Re: Cut out from behind plaster walls
A hole saw will let you investigate the size of hive. A thermal scan would let you know where the brood is, but that is probably overkill.
A sawzall with a medium or fine blade will make less of a mess than circular. Finer blade = more work, less mess. Depending on the plaster and how it is coated dampening with water for several hours down your cut line can cut down on the dust. If you cannot wet it, cut between tape. Wall paper can hold plaster together pretty well sometimes, you might even slap some on before hand.The really old method had a second plaster wall inside the studs.
Cut down the side of the studs and add doublers to patch the hole. Use a sheetrock hand saw to make your cross cuts. Start small and see if you can remove comb through cut.
Close off the room and put a box fan in the nearest window before you start. If painted, it is lead based until proven otherwise.
Doing a trap out before the removal might make the job easier inside.
