Black Widow Spider

Araneae: Theridiidae, Latrodectus mactans

The bite of the female black widow spider may not always be felt at first and besides slight local swelling, there is usually little evidence of a lesion. Two tiny red spots can sometimes be observed in the center of the swollen area. Most of the time, pain at the site of the bite occurs immediately and becomes most intense after about three hours. An overall aching of the body, especially in the legs, is a common reaction. Headache, elevated blood pressure, nausea and profuse perspiration may occur in severe cases. The condition is self-limiting and in most cases symptoms disappear in two or three days. Calcium gluconate is used intravenously to relieve and relax muscle spasms produced by black widow venom.

Be very careful when working around areas where black widow spiders may be established. Take proper precautions, wear gloves and pay attention to where you are working. Black widow bites are sharp and painful, and the victim should go to the doctor immediately for treatment.
