Bob,,,you will thank yourself for taking the time to make a bee-vac. I'm not sure how I got along not having one! There are a few different plans out there for the vacs. Barry Birkey has a set on his site that looks pretty good. 'Ol Johnson sells one. The one I made is an adaptation of a couple different ideas. If your in the habit of capturing swarms and or hives,,,,just drop what your doing and get started on your own vac. You'll be glad you did. Gathering a hive, especially out of a wall,,is messy,,,no way around it. A vac is a huge help. Each year, I seem to get two or three swarm calls from schools. If you go in with the traditional "jerk the branch and the bees fall in the box" trick,,,you get a big cloud of bees that seem to freak out the little kiddies even more. Vaccuum them and it's no muss,,,no fuss. You'll love it,,,they'll love it
Now get to work
