Anyone experiencing high varroa numbers this winter? I used Apivar in the autumn after taking the honey off and then looked at the drop rate in December which was alarmingly high. An oxalic acid trickle treatment in January gave a drop of over 200 but drops are still high (8 per day). I wonder if brood has been present throughout the mild winter giving the mites somewhere to hide. Whats others drop rates like?
