A black widow spider is recognized by a red-orange hourglass-shaped marking on the underside of its belly. Its bite may be painful or may not be noticed.

After a bite, symptoms that may develop are:

  • severe muscle pain and cramping
  • high blood pressure
  • weakness
  • difficulty breathing
  • headache
  • nausea
  • vomiting

Symptoms usually begin within the first three hours.
