I decided to do an OAV treatment on all of my hives last week. I did not do a count on the front end to see what the mite load was. I figured OAV is supposed to be relatively harmless to the bees so I might as well. A couple of days after I treated I counted the mites under the screened bottom board and it was in the neighborhood of 100 dead mites on one hive. After the second treatment the number did not change much at all. Is this a high or low number for 2 brood boxes that are fairly well packed to the gills?
