Smoking Bees
Within
and outside the hive, bees communicate extensively by
smell. Nectar, pollen, diseases, other insects, brood,
the queen, drones - everything in the hive has an odor.
As complicated as the bees’ odor communication system
appears to be, the manner that beekeepers have developed
to overcome the bees’ ability to perceive odors - both
inside and outside the hive - is to puff cool, white
smoke in and around the hive. For reasons not clearly
understood, smoke stimulates bees to move to honey
stores and engorge on honey. This can clearly be seen
after applying smoke to a colony.
Early
smokers were little more than a smoldering fire beneath
or near a hive. Later, tobacco pipes were modified to
direct smoke into hives as were other early devices.
After evolving through many different designs and
styles, beekeepers in North America have a small, but
adequate range of smoker designs from which to choose.
The years of numerous smoker designs being commercially
manufactured seems to have passed.
Smoker
fuels are as numerous as are the beekeepers who use
them. However, common fuels are: grass clippings, pine
straw, sumac pods, cloth rags, rotted wood, wood
shavings, and burlap. Essentially, anything can be used
that produces cool, white billowing smoke and has not
been treated with pesticides or with fire retardants.
Under
normal conditions, smoke is effective for about 2-4
minutes before needing to be reapplied. Only use enough
to turn the bees back into the colony and direct smoke
into the hive. Attempting to smoke bees outside the
colony is generally an ineffective way to get them to
move where you want them.
Working
a Swarm
Swarms
are, without a doubt, both a blessing and a curse. The
blessing part is that a swarm can be harvested and put
to work in an apiary.
The
first thing to do with a swarm is collect it. At times
easy, sometimes impossible. Swarms high in the air can
be collected with vacuum devices, long ladders, or
heroic gymnastics. Most can be collected into bags,
boxes, supers or whatever and transported to permanent
housing; ensure that there is enough ventilation,
however, putting a strong swarm into an air-tight
container is a recipe for disaster! Swarms are
generally the gentlest of bees, but if left exposed for
several days, they can become hungry and much more
defensive. Always have a lighted smoker ready when
working swarms.
Once
collected and transported, a beekeeper can do many
things with this bunch of bees. The deciding factor is
often the size of a swarm. Large swarms, 4 or 5 lbs. Can
easily run themselves. Smaller swarms, 1-3 lbs. Can be
combined with other swarms for a large colony; or added
to a large colony to boost its nectar and pollen
gathering capability during a major flow.
To be
safe, all swarms should be considered infested with both
tracheal and Varroa mites and treated
accordingly. And, the queen heading that swarm is from
essentially unknown heritage. To be certain of the
future of that new colony, requeening as soon as
possible should be considered.
Gathering a swarm can be the most exciting activity a
beginner or seasoned veteran can experience. No two
calls are ever alike, and no two swarms are the same.
Removing Bees From Supers in Order to Extract Honey
Probably the oldest and most direct technique to remove
honey from bees was to bundle up as much as possible -
probably at night - and just tear into the colony, in
the process taking numerous stings. The development of
smokers to subdue bees was a major advancement in honey
removal. Using a lot of smoke, however, is not
recommended as it can easily permeate the wax combs and
contaminate the honey.
Aside
from taking excessive numbers of stings, removing honey
during cold weather periods is a simple way to take
honey from bees. Practically all the bees will be in the
cluster and not in the supers. Though bees don't care
for the procedure, they can be brushed from combs with a
soft bristle brush. This procedure is simple and cheap,
but can result is a substantial number of bee stings.
The old standard still applies. Take the honey when the
fewest bees are at home.
Bee Traffic-Flow Control Devices to Remove Honey
Various
types of bee valves (eg. the Porter Bee Escape) and
escape boards are available that will allow bees to move
from: supers but not return to them. The Porter bee
escape fits in the inner cover (Bee Escape + Inner Cover
= Escape Board). This model of escape board and others
that work on the same principle, is put beneath honey
supers. Cool nights are a great help in the successful
use of escape boards because bees move back to the brood
nest area leaving the supers. Advantages are: (1) bee
escapes and escape boards are inexpensive, and (2) they
are simple. Disadvantages are: (1) without cool nights,
bees may be slow to move down, (2) robber bees may enter
cracks and take honey, (3) supers are handled twice
(once to put on the escape devices and a second time to
remove them), and (4) a second trip to the yard may be
required.
Blowing and Chemicals to Remove Honey
High
volume-low pressure air devices can be used (eg a shop
vacuum, leaf blower) or can be purchased commercially to
remove bees from supers. They are fast but often
expensive. However, easily obtained leaf blowers are
changing that. The downside of these devices is that
they do put a lot of bees in the air, and cause
considerable confusion in the bee yard during harvest.
Bee yards located near high human populations can get
out of control. Chemicals can also purchased and used
by soaking false covers that have a cloth interior.
These so-called "fume pads" remove bees quickly, but the
downside is the strong odor that permeates everywhere
when they are in use.
