Carpenter Bees are solitary bees, meaning they do not live in a colony. The large Carpenter Bees appear blue or black in color, and with a metallic sheen. Carpenter Bees often are found burrowing into the exposed dry wood of buildings and structures. Although they don’t colonize, Carpenter Bees can be seen in close proximity with each other, and will even share the same burrow since the burrows are large enough to accommodate several.

Carpenter Bee Control

Carpenter bees prefer to attack wood, which lacks any type of treatment, stain or paint. Treat problem areas to avoid future issue, and further discourage nesting by closing garage doors and other access points. Paint is historically better to use than stains and treatments, as they prove to be a more effective defense and deterrent against Carpenter Bee infestations. If you begin to hear noises in the walls of your home, quickly plan for treatment, as the bees may gain entry to the interior. The carpenter bee is a metallic blue black color and measures a substantial ¾-1 inch long. They have orange or yellow hair and can look like bumblebees, except for their tail section. The carpenter bee has a black tail section with no hair. Spring is the right time for Carpenter Bees, so keep an eye out on your property and see when the little buggers start creating issues in your home, eaves and siding.

We have tons of calls every spring season about Carpenter Bees, and know that we have the right carpenter bee control products and advice to make you successful with your carpenter bee problems. Using our established protocol and product recommendations, we know you will be successful with controlling and eliminating any carpenter bee problem you may have.

Treat burrows from bees with liquid insecticides. Products like Tempo SC and Demand SC are both great choices, as they are very effective. Retreatment may be necessary, depending on the circumstances and the resistance of the bees, as well as the correct application of the insecticide.

Tunnels from Carpenter Bees, which have already been excavated, are best treated by puffing an insecticidal dust, such as Tempo SC or Delta Dust, in the nest opening. Aerosol sprays labelled for wasp or bee control are also effective. To apply insecticide correctly, leave the hole open for a few days after treatment to allow the bees to contact and distribute the insecticide throughout the nest galleries. Plug the opening later with caulks, wood putty, wooden dole rounds, etc.

Application of a good insecticide in the early springtime to the area that was under attack in the previous year, will significantly reduce large amounts of damage. Plan ahead with ePestSolutions’ range of carpenter bee control products!

There is nothing more annoying that sitting outside to have a drink of coffee and have sawdust drop in your cup. Female Carpenter Bees love to return every year to the same location to lay her brood and watch her baby grow. It sounds like a lovely story, but not when it is tearing up your siding and eaves.

Carpenter Bees can do a fair amount of damage every year to your home, and having little holes all over the siding and eaves, is one thing that’s not only not very attractive, but also gives entry to other insects. Therefore, they are something that needs to be taken care of and not just ignored.

If you are trying to figure out if you have Carpenter bees or just a bumble bee, just think about this: Carpenter Bees somewhat resemble bumble bees, but they will have a different type of nest. For the most part, they are solitary, and it will only be the female and the male carpenter bee that you will see in the area. You may have a ton of them digging holes, but they are not sharing them for the most part. Carpenter bees can be found around wooden fences, patios, doors, eaves, wood shingles, window frames, and log cabins. When the female establishes a nest, she will bore into the wood at a right angle. Saw dust created from the characteristic clean out with an opening approximately ½ inch wide.

Exterior surfaces that are coated with paint or varnish can be potential barriers to the bees, as it will be more work for them to chew through extra surfaces. But of course, long term they are not 100% effective and will break down over time and you will find yourself with carpenter bees thinking the eaves and siding will be an exciting home for their family.

Staying on top of your carpenter bee problem is really what needs to happen. If every year you have the same problem, then applying a good residual insecticide on those surfaces will reduce the populations. Only after you have applied a high quality moisture resistant dust into the holes to kill the Carpenter Bee and her young, then you can close up the hole.

Determine the Best Way to Eliminate the Pests:

There are a variety of DIY pest control solutions that may be appropriate, but the best solution is the way that is most appropriate for personal concerns. For example, if the goal is to encourage the pests to make their home in a different location, then it may not be necessary to kill the bees. Instead, finishing the wood and using woods that are not appealing to the pests can simplify the situation. You can apply a wood preservative, such as Boracare that preserves the wood and contains a borate, but this has to be done before the wood is stained or painted. Boracare will also prevent all wood destroying insects and some fungus from damaging the wood. It is something that we personally use at our home and office on everything that goes up. It is worth the little investment for a very long term solution.

When the infestation has become a significant problem, it may be necessary to kill the Carpenter Bee, so that it’s possible to seal up the holes and prevent further infestations in the future. You will want to check out our Carpenter Bee Kits that have the main ingredients necessary for doing it the right way and keeping you and your family safe. All the products in the kits can be reused. Cyzmic CS Insecticide is a great general pest control product and works great for perimeter barrier mosquito control. You will also want to make sure you have a duster, bellow duster or Centro bulb duster to help youpuff small fine layers of dust into the openings. They do come with extensions, so that they will make easy work of the dust application and you will not necessarily have to get too close.

Select the Most Appropriate Products:

After determining that the only solution is extermination, wait until the appropriate time before taking any measures. Carpenter bees return to the nest during the evening hours and stay inside the nest for the night. Wait until the activity has stopped before using an appropriate pest control product. They can sting, but usually will not search you out as a bumble bee would when on the attack. A Carpenter Bee will swarm and dive bomb you when they feel threatened, so keep your wits about you.

The appropriate carpenter bee control products can depend on the severity of the infestation. In some cases, an insecticide spray from ePestSolutions can be a quick way to eliminate the bees when they are in the nest. Otherwise, pesticides that are applied to the nest or the wood can also help.

There are a variety of products and solutions that can help eliminate carpenter bees, but it’s important to evaluate the options before taking any measures. If the goal is to exterminate the problem, then an insecticide is the way to attract this problem. The dust application is necessary to get into the opening, as you do not want to apply a wet insecticide inside these holes and make an added mess. Environmentally friendly options can be a good choice, if there are concerns about the health of small children or pets. We carry a large selection of green carpenter bee control options, if you are interested in not using an actual chemical.
