The Sting of Fire Ants

Dr. Freeman says “Stay away!” Fire ants, like other insects, are most likely to sting if their homes are disturbed. Unfortunately, since some mounds are flat, mounds may be stepped on accidently resulting in hundreds of ants coming to the defense of the mound. Removing mounds requires killing the queen. Commercial products are available, but take several weeks to make the mounds disappear.

If your child encounters or accidently disturbs a mound, tell him or her to move away quickly; the longer you stay near a mound the more stings you may get.  Make sure your child wears closed-toe shoes and socks outdoors; avoid letting him or her go barefoot outside. When working in the garden or yard, wear work gloves. Shoes and gloves allow you the chance to get away from the mound and remove the shoes, socks and gloves with the attached stinging fire ants before they can reach your skin.

“The venom fire ants inject will kill bacteria and will kill some of your skin cells. This results in the formation of a blister that fills with a cloudy white material (dead cells) in about 24 hours. While this looks like a pus-filled lesion that should be drained, it is really sterile, and needs to be left alone,” advises Freeman.

If your child is severely fire ant allergic, carry an auto-injectable epinephrine device. Learn how to administer the epinephrine, and replace the device before the labeled expiration date.

Remember that epinephrine is a rescue medication only, and you must still take your child to an emergency room immediately if he or she is stung. Those with severe allergies may want to consider wearing a bracelet or necklace that identifies the wearer as having severe allergies.

Anyone who has had a serious adverse reaction to a fire ant sting should be evaluated by an allergist/immunologist, who will recommend testing to determine whether an insect allergy exists.

Your child’s allergist/immunologist will help determine the best form of treatment. People who have severe allergies to fire ants should consider receiving fire ant whole body extract immunotherapy, a highly effective (97%) vaccination program.

Patients who receive appropriate treat­ment such as immunotherapy and who practice careful avoidance measures can still participate in regular outdoor activities.
