I have two hives that both died this past year and I can't explain it. They were both doing well, until this past winter hit and then they just died. I noticed a mouse started to nest in one or both of them and started to forage on some of the brood that was left.
I have two friends who have hives in their houses and both would like me to trap them out! One is an old mansion where I can get up to it and place the remaining brood and honey close to the opening. We have a platform that I'm planning to use on top of the roof. I was considering hanging it from the wall, but wasn't sure about the weight of the hive so I'm leaning toward a roof mount platform. We are in upstate NY and the summers here aren't long, but they do get warm. I was planning to build a cone shape exiter like you have shown and have it exit close to the entrance of the hive. There has been a lot of discussions about whether the bees will produce their new queen or not. Will they or should I get a new queen or nuc and try to get her established? This hive could be set up almost right next to where their entering the home.
So, with a past hive that had died, I was planning to try setting this up there and see what happens. The homeowner isn't in any hurry, he just would like the bees out of the home to prevent a further mess. I'm new to trapping them out and relatively new to bee keeping, but figured free bees are better than the cost!
The other friend is more interested in getting them out because their at the front top portion of the house up in the peak of the rake of the eave. I was wondering what your suggestion was for this one if I can put another roof mount hive on top that they would find and head into? I expect it would be about 3-4' from the opening and just around the corner. How long can the exit tube be? Can it be bent around the corner to redirect them to the new hive on the roof?
