I am working on getting a meal worm colony going. I have done a lot of reading and things are going good. Been buying wheat bran in gallon amounts. Finally found a place where I can get 50 lbs of wheat bran for $10.00. Been reading about microwaving the bran to make sure there’s no mites in it. What are the possibilities of this happening? Are there other things that might be in the bran? Should I do the microwave thing? Thanks for any advice.
