I got a call a week and a half ago from a friend who is a supplier. He had extra packages of bees on the premises and asked if I wanted any. I took one because I knew the supplier from Texas. He also gave me a discount. I didn't realize that there wasn't a cork in the cage, just sugar candy. They released her but I didn't know when exactly. My friend said the bees had been treated for mites before the packages were made up. I decided to test anyway out of curiosity. Yup! 0 mites! Also tested other existing colonies and got 0 mites. I was feeling pretty good at this point, then I checked some drone brood and discovered a mite moving around with a drone pupae. :'(
