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!

  1. Dusting your ankles and waistband and groin with powdered sulfur, which you can get from your pharmacist, before walking or camping in areas with chiggers, along with tucking the end of your pants legs into your socks, will greatly reduce chigger bites.

    People, calm down. Chiggers are the basic stuff. Ticks are the ones you have to worry about.

  4. Let me start by saying I am 42 years old. All my mother used when we were kids was fingernail polish and that is what I still use. It works every time never had it fail me yet.

  5. Can the chiggers get in your bed and on furniture even if you have showered?

  6. Dab the bite with the hottest water you can bear (without scalding yourself). I use metal tongs dipped in very hot water. This gets rid of the itch for several hours. And it’s free.
