I use Carmex on the bites! My sister who has them in her yard, keeps half and half Bleach and Water that she dabs on chigger bites.
I don't care what they are, or what they look like, all I know is that everytime you touch the bite area, they flare up again! They can itch for a week! Carmex seems to reduce the inflamation and itch for me so they only last a couple days! I don't like the little suckers!
