My G'son asked for advice on removing a swarm in a friend's garage. They cut out a section of plywood on the outside. They have fairly well filled a space between studs about 3 to 4 tall and wide with numerous combs attached to the top plate and extending to the bottom. I haven't been there. this is from a picture. Is a vacuum used to collect bees a special low velocity type. Any suggestions on how to proceed?
