Mites are increasing
In testing (drop and sugar roll) I have found that the mites are increasing in my hives. I am now increasing my fogging schedule to 2 times a week. I am using FGMO/Thymol. I think my bees are robbing my neighbors hives and he does not treat at all. They are new at beekeeping and don't want to learn. I'm sure they will lose all 5 of their hives this winter because they only are 1 hive body high.
