Fire Ants

Fire ants are extremely aggressive when bothered, and they may sting repeatedly. When stung, people may also experience itching, followed by the appearance of a white, fluid-filled pustule. Sensitive people may also have swelling, chest pain, difficulty breathing, nausea, and sweat after being stung. If this happens, get emergency medical treatment immediately. You can dial 911, or reach a Poison Control Center by dialing 1-800-222-1222.

Fire ants were introduced into the United States in the 1920's and 1930's. Now they are considered an invasive species in the southern states from Virginia to New Mexico, as well as California and Puerto Rico. Therefore, all areas where fire ant activity has been reported are under a quarantine regulated by the USDA.
