Because chigger wounds are a complex combination of enzymatic and the resulting mechanical damage, plus allergy and immune responses, plus possible secondary bacterial infection subject to local influences, no one remedy works equally well for most people.

The chiggers' digestive enzymes in the saliva cause "the insanely itchy welts".
The itching can be alleviated through use of over-the-counter topical corticosteroids and antihistamines.
According to Mayo Clinic, the chiggers "fall off after a few days, leaving behind red, itchy welts", which normally heal on their own within one to two weeks.
Hot showers or baths also help reduce itching.
In cases of severe dermatitis or secondary infection associated with chigger bites, a doctor should be consulted.


According to an Ohio State University Extension Fact Sheet: 
... After returning from a chigger-infested area, launder the field clothes in soapy, hot water (125°F.) ...
As soon as possible, take a good hot bath or shower and soap repeatedly.
The chiggers may be dislodged, but you will still have the stylostomes, causing the severe itch.
Scratching deep to remove stylostomes can cause secondary infections.
For temporary relief of itching, apply ointments of benzocaine, hydrocortisone, calamine lotion, New Skin, After Bite, or others recommended by your pharmacist or medical doctor.
 ... (The sooner the treatment, the better the results.)

Home remedies to "suffocate" the mite, such as applying clear nail polish, rubbing alcohol, or bleach, may have little benefit since the mites do not burrow into the skin.
However, since the mite may still be attached for up to 3 days, these treatments could possibly kill the mite, reducing further damage.
