I am so grossed out right now. I went to refill my chickens food and found grain mites everywhere!!! I keep the 50 lb bag in the basement and a large pitcher of feed next to the back door to refill the food. I refill the pitcher when it runs out. I see mites all over the pitcher and the bag. Im going out to buy new food now but I would really appreciate some advice on how to store feed so it won't become infested with these nasty things. I was thinking air tight containers but where would I find an air tight container to fit 50 lb of feed. Also doesn't help that it's my parents house and I can't have them find out. Also how do I get rid of them and make sure they don't get into the new bag. The old one will be thrown out
