Elimination And Control
- To control carpenter bees, do not concentrate on the adults. The annoying male
bees are easy to kill with a wasp freeze such as PT515. However, killing the male will do
nothing to stop the cycle. You must treat the nest with a product which will have a long
residual killing time. If you spray liquid residuals in their hole, you may kill the
female bee. The eggs are protected, however, and six to twelve months later the larva will
emerge. Since liquids are absorbed by porous wood, they will be gone when the larva hatch.
This means the larva have a strong chance of survival.
- To insure complete control, use a dust called Drione.
It has a desiccant action and can remain active up to 3 months in the nest and the nest
galleries. When the larva emerge they will be dehydrated by the Drione Dust. Apply the Drione
to the nest openings and deep inside the cavities drilled by the carpenter bees.
This will kill any emerging carpenter bees and larva in the future. Since the holes
can penetrate several feet, you should use an applicator like the Crusader
This tool will help you to apply the dust with enough force to reach deep in the nest
where the eggs and larva will be living.
- You should also treat any wood surface that you wish to protect with
Cyper WP, Suspend SC,
D-Fense SC (same as Suspend SC), Tempo WP or
with Cyper WP. These products (D-Fense
SC, Tempo and Cyper WP) are used extensively by pest control
operators throughout the United States for most of their monthly, quarterly or once-a-year
pest control accounts. These products are active against many pests including
Choose the product that best suits your overall needs for pest
control in and around your home or business. Tempo
and Cyper WP are wettable powders (powder
concentrates that are mixed with water for spraying) which are
odorless and give at least 90 day residual action indoors.
Mix Cyper WP or Tempo
at the rate of 2 scoops per gallon when controlling carpenter bee infestations; spray on
any wood surface you wish to protect from carpenter bees or where they may want to bore
holes and create galleries. One gallon can treat up to 1000 sq./ft. This
application rate works well when treating cedar homes and log cabins. These structures are
particularly subject to carpenter bees.
- If you tend to have recurring carpenter bee problems every Spring or Fall, may
have to do more spraying. This will deter future infestations of many pests,
including carpenter bees. Apply D-Fense
SC, Tempo WP or Cyper WP once every 4 weeks in the spring when they are most active. Once a month
outdoor applications throughout the summer will probably provide protection but do not
forget your fall application. Although rain and humidity will break down the
chemical, it is active enough so that even trace amounts will help chase carpenter bees,
wasps and hornets away.
- Use a pump sprayer to do the treatment. Start treating high on the siding
under the eaves. Since the product will run down the side of the home, you will get the
best coverage this way. The most economical way to spray is with a garden pump
sprayer. Our sprayer is capable of reaching up to 30 feet high. Product comes out
slowly and it may take a couple of gallons to treat your home. However, the pump
sprayer avoids excessive waste.
- If you have a lot a area to treat and are not concerned about wasting some
product, use a Dial-A-Mix hose end sprayer with a liquid concentrate Cypermethrin (Demon EC, Cynoff EC or
Cypermethrin EC 4 ounce.) This hose-end type
of sprayer is used by filling it with the Cypermethrin product, hooking it to your garden
hose and then depressing the trigger. This releases the water from your hose which
in turn siphons out the required amount of Cypermethrin to provide the correct
solution. This type of application is much easier to use than a pump sprayer.
Many times the water pressure is able to spray higher than the pump sprayer which could
prove important if trying to reach high places on your home. Expect a small amount
of waste when using the hose end sprayer. On a special note, do not use a
"Miracle Gro" or other "no-clog" hose end sprayer which lets water mix
with the concentrate. These sprayers are designed for water soluble fertilizer and
will not work for this application.
- When Spring has sprung, insects will rebound from a long and cold winter.
The carpenter bee is one such pest. Treat their nests directly with Drione to insure long term control. Use D-Fense
SC, Cyper WP or Tempo WP on decks, overhangs and fence posts in the
Spring to stop further nests from starting. A little prevention will go a long way
in reducing the amount of unsightly damage caused by carpenter bees.
- Applying Bora-Care
wood preservative is best for prevention of powderpost
beetles, old house borers,
termites and even helps with carpenter
ants, but will do little for carpenter
