northwest tennessee | Go to YouTube and put in carpenter bees and a trap will come up. You could make one yourself and is simple. I bet it will work too. I have been fighting these things for years. |

Lapel, In | Spraqy some Malathion into the holes. Then plug the holes with caulking. They are bad this year aren't they. |

West Tennessee | From my personal experience, if you mix the malathion strong enough it will kill most of them, the ones not dead won't be back. I usually mix it about 4-5% active ingredient. Just got rid of some here at home last week. |

Ohio | I have seen alot of them here in Ohio too.
Integrated Pest Management
When dealing with carpenter bees, it is preferable to locate tunnel entrances during the daytime, but treat after dark on a cool evening when carpenter bees are less active. Wear protective clothing to avoid any stings during treatment.
Prevention
Keep all exposed wood surfaces well painted with a -polyurethane or oil-base paint to deter attack by carpenter bees. Periodically inspect painted surfaces, because the coatings will begin to deteriorate due to weathering, leaving exposed wood that the bees then can easily attack. Wood stains will not prevent damage. Consider using aluminum, asbestos, asphalt, vinyl siding, and similar non-wood materials that are not damaged by carpenter bees. Seal existing gallery entrance holes to discourage carpenter bees that are looking for potential nesting sites.
Mechanical Measures
A non-insecticidal management approach is to deny carpenter bees access to their galleries by sealing each entrance hole. Thoroughly plug the hole with caulking compound, wood putty, or a wooden dowel affixed with wood glue. If possible, also fill the entire gallery system with a sealant. Carpenter bee galleries are a critical resource, since the bees spend much of their time inside a gallery, and they require its protective conditions to survive the winter. Bees that are trapped inside a caulked gallery typically will not chew out due to behavioral constraints. This barrier approach has promise for reducing future carpenter bee infestations.
In new nests, the single female often can be swatted and killed, or she can be captured and crushed or otherwise destroyed. Larvae and pupae can be killed by inserting a sturdy wire into the entrance hole and probing into the gallery as deeply as possible.
Insecticides
A chemical treatment using an appropriately labeled insecticide can protect wood for short periods, especially in the spring and summer when carpenter bee nesting activity is apparent. Dust formulations typically provide residual effects and are effective due to the nature of carpenter bee gallery construction. Precisely inject the dust directly into each nest entrance hole and as deep into the tunnel as possible and also apply it to the adjacent wood surface. Wait for a few days before plugging entrance holes since adult bees should be allowed to pass freely to distribute the insecticide within the galleries. Newly emerged bees also will contact the dust when attempting to leave their gallery.
For use as a preventive, an insecticide should be applied to wood in early spring before carpenter bees begin excavating nests. The insecticide kills the bees that contact it on the wood?s surface. However, a preventive approach has limitations because of the difficulty in applying a chemical to all exposed wood on the house where bees could nest. Furthermore, such insecticides usually degrade in a matter of weeks or months so repeated applications are needed to maintain a lethal dose of the insecticide. Some pest management companies report good results against carpenter bees by spraying wood with a microencapsulated pyrethroid, Demand? CS insecticide (registered for use only by licensed professional applicators), which contains the active ingredient lambda-cyhalothrin. A number of other pyrethroids (bifenthrin, cyfluthrin, deltamethrin, permethrin, etc.) also are labeled for use against carpenter bees.
Insecticides that act as stomach poisons, such as borates, typically are ineffective against carpenter bees, which do not ingest the wood that they excavate.

| I got one with a brass grill brush today. Worked good. Might have added some flavor to the burgers. |

Near-north Ontario, French River | Many years ago my older bro would load up some 12 gauge shells with wheat, and a light powder load . Wouldn't dare shoot towards a window but gave reasonable range ( 20-25 feet) , the wheat was "soft ' enough that it didnt damage anything but the bee's LOL Usually just waited near where the bees were doing their handwork , smoked em when they got close enough. |
