Are Yellow Sac Spiders Venomous? Are They Dangerous to Humans?
Yellow sac spiders are venomous. The effects of their bites resemble those of the brown recluse and hobo spiders, although not nearly as severe. Plus, they heal more rapidly. Yellow sac spider venom is “cytotoxic,” which basically means that it kills cell tissue. The harm, however, is localized. The bite itself may feel similar to a bee sting. It will likely redden and get itchy, and it may result in a blister. On rare occasions, a small necrotic lesion may form. According to arachnologist Darwin K. Vest, “Systemic effects are usually not severe, but when they occur may include chills, fever, headache, dizziness, nausea, anorexia, and sometimes shock.” Again, these symptoms are in extreme case. Most people are left with an itchy bump that disappears within a few days. Although bites are fairly common, “sac spiders typically do not bite unless they are trapped against the skin or provoked,” says Dr. Jones. How Does One Remove Yellow Sac Spiders from Dwellings?
