Bee Hive Boxes & Frames

This year we are blessed to have seven active bee hives on our micro farm. We expanded till we had used all of our existing hive bodies and supers. So, we ordered some more un-assembled hive parts, and will post about putting them together.

We get our bee supplies from Mann Lake (http://www.mannlakeltd.com/), and they have a referral program that pays a small percentage. If you place an order, enter my "BeeBucks" number: 208208. Thanks!


Hive Bodies and Supers

The Langstroth hive dimensions were established in 1852, and I like this stackable system of hive growth and enlargement. There are two outside dimensions: one that will hold 10 frames (the most common) measuring: 16 1/4" by 19 7/8". The other option is the 8 frame body measuring 14" by 19 7/8". I started with the 10 frame size, and the parts are not interchangeable. I would go with the 10 frame size if I were starting out, as I have been able to pick up used equipment on occasion, and all the options I have ever come across are 10 frame.

We have two options for the height of the boxes, with the "deep" being the standard for the brood chambers, and deeps or the smaller "super" being for the honey collection. The only advantage of a smaller height is that the box full of honey would weigh less as you move it around for processing. For several years we only used deeps for all our boxes (brood and honey), but deeps full of honey are heavy! So this year we are trying some smaller honey supers as well.

The deep hive bodies:
  • 9 5/8" tall hive bodies
  • 9 1/8" frames
  • 8 1/2" foundation
The deep bodies and super boxes are assembled with glue and galvanized 7d nails.

The honey supers:
  • 6 5/8" supers
  • 6 1/4" frames
  • 5 5/8 foundation
The frames are assembled with glue at all joints. 1 1/4" nails are used to attach top bars and bottom bars to end bars. 3/4" nails are used to attach bottom bars to end bars or under the frame ear going from the end bar into the top bar.

Hive bases, screen boards, queen excluders, inner cover, outer covers are purchased assembled.


Bee Vacuum

We have made a bee vacuum, which has proved invaluable for swarm capture and hive removal. I will show you how we made ours, and offer to make one for you assembled if you would like. We will build and sell our assembled bee vacuum for $125, shipping included to USA street addresses. (Post a comment on this blog with your email address, and we will contact you for more details and payment info.) If you have the time and materials, it is not hard to make your own.

Our Bee Vacuum is composed of a top box with a connection hole for a standard shop vac to provide the suction. In the center of the unit, you place a standard hive body with frames to contain and occupy the bees drawn into the chamber. Then at the bottom there is a slanted board deep at the front where there is a hole for the bee suction hose, and shallow at the back to encourage the bees to draw up to into the frames. We use pool hose for our bee suction tube, it is smooth inside the hose to ease trauma to the bees in suction. The customer would supply their own hive body and shop vac.

Now let's look at the top and bottom unit in more detail. The top box is 4" in height, and has the outside dimensions of a standard 10 frame hive body (16 1/4" by 19 7/8"). The standard shop vac suction hose has a 3" diameter, and we cut a 3" hole into the back side of the unit. The lower surface, we install a fiberglass screen to keep any curious bees from being drawn out into the shop vac. The upper surface, we permanently install a Plexiglas cover. This allows you to monitor the bee density and activity from the outside, looking down through the screen into the hive body which is collecting the bees. Also into this top unit we install a suction relief valve in case the shop vac is producing more suction than you want. Opening this relief valve will bypass some of the suction.

The lower unit is the same outside dimensions, and 4" in height. This allows us to drill a 2" hole into the front face of this unit that will accept the pool hose. If any of the hose connections are not air tight, we use a round of masking tape which will seal up the mating surfaces. Pool hose can be obtained in 30' lengths, and we cut ours in two for a short suction hose, and the other being a longer suction hose. into the floor of the lower unit, we placed an inclined inner floor, sloping from the intake hole being its greatest height to very shallow at the back end of the unit. This slope gives the bees a convenient way to walk up the ramp and into the hive body and frames. The inner mating surfaces of the units have a weather strip as a gasket to help preserve the suction. The entire unit is held tightly together with a ratchet strap.

We have completed several trials of our bee vacuum with excellent results. After sucking up an entire feral hive, we found only a few dead bees in the lower unit. The bees remained happy and healthy to this day. Installing the bees into the bee yard is an easy process, as you do not have to transfer bees to a new box. We simply remove the vacuum top unit, and then move the bee filled hive body into its final position in the bee yard. The bees are already "home" when you vacuumed them into the hive body. We also really like being able to look into the vacuum and see how things are progressing during the removal, a feature we have not seen in any other bee vacuum out there.

We found it important not to suction bees that are coated with honey. In one occasion, we found this developed into a clump of bees in the middle of the suction hose. The pool hose we currently use is not clear plastic, so other than suction decreasing it was not immediately easy to tell what was happening. With care to not suck in honey covered bees, we have not had this problem again. When finished removing bees, we remove the suction tube from the bottom unit, and close it off so bees do not escape.Then you can turn off and remove the shop vac hose from the top unit. Keep all three units (top, hive body, bottom unit) all tightly strapped together until you are ready to install the bees in your bee yard.

Candles and Soap

This year our family farm has experimented with bees wax candles and soap making. Our soaps contain honey and bees wax. We may consider selling home made bars of soap and candles, dependent on demand. We will make a separate post on these activities in the future.


Hive Activities for August

August is the perfect month to treat your hives for Varroa mites. There are several treatments that can be applied during the honey flow, and by treating your hives now, they will have several generations of strong bees going into winter. Strong bees as winter comes on means a more likely hive survival. I suggest formic acid and hopguard.
