Home Care

Home treatment depends on the location of, and reaction to, the sting.

For mild stings, place ice (wrapped in a clean cloth) on the bite area for 10 minutes and then off for 10 minutes. Repeat this process. If the person has problems with blood circulation, decrease the time to prevent possible damage to the skin.

Some people are allergic to fire ant venom. If the reaction is severe, seek medical help right away and call your local emergency number (such as 911) or poison control.
