The yellow sac spider is a smaller spider species which also possesses venom reported to cause necrosis in victims. While these reports are anecdotal and likely unreliable, the spider bites do cause localized swelling and are unpleasant. The spiders are recognizable by their pale-yellow bodies.
Yellow sac spiders will live in human homes as well as gardens or forests. These spiders do not build webs to capture prey, relying on actively hunting and travelling to locate and capture small arthropods.
