When to Seek Medical Care
Some arthropod bites/stings are more dangerous than others. If a black widow or brown recluse spider bite is suspected, apply ice to the area and seek medical help. Symptoms of these bites include:
  • A deep blue or purple area around the bite, often with a surrounding white area and a red outer ring
  • Abdominal pain
  • Headache
  • Fever
  • Fatigue
  • Nausea
  • Muscle stiffness
If the site of a tick bite develops a red, swollen, spreading area, seek medical help to check for Lyme disease.

When dealing with stings, be sure to watch out for symptoms such as:
  • Hives, itching, or swelling in areas beyond the sting site
  • Swelling of the lips or throat
  • Tightness in the chest or difficulty breathing
  • Hoarse voice or tongue swelling
  • Dizziness or loss of consciousness
