Anyone have any experience with grain mites in feed? I just bought a bag of medicated chick crumbles, by Purina two days ago. Just a little while ago I went to top off the feed dishes and noticed what I thought was dust on the clip I use to keep the bag closed. I looked closer and the "dust" was moving--little white microscopic buggy things. Immediately I freaked out. DS looked it up online and found it is probably "Grain Mites". Does anyone know if I can put the bag of food in the freezer or will it affect the medication or the feed? I assume freezing will kill the little buggers? Now I am feeling itchy and really needing to take a shower! I also assume from what DS read, that they will not harm the chicks or people? I have 5 week olds and newly hatched chicks I just put in the brooder tonight.
