1. Chigger identification

Chigger100x magnificationChiggers, or harvest mites are microscopic, reddish arachnids that usually cannot be seen with the naked eye. The larvae (babies) hatch in grass and foliage and attach themselves to anyone who gets close enough for them to climb onto. After finding a suitable host, the larvae attaches itself to a pore or hair follicle and injects digestive enzymes into the hole that promptly dissolve the surrounding skin cells which are then used for nourishment by the growing chigger. Once they've eaten their fill they release from their hosts, grow into adults and feed on plant matter on which they lay more eggs.

The bites themselves usually progress into super-itchy, raised red welts that can take up to two weeks to heal. Below you will find instructions for eliminating chiggers as well as reducing the effects of their bites.

2. Eliminating chiggers from your property

Chiggers are active during the warm season from spring to early fall. They can be found living in berry patches and bushes, tall grass and weeds, straw, leaves, fences, bark, and dense foliage.

Shelter and breeding grounds

Flood all remaining foliage with a mixture of soap and water to kill off adults and larvae. Repeat the flood once a week for a month to get newly hatched larvae and you should have eliminated most of them.

If they've made it into your houseplants, move them outdoors and kill the adults and larvae by soaking them with a mild insecticidal soap that is labeled as safe for edibles or houseplants. Keep the plants away from people and pets and repeat the rinse weekly for four weeks.

3. Chigger treatment and prevention

catIf a person or pet becomes infested with chiggers, it's important that you wash them as well as their clothing at the same time. Otherwise larvae that hadn't yet made it to the skin can stick around for another chance and once they feed, they will drop off and head for the nearest houseplant.

Repellents

When traversing a potentially infested area, try not to move through dense foliage or sit on the ground. Following are some additional preventative measures:

Protective clothing

The most protective clothing you can wear is tight-knit, loosely fitting garments that leave no exposed skin for a chigger to latch onto. Wear your shirt and socks over your pants along with shoes that do not have open ventilation holes. Bathe and wash all of your clothes on the hottest setting with detergent immediately upon returning.

Sulfur powders

Sulfur powders available at your local drug store work well as a chigger repellent. Apply in and on your clothing and shoes before heading out. A powder puff makes application much easier.

Insect repellents

Insect repellents containing DEET (Diethyl-m-toluamide) are effective at repelling chiggers. Apply these to your clothing, not to your skin or to your pets. Be sure to use on your shoes, pant legs, waist, shirt and sleeves.

Citronella oil based products

Citronella oil is derived from citronella grass. It is used in perfumes, soaps, and insect repelling sprays, candles and tiki torches. These are marketed mainly as mosquito repellent but also repel chiggers.

Chigger removal

If you think you've just become host to a gang of chiggers, immediately wash all of your clothing with detergent and on the hottest setting - then wash yourself with plenty of soap and hot water. An exfoliating pad can be used and special attention should be paid to warm, moist areas (inside of knees, groin, anus, waist, armpits, neck, between toes, etc).

Chigger bites

Chigger bitesChigger bites are insanely itchy and swell into raised red welts that can last for a couple of weeks before subsiding. As difficult as it may be, resist scratching these bites - they can become infected. Instead, apply something that will limit their exposure to air. Several possibilities that people have reported success with are:

  • Clear nail polish
  • Green tea extract
  • Calamine lotion
  • Hydrocortisone cream

      As soon as you notice red bite use antibotic ointment on daily and the area clears up with in a few days to a week. Also keeps the bites from getting infected.

    2. John Henderson Says:

      One of the greatest misconceptions about chiggers is that they burrow into our skin and eventually die within the tissues, thus causing the persistent itch. This widespread myth has its origin in the southern states where pests with similar names such as jigger flea or the chigoe do attack by burrowing under skin. Chiggers are not equipped to burrow, and they are much too large to enter through the pores.

      If chiggers do not burrow under skin or drink blood, what are they doing that itches so much? Chiggers do bite us, much like ticks do. Chiggers attach by inserting minute specialized mouth parts into skin depressions, usually at skin pores or hair follicles.

