Carpenter Bees

Carpenter Bee Biology

Carpenter bees get their name from drilling through wood and nesting in the hole.  This bee creates a near-perfect 1/2 inch diameter hole.

  • The female carpenter bee will bore a channel 6 inches or longer.
    Bees' eggs are laid in these chambers, packed with and seperated by pollen gathered by the carpenter bee.
  • The male spends most of his time flying around the nest playing guard.     Only the female can sting.  Simply killing the male will not solve your problem.

Signs of Carpenter Bee Infestations

Half-inch, round holes appear, and piles of sawdust are found underneath.  Along with the coarse sawdust found underneath the entrance, there are usually dirty-yellow streaks of fecal matter staining the wood below the hole.  If you are near a nest, you will likely be buzzed by the male carpenter bee on guard.  He is loud and aggressive, but has no stinger.  The female can sting but she is normally very docile.   A single pair (male and female) occupies each nest.  It is not uncommon to find several pair of carpenter bees nesting in one structure.  They frequently nest near each other and often in the same area year after year, causing extensive damage.   You may find old holes near newer ones.  Sometimes the female will renovate an old nest gallery and reuse it.

Control of Carpenter Bees, Carpenter Bee Elimination

**   Skip down to carpenter bee elimination products.  **

To control carpenter bees, do not concentrate on the adults.
You should treat the nest with a product which will have a long residual killing time; this kills adults and their young, as the young hatch.  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 for several months in the nest galleries. When the larva emerge they will be killed by the Drione Dust.
Apply the Drione  with a Crusader Duster 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.
You should also treat any wood surface that you wish to protect with D-Fense SC, Tempo WP or with Cyper WP.   Wettable powders  (Tempo WP 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.
D-Fense SC is a very economical, odorless insecticide with many uses in and around the home.
These products are active against many pests including carpenter bees.
If your home has cedar siding or is a log home:
Wettable powder formulations will leave a visible residue on dark surfaces which is undesirable for some people.  Cedar and log homes may also be bombarded with carpenter bees which requires special attention.  Most of our customers who have these types of homes prefer to use D-Fense SCDemon EC or Cynoff EC for their carpenter bee elimination.
Carpenter Bee Kit #3
This Carpenter Bee Kit contains the necessary products for those who have heavy infestations (of carpenter bees) on cedar or log homes. Each kit contains 1 pint Demon EC, 1 pound Drione Dust, a Crusader Duster and a Dial-A-Mix hose end sprayer.
These products are also much cheaper to use when treating larger areas or where high volumes of insecticide spray is required.  When treating these larger areas (on log or cedar homes) use a hose-end sprayer for application.  This allows you to treat exterior walls with greater ease and reach higher areas without having to use a step ladder.  For severe infestations of carpenter bees on cedar and log, you will need to spray twice (2 weeks apart) the first month.  After your spray has been allowed to dry, apply your Drione Dust to all possible carpenter bee holes or entry points.  Repeat spray and dust as necessary.
Choose the product that best suits your overall needs for pest control in and around your home or business.  Tempo WP and Cyper WP are all wettable powders (powder concentrates that are mixed with water for spraying for various insect pests) which are odorless and give at least 90 day residual action indoors.  Cynoff EC and Demon EC are liquid concentrates which give about 30 days residual and no visible residue.  Mix 1/2 to 1 ounce of these liquid concentrates per gallon of water.   Mix  Cyper WP or Tempo WP 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 your wettable powder insecticides once every 4 weeks in the spring when they are most active. Once a month 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.

The most economical way to spray is with a garden pump sprayer. Our Chapin 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.
If you have a lot a area to treat and are not concerned about wasting some product, use a hose end sprayer with a liquid concentrate (D-Fense SC, Demon EC, Cynoff EC, etc.) 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.
