Yeah, keep us posted. I am going to check out a house today that sounds similar, it would be nice to have an option other than just walking away. I did a house last year where the entrance was about 7 feet up, and that was bad enough. A tip - I made up some hives out of rigid foam board, where the bottom was attached permanently, so only the lid came off. Didn't bother with an inner cover, the board is stiff enough that I could cut the grove for the frames to drop onto. Made carrying up and down the ladder a lot easier, although still heavy coming down with all the bees. Just duct taped the lid on. Doesn't last forever, but don't need that for a trap out. Here's a picture of the wooden box I had set up for the first try -
Lets just say that getting it back down the ladder full of bees didn't go well. So don't do that!
