Can also go over the box & frames with a propane torch to loosen any gooped up wax/cocoons. As wally mentioned, a healthy colony of bees will tend to matters just fine. You'd be absolutely amazed by some of the places they pick to colonize, deadouts that are writhing with shb larvae, wax moth, slime, etc... Seeing is believing & I've watched them move into set ups I would never imagine placing them in!
