How Do You Prevent and Treat Chigger Bites?



Red bugs, chiggers, berry bugs, scrub-itch mites and harvest mites are all terms used to describe members of the family of insects known as Trombiculidae. These reddish-orange mites can be found worldwide, but they really enjoy hanging out in damp, grassy and wooded areas, especially at the edges of forests.

In the United States, chiggers are mostly found in the southeast, south and midwest. They are most active from early spring to early autumn, until the first frost.


Chigger larvae infest humans by crawling up our shoes and legs as we make our way through the scrub.

What’s kind of cool is that chiggers do not actually bite us. Likewise, they do not burrow into our skin, and they do not suck our blood. Instead, chiggers use their mouths to drill tiny holes into our skin through which they secrete specialized salivary enzymes designed to break down our skin cells from the inside. Then, the chiggers slurp up the mixture through a tube formed by hardened skin cells called a stylosome. Basically, it’s like drinking a big “YOU” protein shake!

Your skin does not take too kindly to all of this drilling and parasitic digestion. Consequently, humans typically develop intensely itchy, bright red pimple-like bumps or hives or a generalized skin rash in the areas where the mites were attached, even up to 24 to 48 hours after exposure.

Chiggers prefer to attach to skin at areas where the clothing fits tightly against the body, such as at the tops of socks or around the elastic edges of underwear, so a rash in these areas may be a clue to the specific cause.


So, what can you do for a chigger rash? First, forget the old myth of applying fingernail polish to the affected areas. Chiggers do NOT burrow into the skin, so trying to suffocate the chiggers with polish makes no sense at all. Second, chiggers do not lay eggs in the skin, so stop worrying about that.

chigger-2Chigger wounds are a complex mixture of mechanical damage to the skin (the drilling), enzymatic disruption of the skin (the digestion), and your body’s own attempt to get rid of the parasite. Consequently, the most important thing to do is to prevent chigger infestation. Avoid camping in warm, moist temperate climates of high mammal density, including livestock pastures, with tall grass.

If the area is infested, get out of there quickly and wash your skin vigorously with soap and water. Itching is best alleviated through the use of topical corticosteroids (either over-the-counter hydrocortisone 1% ointment or prescription strength from your physician) and anti-histamines like Benadryl.

Watch out for severe chigger rashes that can become secondarily infected with bacteria; in these cases, consult a doctor immediately.

Now you know a “mitey” bit more about chiggers than you did before!

    As long as you use a insect repellant BEFORE you venture into yards, woods, or any other place they tend to show up..pine trees seem to be a hotspot..spray around the tops of socks and underwear…good luck!

    Finger nail polish remover (Acetone) is the quickest way that I have found to get relief. The enzyme has got to be killed to stop the melting of the skin. Stings like fire for a short time (minute or two), but well worth not having the prolonged itch for a week.

  3. My guys swear by Calamine lotion, the pink stuff. Worked better then all the other remedies they tried.

  4. Turmeric works great. Even just dusting on some of the culinary stuff from trader joes.

  5. Had them once really bad had no idea what they were as I live in the north and had never seen nor heard of them my doctor recommended kwell!!!Killed them on contact and no more itch.

  6. Witch Hazel! It is sold in a bottle and is also the active ingredient in Preparation H. Witch hazel on a cotton ball immediately calms the itch and helps speed up the healing process.

    I don’t know what this is the doctor told me that no one can catch it but my mother called it and she’s 90 years old I am so pissed at the doctor now I’m here trying to save everybody in the house if anyone knows anything I could do please write and tell me

  9. I use CHIGGEREX after they get me and “OFF” to help keep them off. Both seem to work.

  10. I had them all around my waist. I applied a OTC products made to get rid of them, much like fingernail polish. A friend applied it to places I couldn’t reach. When it dried I discovered that I had glued my underwear to my skin all around my waist! Ouch! It sure got rid of the red bugs along with patches of my skin! 😀