      The chigger’s piercing mouth parts are short and delicate, and can penetrate only thin skin or where the skin wrinkles and folds.

      That’s why most chigger bites are around the ankles, the back of the knees, about the crotch, under the belt line and in the armpits. The insertion of the mouth parts is not perceptible. The bite alone is not the source of the itch.

      The reason the bite itches so intensely and for such a long time is because the chigger injects saliva into its victim after attaching to the skin. This saliva contains a powerful digestive enzyme that literally dissolves the skin cells it contacts. It is this liquefied tissue, never blood, that the chigger ingests and uses for food.

      A chigger usually goes unnoticed for one to three hours after it starts feeding. During this period the chigger quietly injects its digestive saliva. After a few hours your skin reacts by hardening the cells on all sides of the saliva path, eventually forming a hard tube-like structure called a stylostome.

      The stylostome walls off the corrosive saliva, but it also functions like a feeding tube for the hungry chigger. The chigger sits with its mouthparts attached to the stylostome, and like a person drinking a milk shake through a straw, it sucks up your liquefied tissue. Left undisturbed, the chigger continues alternately injecting saliva into the bite and sucking up liquid tissue.

      It is the stylostome that irritates and inflames the surrounding tissue and causes the characteristic red welt and intense itch. The longer the chigger feeds, the deeper the stylostome grows, and the larger the welt will eventually become. The idea that the welt swells and eventually engulfs the feeding chiggers is also a myth. Many people have seen a small red dot inside a welt (usually under a water blister), but this is the stylostome tube and not a chigger body.

      Does anyone know how long they will live on a sofa? When can I sit on it again? A bunch got picked up outside and transfered to the sofa before we realized they had been picked up.

    4. Herman C. Van Devander Says:

      I scratch the spot with my fingernail until it really starts itching, then I apply Mentholatum to the spot, and rub it in with pressure for about 30 seconds. The itching stops immediately and never returns.

    5. KansasMom Says:

      Okay, after reading so many responses I was ready to try some. I tried what I had handy first - the glue. I used elmers glue stick. Ahhhh, relief. It is easy to apply, washable, and doesn’t smell. I hope this relief lasts. (I got an anti-itch lotion and i work really well but smells a bit like urine and so don’t want to wear it to work!) I think chiggers are hateful little buggers. I never even heard of them till I got them. Guess now I have to go strip all the beds, vacuum the cars, wash all the clothes - ugh! So much for my tanned legs - now they are so bumpy I’ll be wearingpants for weeks according to “you guys”.

    6. Jesse Says:

      AVON ACNE OVERNIGHT BLEMISH TREATMENT

      Provides amaaaaazing burn and itching is gone.

    7. Jesse Says:

      I had an allergic reaction to the bites. they swelled and turned into blistery looking welts. I tryed everything for a day and medatated. but could not resist after 2 days of rediculous itching. So i took a cold bath and went to town. The pain was intense stung for a good hour then no more itchyness. I’ve been keepng the bites/scrapes clean, but they are still oozing disgusting clear and yellow liquids. I tryed getting drunk as a skunk to get my mind off but i cant do that everyday.. i gots things to do u know?

    8. Doug Cornett Says:

      I used Burt’s Bees body lotion and the itching stopped almost immediately. The big red welts were reduced to a small red spots by the next morning.

    9. Chiggers all over. Says:

      Apply rubbing alcohol to the bites, this will help you relieve the terrible itching.

    10. magdalena LiVolsi Says:

      I accidently scratched my little bites on my ankles..
      and then I applied salt. Yes/ it stung…but the salt drew out anything that was either alive or itching.

    11. Johnny Says:

      Prunella Vulgaris/Jewelweed Salve works as a great heal all for many skin irritations. I buy it online at an herbal store in Tennessee along with poison ivy products that also work extremely well. I haven’t dealt with chiggers in years but the salve gets you healed and stops the itch. Good luck!!

    12. young Says:

      hydrogen peroxide makes it sting like hell but works.

