I monitor varroa using a bottom board count. Last season i treated with Formic Acid when numbers started to climb in August. I harvested some honey in June and the bees seemed more easily riled than before and I did not check for varroa this year until early September due to being away. I saw one live mite and about a dozen dead ones with missing legs and punctured carapaces. I do not remember seeing dead mites in previous counts. In short my bees are more aggressive but also more hygienic regarding varroa. As these are characteristics of African bees I believe I have an Africanized hive. This is OK as they are not that hostile and less management will be required. Does this make sense?
