Can a building be tented to kill bees and what should be used?

If your building has honey bees; never kill them. They have stored honey and and the honey will melt free of the comb and draw ants wasps and other vermin. Call a bee keep and a carpenter to open the walls and remove all bees, dead bees, and wax comb. The carpenter can restore the wall and block access holes.

If you building has yellow jackets, whiteface hornets, carpenter bees, what to use?

Use a licensed exterminator.This is no job for the beginner.
