Are Jumping Spiders Friendly?
Jumping spiders are commonly regarded as sociable. Their huge eyes, leg and pedipalp movements, and propensity to “dance” make this species the cutest of the arachnids. They also seem apprehensively interested, frequently carefully surveying nearby humans before retreating into a hiding place.
The one exception to this is the Brazilian Wandering Spider, which has been known to bite humans. These spiders are only dangerous if they feel their lives are in danger. They generally shy away from close contact. Because of their low toxicity and tiny fangs, they may fail to penetrate the skin. If you squeeze, trap, or crush them, though, they will bite.
