6 Home Remedies for Fire Ant Bites

6 Home Remedies for Fire Ant Bites | The Survival Doctor

If you disturb fire ants, they don’t mess around. They attack. Technically they bite and sting. When they bite, they clamp to your skin with their two strong pincers. Because of this it takes a lot of vigorous brushing to get them off. After biting, they sting by swinging their tail to and fro. One biting fire ant can sting you six to eight times.

Having grown up in the South, I’ve been bitten enough times by fire ants to pretty well know what’s going on before I see them. I know when I feel that distinctive sting (it’s like being touched with a hot match head … for a long time), I’m going to find a lot of creepy, crawling dots.

Because fire ants don’t come as singles. They quickly cover a foot, leg, or arm before you know what’s happening. And the little devils don’t leave easily. You have to brush and brush and often take off some apparel to make sure they’re not clinging to that. And I know they’re going to leave a sore, itching spot I’m going to have to deal with for days.

Although potentially killer allergic reactions occur, just as they do in bee and wasp stings, I’ve never seen one. But I have seen people with so many stings they literally get sick, and if it’s an arm or leg, there can be lots of local swelling.

We who’ve been bitten all have our little tricks on how to treat fire ant bites, so let’s dig right in.

How to Treat Fire Ant Bites (and Stings)

Home Remedies

  • How to Treat Fire Ant Bites | The Survival DoctorIce pack (with a cloth between the skin and pack) or a cool, wet cloth—or anything cool. Apply for 10-minute intervals with a break in between.
  • Paste of baking soda and water
  • Vinegar
  • Paste of baking soda and vinegar
  • Meat tenderizer
  • Wet tobacco (hopefully you don’t have any, but if you do, put it to some good use)

Oral Medicines

  • Antihistamine, such as diphenhydramine (Benadryl) or one of the nonsedating ones.


  • Epinephrine. Fire ants can cause the same type of life-threatening allergic reaction as wasps and bees. (See the next section on anaphylactic shock.) And there’s nothing that works as well for life-threatening reactions as injectable epinephrine. It comes in an easy-to-use, pen-like container with a retractable needle called an EpiPen. You can inject yourself or someone else. There’s also a smaller-dosage container you can get for small kids. Read the instructions beforehand, and use immediately if there’s a severe allergic reaction. Everyone should have one of these at home and one in a backpack or bug-out bag because when you need it, you need it immediately. But you’re going to have to ask your doctor for a prescription.
Anaphylactic Warning Signs
6 Home Remedies for Fire Ant Bites | The Survival Doctor

You’ll find fire ants, of course, in their nests (large mounds of dirt) but also on trees, feeding on dead things, and even on top of water.

They’re the same as in any severe allergic reaction—tightness in the chest, trouble breathing, severe nausea, or a breakout of welts over the body (including areas that have not been stung).

If you have these, call 911 or get to a doctor ASAP. If you can’t, the same suggestions apply as for any anaphylactic reaction. (See my post on bee stings for more details.)


Now don’t think these ants are satisfied with what they’ve got. These biting invaders first came to the U.S. in 1939 on a South American ship anchored in Mobile, AL. They quickly spread throughout the Southeast, into the Southwest and California, and along the Atlantic Coast. And now they’re moving northward, wiping out other ant types as they go.

What about you? Have you ever made a fire ant mad? How did the sting feel? What did you do?

    So my sons (age 14 and 9) got fire ant bites (both red and black) last summer/fall (6-8 months ago). The bites went their normal course: itchy with the tell-tale pustule, swelling, and then healing. However, there are small bumps still there on neck and legs and hands where the bites were. They don’t hurt or cause any problems, but they don’t seem to be going away and are a little unsightly. Is this common? We are new to the southern states and have never dealt with this. Will they ever go away? They are about the size of the original pustules, but just skin colored and not infected or anything.

    • James Hubbard, MD, MPH

      That’s not typical. I’d ask their doctor to check them next time they go in.

      • Karen R.

        Thanks, I will do that!

    We use toothpaste with fluoride like Ultrabrite on the bites but you have to get it on there quickly after being bitten. Usually, it won’t even make a blister and is barely red the next day.

