I need some advise.
My new unit works like a speed bird. The bottom pipe exit proves to be very efficient and the 1.5" inside the bowel seems to keep more heat and speeds-up the heat recovery time.
I treated my hives last night from the back through my standard mid center 1/4" hole with 3 gram of OA. Before that, I took the entrance reducer out, swept all garbage out on the bottom board and installed my white cardboard trays to catch the mites and other debris. I installed the reducers again with the smallest opening free and opened the winter covers from the back and vaporized.
Since it was getting dark, I left the cardboard in till early morning and found no mites on the cardboard. Please don't ask if I did a pre-mite count, since I am not wasting 100 some bees now and open the hive up to do so.
Question is, should I repeat the treatment in four days?
The bees are flying very nicely now with 15-20°C in the day. I am feeding, but the bees take very little syrup or pollen substitute.
All the best, Joerg K.
