  • Two small puncture marks swell around the area.
  • You may observe a red ring may form around the pale center of the bite.
  • Usually, a white blister forms, and a lesion or ulcer may develop. The ulcer will turn blue-purple, and the center will be rigid and hollow. Some skin may peel off.
  • After this, the wound will usually heal; however, this can take several weeks.
  • Without treatment, in some cases, tissue death (necrosis) can occur.

These spiders tend to sting when we shake off their web. Bites in babies and children can be more problematic than in adults.
