smaller and has a pale gray body and legs. However, the furry house spiders are relatively timid and tend to avoid contact with humans. Kukulcania hibernalis is a species that exhibits a great degree of sexual dimorphism. The abdomen is elongate-ovoid, and at times can be considerably distended, e.g., after feeding or if the female is gravid.

The southern house spider is partial to spaces within the masonry of buildings, especially dark recesses of windowsills, shutters and overhangs. Here a spider seeks out a sheltered crevice for a nest, around which a distinctive web is made on the adjoining substrate. Under microscopic inspection, the silk of this web appears to be "woolly," an appearance created by the action of the calamistrum pulling silk from the cribellum.
