Hive is in the steel cannister with the plants on top. Bees entering through small holes, large hole is a solid pipe running to the bottom, bees are in cavity around it. Cannisters are cemented in what appearrs to be a retaining wall. The competition recommended cutting open with an acetylene torch. My thought is that would cook or fumigate the bees. This is a paid job, any ideas? I do have a cutoff saw with steel cutting blades. Do welders have a less dangerous/flamey way to cut steel than a torch? Maybe a Hogan trapout? See both pics.
