Local Skin Reactions to the Sting

• The main symptoms are pain, burning, swelling and redness at the sting site.
• Pain and burning at the site usually lasts 10 minutes. The pain is far less than that of a bee sting.
• Itching follows the pain and can last for weeks.
• Hive. Hive-like bump occurs at sting site within 30 minutes (100%). This looks like a red spot with a raised, white center.
• Pimples with yellow fluid (pustules) occur at the sting site within 24 hours (96%). These pimples are almost diagnostic for fire ant stings. They are very itchy. They usually open on their own by 3 days. Then, they dry over. Sometimes, they can last for up to a week.
• Normal Swelling from venom can increase for 24 hours after the sting. Stings of the upper face can cause severe swelling around the eye. This is harmless.
• Severe Swelling. Sometimes, fire ant bites can cause severe swelling. Hand or foot bites can cause swelling that crosses the wrist (or ankle). The amount of swelling can limit movement and need treatment with steroids. These do not carry an increased risk of allergic reaction with future stings.
• Redness. Stings can become red. This is normal. That doesn't mean they are infected. Infections rarely occur in stings.

Anaphylactic Reaction to the Sting

• A severe life-threatening allergic reaction is called anaphylaxis.
• The main symptoms are hives with trouble breathing and swallowing. It starts within 2 hours of the sting.
• This severe reaction to fire ant stings happens in about 1% of people who are stung.
• Hives. After fire ant stings, some people just develop hives all over or face swelling. Hives or face swelling alone may be able to be treated at home. But, at times, these symptoms can also lead to anaphylaxis. Be sure to call your doctor now to help decide.

Cause of Fire Ant Sting Reactions

• The ant's stinger injects venom into the skin.
• The venom is what causes all the symptoms.
• A fire ant attaches to the skin with its jaws and swivels its body. It stings multiple times with its back stinger.
• One fire ant can leave an arc of more than one sting.

General Info about Fire Ants

• In infested areas, fire ants cause many more stings than bees or yellow jackets.
• More than 50% of people living in these areas are stung each year.
• Fire ants are found throughout the Southern U.S., from Florida to Texas. They have also appeared in California, New Mexico and Arizona.
• Colonies of fire ants live in small mounds of dirt, usually 6 inches tall.
• When the mound is disturbed, hundreds of fire ants stream out and attack.
• The fire ant causes a "burning" feeling at the site of the stings. This is how it got its name.

Prevention of Fire Ant Stings

• The only way to prevent fire ant stings is to avoid their colonies (mounds).
• If you have been stung, move away from the area to prevent more stings
• Learn to spot their colonies (mounds) and to keep their distance.
• Insect repellents (including those that have DEET) don't help to prevent fire ant stings.
• Wear socks. Fire ants cannot bite through socks.

What You Should Know about Fire Ant Stings:

• Pain from a fire ant sting is less severe than with a bee sting. Most often, it's gone in 10 minutes.
• Fire ant stings form a pimple and become red. This is normal. That doesn't mean they are infected.
• If you have been stung, move away from the area to prevent more stings.
• Here is some care advice that should help.

Pain Medicine:

• To help with the pain, take an acetaminophen product (such as Tylenol).
• Another choice is an ibuprofen product (such as Advil). Ibuprofen works well for this type of pain.
• Use as needed, but do not take more than the maximum recommended dosage as stated on the packet.
• If you are not sure what to take, ask a pharmacist.

Pustules (pimples) - Do Not Open:

• By 24 hours, a small blister (or blisters) will form over the sting.
• Do not open them. If you do, they often become infected.
• Try not to scratch them.
• Left alone, they will most likely dry up in 4 days.

Antibiotic Ointment:

What to Expect:
