INTRODUCTION
Honey bees
get their common name from the sweet yellowish to brownish fluid
they make from the nectar of flowers and use as food. Honey
bees not only provide honey and wax, but as pollinators are
of far greater importance. They are also responsible for a large
share of insect stings, although many stings blamed on “bees”
are actually done by yellowjackets.
Honey bees are worldwide in distribution.
RECOGINTION
Adult worker’s body length about ½-5/8” (11-15 mm). Color usually orangish brown to sometimes black with body mostly covered with branched, pale hairs, most dense on thorax. Eyes hairy. First segment
of hind tarsus enlarged, flattened. In addition, hind lack
apical spurs; front wing venation with marginal cell narrow,
parallel-sided, and 3rd submarginal cell oblique; hind wings with jugal lobe (lobe on rear margin near body). Barbed stinger present.
Queens
slightly larger, about 5/8-3/4” (15-20 mm) long, pointed abdomen
extends well beyond wing tips, with smooth stinger. Males
or drones robust, about 5/8” (15-17 mm) long, stinger absent.
Africanized
honey bees look just like our “domestic” bees. A specialist
is required to identify individual specimens.
SIMILAR GROUPS
(1) Yellowjackets (vespidae)
have abdomen usually banded with yellow and black, hind tarsal
1st segment not enlarged, hind wing lacks a jugal lobe (lobe on rear margin near body). (2) Other bees
(various families) lack hairy eyes, have apical spurs on hind
tibiae, lack having front wing’s marginal cell narrow and parallel-sided
and 3rd submarginal cell oblique. (3)Some syrphid flies (Diptera: Syrphidae)
which resemble honey bees, with 1 pair of wings.
BIOLOGY
Honey bees are social insects and live as colonies in hives, with mature
colonies of 20,000-80,000 individuals. Adults are represented
by workers which are infertile females, a queen or inseminated
female, and drones (males) which come from unfertilized eggs.
The
entire population overwinters. There is only one egg-laying queen in the hive
and she mates only once. She can lay as many as 1,500 to 2,000
eggs per day, and may live as long as 5 years. The queen produces
many pheromones, mostly from her mandibular glands, which regulate among other things the production of
new queens and inhibit development of worker ovaries. The young
workers care for the young or brood, build the comb, provide
hive ventilation, and guard the hive entrance. Older workers
serve as foragers to gather pollen, nectar, and propolis or bee glue. Workers live only about 5 to 7 weeks during the
summer but those emerging in the autumn, overwinter.
Drones (males) appear periodically and are short lived, usually
living only a few weeks.
Honey
bees swarm primarily when the colony size gets too large for
the available hive space or the queen begins to wane or fail.
New queens are produced and the old queen leaves with a large
number of workers.
HABITS
Honey bees
are not aggressive, and do not search for something to attack.
Instead, they are defensive and will attack only whatever seems to threaten the colony.
Swarms
first move to a temporary site such as a tree branch. The swarm
will usually remain here for about 24-48 hours until permanent
quarters are located, and then moves on. Permanent quarters
may consist of a bee hive, hollow tree, hollow wall, attic,
etc., typically some place which is sheltered from the weather.
Bees
in a swarm are very docile and not likely to sting because they
harbor no food stores or young and therefore, have nothing to
defend. Likewise, honey bees encountered away from the hive
are unlikely to sting unless severely provoked, like stepping
on them. However, if the hive entrance is approached, the guard
bees can become very aggressive. Worker bees have barbed stingers
and when used, the stinger, poison sac, and associated tissue
are torn from the body. If the stinger is not removed immediately,
muscle contractions will drive the stinger deeper and deeper
into the skin and there is greater time for toxin injection.
In addition, the stinger gives off a pheromone which attracts
other bees and induces an alarm and attack behavior. Therefore,
immediate removal with a fingernail or knife blade is recommended;
squeezing only forces more venom in.
The
normal reaction to bee stings is local pain for a few minutes
followed by swelling at the sting site which subsides in a few
hours. Often itching and heat may last for a few hours. First-aid
consists of quickly removing the stinger with a fingernail or
knife blade. After stinger removal, do not rub the area because
this causes the venom to spread, or scratch the area which may
cause secondary infection, but clean it with soap and water
followed by an antiseptic. A cold compress will reduce pain
and swelling. If the reaction is more severe than a small welt, consult a physician immediately
because death can occur within 15-30 minutes from severe allergic
reactions.
Africanized
honey bees are much more aggressive and will sting with little
provocation, even swarms may be dangerous. They will pursue
the intruder/victim for up to 328 ft (100 m) whereas, domestic bees pursue only about 33 ft (10 m). They
use a wider range of nesting sites, sometimes including subterranean
cavities.
CONTROL
For swarmers in the yard, contact the cooperative extension service or call
a local beekeeper supply shop for beekeepers interested in removing
swarms. These same contacts are worth a try for live removal
from walls and attics.
Live
removal of honey bees is desirable and the preferred method
in the case of brick walls, but it is often impossible to locate
anyone willing to do this. Live removal involves trapping the
bees out and capturing them with a decoy hive containing a queen
and a few bees, killing the queen and the few remaining bees
with pyrethrins or resmethrin, and after
several days allowing the bees back in to remove the honey.
Next, the nest void should be treated with a long-lasting repellent
dust to discourage wax moths, dermestid beetles, etc., and then immediately sealed. This whole process
may take 3-6 weeks.
If
honey bees must be killed in a wall or attic, pesticide application
should be made at night using only background light; a bee veil
should be worn. Appropriately labeled aerosol pyrethroids are most convenient and effective, with dusts
being second choice.
For
walls, first locate the entrance/exit(s) being used. Next, the
colony’s nest should be located because the nest can be far
enough away from the entrance that entryway-applied insecticides
will not reach the bees. The nest can best be located at night
by tapping on the walls in the area of buzzing and listening
for the loudest sound. Also, honey bees keep the center of their
nest at about 95°F (35° C) which will warm the wall enough such
that it can often be detected with one’s hand.
For
walls, first seal any possible entrances to living quarters
such as window sashes. Then the insecticide application can
be made either directly through the entrance hole or by drilling
a small hole (3/32-18” or 2-3 mm) through the inside wall, the
latter being necessary for nests located some distance from
the entrance hole. Seal the application hole immediately after
insecticide introduction. For attics, direct application is
required.
The
next day the dead bees, comb, and honey must be removed or else
as the wax deteriorates, there will be a strong honey and dead
bee odor, the honey will often seep through the plaster walls,
and/or this debris will attract other insects and mice. In the
case of a wall, the wall must be opened up. It is suggested
that the potential customer be notified in writing of their
responsibility in this matter before any contract is signed.
In
the residential situation, it may be desirable to discourage
foraging bees from coming around the home. This is especially
true if small children or allergic people are present. Discouragement
consists of the removal or preventing access to any sugar, food,
or water which may attract them, such as soda cans, flowers,
water dishes, etc. Recommend that flowering vegetation be located
away from doorways, decks, sidewalks, mailboxes, and other areas
frequented by people. Also, lawns should be kept free of white
clover and flowering weeds.