    13. cody Says:

      Some other good ways to get rid of them is to put a steak where you were bitten.If nail polish and steak doesnt work the best way to get rid of them would be to have a doctor get rid of them.

    14. kathy Says:

      I just got back from camping and it looks like chigger bites. Itches like crazy. Had my husband rub my back with Calamine lotion before goingot bed. It seemed to help. I will try anyting. I also tried the Avon Skin so Soft. I now have some repellent that th emilitary uses when they go ot the field.
      Thanks for all the tips.

    15. Deborah Waters Says:

      By accident I found that finger nail polish remover also works well on chigger bites. But there are some places on your body that you may not want to apply this to. It not only takes away the intense itching but also kills them.Please let me know if this was helpful to anyone. Good Luck!!

    16. Stacy Says:

      There is a simple solution to getting rid of chiggers and sand fleas. It’s called baby oil. My husband has been afflicked before and used hairspray, but that didn’t work as well until the baby oil. We’ve been to the beach many times and if you are covered with sunscreen they normally do not get a chance to get into your skin. At night, after a shower, cover your skin with baby oil. Do this daily while at the beach and you should remain chigger and sand flea safe. It keeps them from getting oxygen and spreading and keeps our pores filled. Unfortunetly, I just went to the beach and forgot the baby oil. I got sand fleas during the rain. I am now home covering myself with the baby oil and they are going away and I am not experiencing any itching. A simple preventative and cure that is inexpensive.

    17. allen Says:

      Listerine seems to relieve the itching and help cure the bites. I shower and slather it on before bed. It’s a little sticky but the itching stops. I can take the sticky part. I understand that clear nail polish and the like is not effective since the little buggers seem to travel on the skin. Don’t know for sure. Too bad there isn’t a definitive treatment.

    18. Mark Says:

      We live in an area where chiggers have been a fact of life since youth. We grew up using a dab of clear fingernail polish on bites and then putting up with them until the itch gradually subsides.

      After reading all I could find, I found what works best for us, is as follows.

      NOTICE: Common sense must be applied here. Acetone is harsh on skin and removes all of its oils. But its risk or affect is nowhere near the discomfort of the relentless itch of chigger bites. Acetone also bleeds colors, which is why I use a white wash cloth. (So do not spill any on colored materials or clothing. Some plastics are also degraded, so care should be exercised in what is contacted by it.

      Other than that, this method instantly kills the bug, stops the itch, and begins the healing process with a single application.

      1. Carefully pour some Acetone on a white wash cloth in a fair amount - but not so much it will drip off when used to wipe the bite area.

      2. It will feel very cold, but rub the folded cloth on the bites back and forth 3-4 times, with only using pressure similar to what you would apply if scrubbbing with soap in the shower - and no more.

      3. Be sure you get them all - sometimes more bites can become apparent later on - even a day after initial detection. Same method applies.

      4. Put away the Acetone and get out some Camphor. I used some “essential oil” Camphor I had stored away, but if you find any product rich in the oil it should work as well (provided it is contained in a base that will hold it in place).

      lightly massage the oil in a generous amount on each bite site and leave an extra dab on each bump.

      5. You’re done. Itching will stop totally. You will get nearly 100% relief for at least 9 hours. If some itch returns at nite or after perspiring, try the camphor alone (unless you are certain the Acetone is justified).

      Personally, one application as indicated above works for me, but some residual itching may re-occur since the chigger’s secreted enzyme causes an allergic-type reaction, which must fade over time.

      However, if it does linger or return - it will not be anywhere close to the former itching intensity and will gradually subside within a short time. Repeat Camphor application if desired, but as I said, I usually don’t need to.

      FYI - my exposure is typically a minimum of 12 bites. This happens despite using precautionary measures before becoming a host.

    19. tom everson Says:

      There is only one thing I have found that helps with chigger bites. The best way to prevent them is clothes tucked in with bug spray and Shower after exposure but if bitten running hot water over the bite for a few seconds until you can’t stand it will stop the itching for about 4 to 6 hours.
