Bleeding also may occur with a bite. Signs of a bacterial infection due to a spider bite occur infrequently (0.9%). [9] A study of 750 definite spider bites in Australia indicated that 6% of spider bites cause significant effects, the vast majority of these being redback spider bites causing significant pain lasting more than 24 hours. [10]
However, most bite victims suffer only local pain and bleeding, a few more have limited neurotoxic symptoms (tingling, racing heart, more widespread pain), and there have been several recorded bites by this spider producing severe symptoms requiring medical treatment. [37] There are no recorded human fatalities due to mouse spider bites.
There have been documented cases of homes having very large populations of brown recluse spiders for many years without any of the human inhabitants being bitten. For this reason, L. reclusa bites are relatively rare, but, because its range overlaps human habitation, its bite is the cause of loxoscelism in North America. [citation needed]
The hobo spider and the yellow sac spider have also been reported to cause necrotic bites. However, the bites from these spiders are not known to produce the severe symptoms that can follow from a recluse spider bite, and the level of danger posed by these has been called into question. [40] [41]
Medically significant spider bites involve substantial envenomation from only certain species such as widow spiders and recluse spiders. Symptoms of latrodectism (from widow spiders) may include pain at the bite or involve the chest and abdomen, sweating, muscle cramps and vomiting among others. By comparison, loxoscelism (from recluse spiders ...
Two venomous spiders, black widows and brown recluse spiders, can cause severe symptoms, experts say. Here are spider bite pictures and tips to identify them.
A bite of Latrodectus may not inject any venom (known as a dry bite) and so no illness occurs. About 75% of "wet" bites will have localized pain and nothing more. [1] If, however, there is a substantial dose, a bite can cause latrodectism. The main symptoms are generalized muscle pain, stomach cramps, nausea and vomiting.
The symptoms of a bite are typically similar to a bee or wasp sting. However, the bite of Steatoda nobilis, along with others in its genus, can also produce a set of symptoms known as steatodism. [12] These symptoms include intense pain radiating from the bite site, along with feverishness or general malaise. [33]