      Thanks, Marie.

    First, and I’ve seen it all over the Internet today not to mention all my life, fire ants do not bite. They sting. With stingers. In the back end like wasps and bees and hornets. They can sting repeatedly, unlike common honey bees, which can only sting once and embed their stinger and then die, fire ants can and will go on and on and on as will its brothers and sisters, all at the same time. What can happen, and does, is that the individual stings once and gets his pincers locked in, then he circles around using that first “breakfast location” and circles around with his back end stinging as he goes. From that point of view he could make the circular pattern that is seen with the biters with which they are compared today. Second, and this is from my own life, my experience with fire ant stings is is to scratch that head off as soon as it starts to itch. I only ever had two that I treated “by the book” and both of them resulted pock-like scars. that I still carry forty years later. The other stings I have had apparently did not leave scars, because I don’t know where they are. It is my belief that whatever poison they carry they carry in their tails to make you itch is also just enough to destroy the flesh where they sting you. Just my thought. No science to go with it. Except those two pockmarks on my leg.

      I just got my first fire ant stings 4 days ago and opened all of them as I found the pressure build up hurt when lightly touched. I then squeezed out all the fluid in them, washed with hydrogen peroxide and let air dry. They are mostly barely visible now and do not hurt.

    Nothing works except avoidance and time, once bit these things ooze and itch for a month.

    My husband and I went to bed on Friday night at just past 11:00; Saturday morning at 8:00 I walked into the dining room and there were hundreds of ants scaling a wall. Just around the corner was a 3″ mound (inside the front entrance). I had no idea what kind of ants they were and bent over to lift the carpet away from the baseboard–and was swarmed on both hands and arms. Exterminator came quickly and killed all the little buggers inside our house and out in the yard, but I am covered in bites/stings, blisters, and feel very sick. Came on here to find a solution for the itch/pain; does anyone have something for sick feeling? I need to be able to work tomorrow.

  • Debbie

    Is it normal to still have the bites weeks later? They still itch on occasion also.

    • James Hubbard, MD, MPH

      They should have gone away within a week or two, and no new ones occurring.

    I live in Florida and we just had a day of hard rain that washed away all the fire ant mounds so it was hard to tell where they were. I was outside with my two kids and my one year old apparently stood right where a mound was, with all the ants swarming around on the ground trying to repair their mound. Before I knew what was happening he had several hundred bites! The thing about fire ants is they wait until their fellow ants are all over you before the first one bites, then they all start biting at once. But several hundred bites, that I the most I’ve ever seen! I had to strip his clothes off right there to get the little bastards off him ASAP. A few even got into his diaper! He did not get sick though and barely any swelling at all. He’s not even itching them much. He acts like nothing happened, didn’t even cry afterwards. This is one tough kid!

    • James Hubbard, MD, MPH

      That’s scary. Be sure to watch him closely and have him drink plenty of fluids. One explanation on not much of a local reaction could be if that’s the first time he’s been bitten. The body often has needs to have been exposed at least once, sometimes more, before mounting any allergic reaction. And of course, he sounds very tough.

      • Noneya Biness

        By the end of the day yesterday the bites were looking like they would subside, but then today they all have big white raised bumps on each one. I got bit by one too when I was cleaning him off and the same thing happened. It doesn’t itch much, but the white bumps look terrible. It does look like he has a slight amount of swelling in his hands where the most bites are and his skin is warm in those areas. Luckily the ants never made it to his face or torso. When I realized what was happening all the ants had moved to the outside of his shirt and were biting his shirt. He still looks worse than any fire ant bite images I’ve seen on the internet. I counted 60 bites on just his left hand.

        • James Hubbard, MD, MPH

          Thanks horrible, Noneya. Be sure to keep them very clean and, with that many on a young child, don’t hesitate to check in with your regular doctor.

  • Quinton

    I got stung in my upper thigh and the little booger actually worked it’s way up and stung my penis. I have swelling around the outer skin area. Should I see the doctor or will it be alright?

    • James Hubbard, MD, MPH

      Your call. Because the skin is looser there the swelling can be more but otherwise, usually it’s like getting stung anywhere else.
