Jumping spiders (family Salticidae) are generally considered harmless to humans. While they possess venom glands and fangs like the vast majority of spiders, their venom is primarily used to immobilize and subdue their prey, which consists mainly of insects. Jumping spiders are not known to pose a significant threat to humans, and their bites are usually harmless and rarely cause any significant reaction. In the rare event of a bite, any discomfort or symptoms are typically mild and resolve on their own without medical intervention. However, individual reactions can vary, so if you experience an unusual or severe reaction to a spider bite, it’s advisable to seek medical attention.
