Toxic to Animals

Wall spider possesses a toxic defense mechanism that primarily acts through biting with its fangs. The venom is of mild intensity and serves as a means to subdue prey. Adults are typically the toxic stage of wall spider. Exposure to this toxin can cause discomfort among various animals, including humans, dogs, cats, and birds. As a defense strategy or a method to immobilize prey, the effect on these animals can range from mild irritation to allergic reactions, although it is not generally considered life-threatening.

Bite Humans

Wall spider rarely bites humans. Bites occur typically in defense when the spider feels threatened. Despite their ability to bite, wall spider mostly avoids humans and consequences of bites are generally mild, without significant long-term health issues.
