When an owner wants bees gone, is there something you could squirt into the wall to drive them out and make them leave their brood behind. I doubt it but I ask. An owner has bees in his wall, they were in the lower floor garage ceiling space but tried a cutout from the garage and the main hive is actually in the wall, even though they enter the floor space first. They obviously built up in the wall then moved into the floor with lots of fresh comb. He wants them gone but has health problems/concerns and doesn't want chemicals sprayed into the wall. I suggested a pyrethrin or similar if he can live with that and spray a bit in each day and knock them over.
He thought of finding the top of the hive in the wall and drilling a few small holes and squirt something in to drive them out. I thought they will just move to the next wall cavity etc.
Is there something that will drive them out without killing them, will they leave their brood? I expect the Beego/beequick/honey robber products will just drive them down, but not make them ALL pack their bags.
