Carpenter Bee 101
Where do carpenter bees live?
Carpenter bees live throughout the United States, though the western species of carpenter bees prefer to nest in oak, eucalyptus, and redwood. Eastern species will target pino, redwood, fir, and cedar.
Do carpenter bees sting yous?
Many people find themselves intimidated by these pests considering of their sheer size and resemblance to bumble bees. (Bumble bees have thick yellow hair on the belly while the tail end of a carpenter bee is black and shiny.) Surprisingly, though, carpenter bees are not structurally or physically threatening (male carpenter bees take no stingers and females are usually docile).
"Carpenter bee stings are rare," explains Dr. Jim Tew, an entomologist who specializes in beekeeping with Ohio State University. "The males are territorial and will hover around you, only they are bluffing."
What exercise carpenter bees practice?
Female carpenter bees could teach carpentry classes with their precision and reuse of material. First work each April and May, females apply their strong jaws to drill holes into the surface of the wood. In one case the entrance is consummate, the females make a sharp xc-degree plow and begin tunneling. These tunnels volition continue anywhere from 1 foot to four feet until the females stop to carve out a nest.
Carpenter bee nests are really a series of small cells with walls made of chewed forest pulp in betwixt. A female often creates six to 10 cells in a row along the main tunnel. At the end of this excavated gallery of cells she volition get out a mixture of regurgitated nectar and pollen to feed her larvae. With her work complete, the female will dice. The food ball is plenty to proceed the larvae fed through the growth cycle, around seven weeks.
Sometime in August, the new adult carpenter bees will venture from the nest, only to render for hibernation through winter. The following spring the new generation of carpenter bees begin the life cycle again. The females will recycle the old nests, with some modifications, for their own larvae, sometimes for years at a fourth dimension. Fresh sawdust along with drips of pollen and waste make tunnel entrances easy to spot.
Too, expect to hear drilling sounds within the forest equally the females work on their nests and tunnels. Ironically, the males are given the chore of guarding the nests although they take no stingers.

Carpenter Bee Prevention
Co-ordinate to Tew, there is no universally accepted, good style to control carpenter bees, there are, however, many prevention methods. Owners of log homes must be extra-vigilant from the beginning.
Coat the forest early
"It is best to coat the forest earlier the bees 'find' it because the next generation will return the post-obit year to try again, and again, in one case the wood has been tunneled," says Barbara Bloetscher, too an entomologist with Ohio State Academy.
While woods stains will not deter carpenter bees, any exterior finishes with oil or polyurethane bases will help. Each bound, start early on, and plan on spraying the exterior of your log home with an insecticide.
Look for the right ingredients
If yous decide to practise the spraying yourself, look for insecticides with a pyrethroid as the active ingredient. This chemical is also known as bifenthrin, cyfluthrin, deltamethrin, and permethrin. Many pesticides tin be purchased on the Internet in full-bodied form.
Virtually exterminators, for example, use a production known as Demand CS equally a deterrent to carpenter bees. Demand CS is a microencapsulated pyrethroid containing the active ingredient lambda-cyhalothrin. Demand CS tin be purchased in concentrated form with each 8 oz. canteen making forty gallons of solution. The price for ane bottle runs effectually $60.
Some pesticides, like Demand CS, may require special licensing training or registration of the user in certain states. Brand certain with your local extension bureau, EPA office, or state list of registered pesticides earlier making whatsoever purchases. Some states will provide licenses and/or permits for personal use of registered pesticides for a nominal fee.

How to Go Rid of Carpenter Bees
What do you do if these bees have already turned your dwelling into their home? Starting time, have precaution. As mentioned earlier, female person carpenter bees do have stingers and, although usually docile, could attack if provoked. Wait until it is dark out to treat the damanged wood, every bit the bees are less active then. Futhermore, be sure to wear some protective clothing.
Next, choose your strategy. Because the nests are vital to the bees year-circular, destroying them gives yous the best adventure at extermination. There are a variety of options when it comes to extermination. Here are some pros and cons of different strategies:
Should y'all kill carpenter bees?
Choosing an insecticide for carpenter bees
In the past, Borax was used as a common insecticide for carpenter bees. The disadvantage with this method, even so, is length of time it takes to kill the bees. Borax, pumped into the archway holes, works slowly, giving the bees fourth dimension to cause more harm.
"Borax is toxic to birds, bees and other wildlife," cautions Bloetcher. "Although people refer to it every bit a 'home remedy,' when used improperly and immune to blow and bladder in the air, it can exist lethal to other vertebrates and invertebrates."
For existing tunnels, insecticidal dust, similar Sevin Dust, has been constitute to exist the most effective. Again, look for a pyrethroid as the active ingredient and pump pulverization into the opening. Droplets sprays can too be used in entrance holes. Wait a few days to allow the bees themselves to distribute the poison.
Will wasp spray kill carpenter bees?
Be careful what you purchase, though, pesticides with stomach poisons are useless confronting carpenter bees considering the bees don't actually swallow the wood. In addition, pesticides can degrade in a matter of weeks or months making a reapplication necessary during the summer if carpenter bees are spotted. For spot treatment, annihilation labeled effective against bees and wasps will also deter carpenter bees.
Endmost the archway
Afterwards using the insecticide, plug the hole with a wood dowel coated in carpenter'due south glue, caulking, or putty.
"Simply caulking burrow entrances closed will not stop the problem," explains Tew. "Carpenter bees tin cutting through caulking compounds."
Tew suggests using 0000 steel wool (4-0) dipped or sprayed with insecticide to close the archway. This will cause the bee to chew on the steel wool for a while earlier escaping. The steel wool hole volition need to be caulked over to foreclose rusting every bit the wood degrades. Again, whatsoever contact with the burrow entrances should be done at night or early evening to assure the bees are inside and will not assault.

How to Become Rid of Carpenter Bees Naturally
For those disinclined to the apply of pesticides, in that location are some mutual-sense approaches to carpenter bee infestation. Some homeowners have found that waiting until winter to plug archway holes with wood dowels to be most effective. Considering the bees hibernate in the nests, they become trapped in bound when it's fourth dimension to emerge.
Strangely, these bees are less inclined to diameter out of forest than they are into it. Others swear by the use of roofing nails, set in the entrance holes and covered with a caulking compound, this must be done in the autumn after the new adults have left the nest, otherwise the bees will bore their way out. Taking a wire and inserting it far into the tunnels to destroy the nests is some other alternative, although this requires the right timing and protective clothing to prevent stings.
"Carpenter bees are very discerning about the lumber they assail," says Tew. "If just a unmarried trim lath is being attacked, replacing that board might solve the problem." Finally, in that location is the option of doing nothing. "The command path of least resistance," continues Tew, "is simply don't attempt to control them. After the first few killing frosts, the bees will dice. Patch the burrow entrances and hope the next flavour volition produce fewer pest bees."
