Many factors like location on the body, temperature, season, body size of the victim, depth of the bite and amount of venom injected affect severity of reaction to a Black Widow bite. Bites often produce a rapid sharp pain like a pin prick and then disappear rapidly. Black Widow bites can be fatal to children and elderly victims and medical attention should be sought for anyone suspecting a Widow bite.

Black Widows are not aggressive and the rare defensive bite occurs from sitting on the spider etc. Anyone suspecting a Black Widow bite should try to capture the spider to take to the hospital for positive identification. An anti-venom specific for the Black Widow spider bite is readily available to most physicians. Male black widow spiders are harmless to humans.

What Does Black Widow Venom Do?

It is reported that the Black Widow’s venom is more potent than rattlesnake venom. To feed, Black Widow spiders puncture their prey with fangs and inject digestive enzymes into the corpse. These enzymes, liquefy their prey’s bodies and then the spider sucks up the resulting fluid for a meal.
