Signs and Symptoms of Brown Recluse or Black Widow Spider Bites:
- Deep purple or blue area around the bite, surrounded by a whitish ring and a larger outer red ring
- Swelling or redness around the bite
- Joint stiffness or pain
- Muscle spasms, tightness, and stiffness
- Body rash
- Abdominal pain
- Pink or reddish urine
- General feeling of sickness
- Lack of appetite
If bitten by a spider (other than a brown recluse or black widow) and don't seem to be having an allergic reaction:
- Wash the bitten area with soap and water.
- Apply an ice pack or a cool wet cloth to the bite to relieve pain and swelling.
- Elevate the area to slow the spread of venom.
Seek emergency medical care if:
- There are any signs of an allergic reaction
- Any kind of rash after a bite develops
- The area begins to look infected (increasing redness, pain, swelling, warmth, or pus)
- You think you were bitten by a brown recluse or black widow spider
- Insect repellents are useful, but use one containing 10% to 30% DEET. Make sure that garages, attics, and woodpiles are free of spider webs, and that you wear long sleeves and pants while in the areas.
