I am trying to breed my own feeder rodents and insects. I work in a pet store and I brought some rodent block dust (the kind you find a the bottom of the bag) to feed to my crickets and other insects. Little did I know, the dust was infested with grain mites. I threw out my entire mealworm colony and my entire dubia colony. Thankfully they were still small and I didn't lose much. I was able to save my super worms and moved them to another room. I haven't seen grain mites on them since but I will check again today.

I recently bought another starter of mealworms and a dubia starter and I haven't set them up yet (got the dubia today). I went in to do a thorough clean of the reptile room (where we keep rodents and reptiles) just now and found half the room is infested! The closet where we kept the insects previously and the rodent racks are all covered. They cover the water bowls and tanks of my two leopard geckos and cover the water bottles of my rodents and all the wood is covered. We checked their container of food and we didn't see any mites anywhere. It was kept on the other side of the room. We've removed the food and we are starting to remove tanks and bottles to wash them thoroughly with hot water and soap. I'm going to wipe down every surface but I really don't know what to do. I thought they were gone when we removed the insects and infected grain. Their current food isn't the source but they've infested the rat racks and mouse cages. I just really don't know how to get rid of these.
