Re: Is entrance reducer neccessary?
I don't like the idea of going inside the hive to place and remove wire mesh to reduce the entrance. I have five 1" holes on each of my TBHs and I plugged three of them on each to reduce the cold coming into the hive. The holes are about 2 1/2 ft. off the ground, and though I've had mice problems with my Langstroths, mice didn't seem to attempt to get into the TBHs. If you feel wire mesh is a must, I'd tack a piece over the holes on the outside so you don't have to open the front of the hive and move comb (likely with brood) around in the cold weather in order to give the bees their full entrance.
If I'm neither sanguine, phlegmatic, choleric, nor melancholy, does that mean I'm out of humour?
