Spider bite


A spider bite is an injury caused by venom from a spider's bite. In the U.S., only black widows and brown recluse spider bites are a threat. These spiders generally live in undisturbed areas, such as attics or sheds, and don't bite unless threatened.


Treatment usually includes cleaning the bite, applying ice, and watching for infection.
