What are the symptoms of spider bites and are they dangerous?

Depends: This depends on the type of spider bite and ranges from simple wound care and cleaning to Antivenin administration for latrodectus (black widow) bites to surgical debridement for an extending severely necrotic loxoceles) recluse genus) bite.

Painful red spots.: Most spider bites are single or sometimes clustered small red raised spots, but can vary in size and severity. Some spiders can leave a quarter or larger sized lesion that takes a week or more to heal. The black widow and the brown recluse are in a class all their own. Envenomation by them is not subtle.
