I checked my best hive today.
I have not treated this hive
for 7 weeks or so due to anticipated honey harvest.
I have not cleaned the bottom board for about the same amount of time. Two week Mite count on July 15 was 6.
I pulled the SBB (white cardboard) and used my magnifying glass and good reading glasses and found 40 -50 mites in the thick debris...that is an 8 week count. I have not treated for a few months due to honey. I fogged in May, June and early july. I have nearly no mites in the other two hives where i fogged a few more times in Aug and Sept. Do i have a major mite issue here??
