Black carpenter bees are one of the largest species of bees and are often found in the Greater Houston area. They’re typically black in color, but some possess yellow markings on their head like the bumble bee.
But, what exactly is a black carpenter bee? The carpenter bee earned its name from its nesting behavior— tunneling into hard plant material like bamboo or dead wood. Carpenter bees are from the genus Xylocopa bee species of the Xylocopinae subfamily.
In this article, you’ll know more about the activities of carpenter bees, their characteristics, as well as the various ways to get rid of them. On top of that, we’ll also include the scents they hate and many more!
Are Carpenter Bees Black?
Carpenter bee species are usually all black, but some possess yellow markings on their head like the bumble bees.
Their lower abdomen has little to no hair, appearing shiny black, the reason they’re sometimes called black bees. Females are all black, while male bees have yellow faces and white dots on their heads.
Furthermore, they have an almost identical look to bumble bees. The only difference is that carpenter bees are almost totally black.
They also have a shiny, bare abdomen rather than a fuzzy one. Like bumble bees, the carpenter bees aid in pollinating plants, especially flowers and vegetables.
What Do Black Carpenter Bees Do?
Adult carpenter bees drill tunnels in unpainted, dry, and weathered wooden objects like windowsills, doors, roof eaves, siding, beams, and more. You can treat, stain, or paint these things to prevent carpenter bees from destroying your wood items.
The strong scent of paint or stain repels black carpenter bees and stops them from damaging your wooden properties.
Are Black Carpenter Bees Bad?
Although carpenter bees don’t usually cause harm to you and your family, they can pose a threat to your house.
Like termites, carpenter bees excavate into the wood, making tunnels that can weaken many vital structures in your home.
Moreover, females can sting but only when they’re bothered. Males also seem aggressive as they fly around pets and people, but they aren’t harmful since they don’t have a stinger.
Where Do Black Carpenter Bees Live?
Black carpenter bees commonly live on untreated nesting sites, such as rafters, eaves, decks, wooden shake roofs, fascia boards, and outdoor furniture like wooden chairs and tables.
Do Black Carpenter Bees Make Honey?
Carpenter bees have over 730 species and none of them can make honey. This is because they belong to the subfamily Xylocopinae, which are not honey-producing species but are essential pollinators of crops, flowers, and plants.
How Big Does the Black Carpenter Bee Get?
The body length of an adult carpenter bee is approximately 1/2 of an inch to 1 inch or equal to 12.5mm to 25 mm.
Do Big Black Carpenter Bees Sting?
Only the female carpenter bees sting since the males don’t possess stingers. However, this is very rare and will happen only when you’re holding them or putting your fingers into their burrows.
How to Get Rid of Black Carpenter Bees?
To get rid of black carpenter bees effectively, you can use some of the given methods below:
One of the effective methods for controlling carpenter bees is using traps. To make the trap, get a wooden box and drill at least 1/2 of an inch on each side of it.
Then, insert the plastic bottle’s opening in the hole of the box bottom, and suspend it from the box. After that, hang the traps at each corner of your house, barn, or porch.
Once the bees enter the holes, they’ll fall into the plastic bottle, get trapped, and die eventually.
Paint Wooden Items
Another method you can try to get rid of carpenter bees is by applying paint on your bare wood.
This will repel carpenter bees from nesting or destroying your wooden structures or items and save you from possible damages.
Furthermore, applying a permanent finish on your stripped wood can be a practical preventive solution. Carpenter bees don’t like to drill in painted wood as they can’t feel or see the grain of wood if it’s painted.
Replace Wood Materials
Another way to repel carpenter bees is by replacing wood with aluminum, vinyl, or other non-wooden materials. Carpenter bees don’t like any items if it isn’t made of wood.
According to the University of Maryland Extension, spraying hornet, wasp, or bee aerosol formulations into the drilled holes of carpenter bees is useful. To apply, lightly spray the interior of the tunnel’s entrance.
That way, the returning bee will disperse the compound of the insecticide spray into the tunnel passageway and die in the process. When using insecticides, make sure to follow the label directions to ensure your safety and get the best results.
Call a Pest Control Professional
If none of the above methods work, call a pest control professional and let their team of pest experts handle your carpenter bees issues. This way, you can ensure that your pest issues will be solved professionally and in a timely manner.
