Beekeeping is a great hobby, whether you keep bees for pollination,
honey, profit, medicinal uses or all of the above. But getting started
with bees can be expensive if you use conventional hives. A basic setup
with bees can cost more than $200, and building conventional hives and
frames is time-consuming. But there’s a simpler, less-expensive and more
natural option: top-bar hives. The top-bar method of beekeeping allows
you to make simpler, inexpensive hives. Build them now and you can start
keeping bees next spring.
In the top-bar system, you build simple box hives with slats (bars)
of wood laid across the top, to which the bees attach their wax comb.
With growing concerns about colony collapse disorder and
the resulting decline in the number of pollinators, gardeners might
consider maintaining a top-bar hive of honeybees simply to increase
vegetable and fruit yields through better pollination.
Top-bar
beekeeping is for both urban and rural dwellers who want to keep bees on
a modest scale, producing honey and beeswax. Above all, top-bar
beekeeping is for people who love bees and understand and appreciate
their role in the pollination of many wild and cultivated plants.
If
your goal is to obtain the absolute maximum amount of honey regardless
of all other considerations, top-bar beekeeping is not for you. This
style of beekeeping can produce adequate amounts of honey, but the
emphasis is on sustainability and keeping healthy bees rather than
maximizing honey crops.
Natural vs. Industrial Beekeeping
Beekeeping
does not have to be complicated. And you need none of the stuff in
those glossy supply catalogs to keep healthy, happy and productive bees.
Nearly
all conventional beehives in use in the United States and Europe are
similar. They consist of rectangular wooden boxes containing removable
wooden frames holding preformed “foundation” for the bees to build wax
comb on, plus a floor and a roof. The queen bee lays eggs in this comb,
and the bees store some pollen (their protein source) and honey in the
comb. Other wooden boxes, called “supers,” with (usually) smaller
frames, are stacked on top to store most of the honey crop.
In
some ways, this box-and-frame hive is right for the job — at least from
the beekeeper’s point of view. It’s a simple matter to lift individual
frames out of the hive to see what the bees are doing and, if you have a
strong back, it’s relatively easy to remove the honey crop. The uniform
shape of the honeycomb in the frames makes it easier to extract the
honey with a centrifuge.
For the bees, however, this conventional
system has several disadvantages. Bees naturally build comb in deep,
catenary curves (the shape made by a chain or rope suspended by its
ends). But the use of preformed foundation inside rectangular frames
forces bees to build comb according to our requirements, not theirs. Bees prefer to adjust the size of cells according to their needs.
In a top-bar hive, the bees are encouraged to build their wax comb
(which holds the cells they fill with honey or developing bees) from a
thin strip of “starter wax” applied to the wooden bars, which simply
rest across the top of the box that forms the hive. To extract honey from this wax comb, you crush it in a strainer and allow the honey to drain into a jar.
Top-bar beekeeping requires only one of the simple, versatile hives
described below and a sharp knife. Instead of using a smoker to calm the
bees when you open the hive to inspect bees or harvest honey, you can
use a hand-held spray bottle containing water and, perhaps, a few drops
of a mixture of essential oils or cider vinegar.
Top-bar Hive Design
Top-bar
hives have been used for thousands of years and are still popular in
developing countries. I created a top-bar hive design with sloping sides
and side entrances. The hive boxes are 36 to 48 inches long. The hives
are 18 inches wide (outside measurement at the top) by 12 inches deep,
measured at the ends. The trapezoidal shape is close to the natural
shape of the comb. It’s strong and virtually eliminates attachment of
comb to the sides of the hive — a useful feature for the beekeeper. This
top-bar hive is simple to construct using inexpensive or recycled
materials — just be certain the wood hasn’t been treated with chemicals
that would harm the bees or you. For example, do not use green,
pressure-treated lumber or lumber that may have been sprayed with a
pesticide.
Bees build their wax combs from the bottoms of wooden
bars that are 17 inches long, 1 3/8 inches wide and about
three-quarter-inch thick. The bars rest on the upper edges of the sides
of the hives, giving an internal width of 15 inches. A central groove,
about one-eighth-inch deep, is cut along the length of each bar using a
circular saw and is filled with molten wax to provide a guide and anchor
point for the bees to build their comb. Alternatively, a strip of thin
wood can be fixed along the center of the bar and rubbed with wax. Two
inches on each end is left free of wax to discourage the bees from
building comb attached to the sides of the hive.
The floor can be
either solid or mesh, the latter being preferable in summer and hotter
climates in general. The mesh allows ventilation and prevents the
buildup of debris inside the hive. But it’s a good idea to have some
method of closing the bottom of the hive during winter if your bees will
be exposed to strong winds.
This long top-bar hive is strong,
versatile and easy to build, even for someone with only basic
woodworking skills. It’s also easy to manage. After the hive is in
place, the heaviest lifting you will need to do is to remove the roof.

ReplyDeleteGreat to know people are trying to support the bee populations. Warnings about the top bar hive, however. The top bar design orignates from research done in hot African conditions. If you live in the northern temperate regions, the challenge is overwintering the bees. The topbar only allows for about 20 pounds of honey, whereas a 2-3 box traditional method allows for at least 40-100 pounds. Bees need enough room to cluster over the winter to generate heat. I doubt the topbar hive could successfully overwinter in our cold climate.Also bees need enough food to get through the cold dark months. I seriously question the practicality of the top bar hive with one box for northern climates. The traditional Langstroth design is time-tested and allows for enough honey stores and space for natural organic beekeeping.

Great article. I would just like to make one quick point. If you live the eastern US DON'T use the water and vinegar mix to spray your bees with. The Small Hive Beetle is attracted to the cider vinegar and the first thing you know your hive will be infested with them. I learned this the hard way.
