Grain mites are....I just have no words.
The easiest thing to do, and there is no need to dump your colony, is to take the lid off the container and place it somewhere that it can dry out. I place my infested tray on a bench on the front porch and let the warm, dry breeze blow over it all day. (Avoid direct sunlight as that can cook the worms and beetles.) Then I bring it in and leave it to dry further overnight, and sometimes I place a fan to blow over it.
The mites will dry out and disappear as if by magic.
