I've tried 'em all and have found out one truth. There is no good home remedy for chiggers. None of 'em work. All you can do is tough it out.

Sitting in a tub of hot water - bleach or no - will help with the itching, at least for a few minutes. Taking benedryl will help with the itching too.

No scratching allowed, for sure! Scratching only makes it worse. Getting hot and sweaty is the worst thing in the world to do when you got chigger bites, so I hope he can stay indoors under the AC until things calm down a bit.

If he scratches and the bites start oozing, treat 'em with hydrogen peroxide. They'll still itch like the devil, but the HO will dry up the wound and keep it from getting infected.

If it's real bad, take him to the doc and see if he can get a cortisone shot.
