These spiders are dark brown to black, with tiny, silky hairs covering their bodies. Females can grow up to 18 mm, which is generally larger than males. Their webs, often funnel-shaped, serve as both their home and a trap for prey.

The web is constructed from a messy tangle of silk that effectively traps insects such as flies, beetles, and moths.

Black House Spiders are excellent web builders, creating intricate webs that serve as their home and a trap for unsuspecting insects. They are mostly nocturnal, hunting at night to avoid predators.
