I'm a frugal man (My lovely wife calls me cheap). But I did make a Bee vac out of some used 2x4s and plywood, a clear plastic tub from Wally World and a piece of tube form Lowes or (maybe it Home Depo). For the vacuum I use my shop vac.
It’s real similar to ones found on the internet.

The only changes I made were, I used a large clear plastic tote to catch the bees in. I cut a 12†x 12†square in the lid (thou not very square I’m not much of a carpenter) Covered the hole with bee screen (1/4 inch mesh). Then I made a 14â€x 14†square box out of 2x4’s with a piece of plywood nailed to one side, to make it like a box. I set that open side down over the hole, on the lid and drilled a hole in one of the 2x4’s the same size as my vacuum cleaner hose. Stuck the hose in the hole for suction.
That makes a cheap the box to hold the bees and a vacuum source that most of us already have.
Then cut a 1 1/2†hole (or what ever size hard suction hose you are going to use) I splurged and bought a nice section of white 1 ½†hard suction, it was the most expensive part. Anyway dill the hole in one of the ends near the top, you just don’t want the bees to hit the opposite wall when they get sucked. Poke that nice. Expensive, plastic hose it the hole and you can start sucking up bees.
I did reinforce the 1 ½†hole in the tote with a small piece of plywood. I sandwiched two pieces together, one on the inside, one the outside and drilled right through both.
I also cut a 3x3 square out of the side of a milk jug to cover the hole when I’m done sucking and want to keep the bees inside.
I wanted clear suction hose but what I found was to soft and would collapse when under a vacuum. It would be real nice to be able to watch the bees fly down the tube.
You do not want too much vacuum or it will damage the bee’s wings. So if it’s too strong break the seal around the 2x4 and the lid. Mine is not a very good seal (I told you I’m not a carpenter) I have to lay a towel around the 2x4’s to get a good seal.
Hope this helps
