Black Widow Spider Danger

Female black widow spiders attack humans when they are disturbed. The venom of the black widow spider is nearly 15 times stronger than that of a rattlesnake and is comprised of neurotoxins that affect the nervous system. 

The bite of the black widow is only mildly painful. However, within a few minutes, 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 paralysis and delirium. Other general symptoms include restlessness, panic attacks, heavy breathing, difficultly speaking and profuse sweating. Symptoms typically diminish within two to three days. However, some symptoms may continue for three or more weeks after recovery.

Harm inflicted by the black widow spider is potentially fatal. The young, elderly and those with high blood pressure are particularly susceptible to fatalities. Deaths caused by black widow spider bites are typically the result of respiratory paralysis. However, fatalities from untreated black widow spider bites are uncommon, comprising approximately five per cent of all documented black widow attacks. If promptly and properly treated, victims can achieve full recovery within five days.
