(HealthDay News) -- Most spider bites do not fully penetrate human skin, so they tend to only cause a mild reaction.
But if the bite is from a brown recluse spider or a black widow, it will cause a much more serious reaction that requires immediate care, the Nemours Foundation says.
If you suspect a spider bite, wash the area with soap and water, apply an ice pack or a cool wet cloth to relieve swelling or pain.
To help prevent spider bites, keep garages, attics and woodpiles free of spider webs. And all family members should wear long sleeves and pants in areas with an abundance of spiders.
Nemours suggests seeking medical care immediately if:
- There are signs of an allergic reaction, such as a rash, itching or swelling.
- There's a patch of skin that appears infected.
- You suspect a bite from a brown recluse or black widow.
