Black Widow Spider Danger
Female black widow spiders can attack humans when they are provoked. The venom of the black widow spider is comprised of neurotoxins that affect the nervous system.
The initial bite of the black widow is only like a pinprick. However, within a few hours, extreme pain, cramping and nausea commonly occur. Pain and cramping can spread rapidly to the arms, legs, chest, back and abdomen. Swelling is often experienced in the extremities. In severe cases, victims may experience delirium. Other general symptoms include restlessness, panic attacks, heavy breathing, difficultly speaking and profuse sweating. Symptoms may diminish within two to three days. However, some symptoms may continue for much longer after recovery.
Harm inflicted by the black widow spider is unlikely fatal. The young, elderly and those with high blood pressure are particularly susceptible though. Most people recover with medical treatment which can include antivenin injections.
