Does anybody check for mites by doing the ether roll in a jar? I did one this weekend and found one mite on about 20 bees. I know I am supposed to test more bees than that, but I had trouble getting them to stay in the dang jar :) . Well, one mite on 20 bees doesn't seem like too heavy of an infestation, so I think I will forego any treatment this fall. I may do another roll in a week or two to see if I get similar results.
