Got a problem with my mealworm colony that is kind of gross. I don't think it's really affecting the mealworms other then using up all their food and water, but I seem to have had a mite explosion, I don't know what they are, meal mites or dust mites or grain mites or what. But there seems to have been a population explosion of these itty bitty little white mites in my mealworm colonies. How do I get rid of these things without killing off the mealworms too?
