Carpenter Bee Treatment

Carpenter bees are hard to hate, they are very cute, and they are an important part of any ecosystem because of their cross-pollination activities. They are also docile and rarely sting unless when pushed to the wall. 

But then, one day, you go out to your yard and look up and you see holes all over your ceiling and roof and you are there wondering what could have done that. You investigate and then you find out that the cute bees you have just been admiring are the culprits. Then your eyes clear up and you start thinking of the most effective way to get rid of them. 

That is the sad but true story of the carpenter bee. Useful and pretty, but ultimately unwanted because of what they have to do to be useful. They do less damage to wooden structures in your home than, say carpenter ants and termites, but the little they do adds up and could still cause major issues. So, how do you detect an infestation by these gentle insects? 


Appearance – There are two basic species of carpenter bees in North America: large and small. The larger bees are the more troublesome specie, causing damage for property owners, they are slightly less than an inch in size. They are often confused with bumblebees due to their size and hairy upper bodies. The carpenter bee has a black, shiny abdomen with black and yellow or black and orange markings. The bumblebee on the other hand has a hairy and yellow abdomen. 

Behavior- Carpenter bees chew through wood, hollowing it out wood to form their new homes, most times in the wood siding of your home. It is not rare for carpenter bees to use tunnels that have been in use before rather than creating new ones. Often damage is noticed above the first level of your house in the form of perfectly shaped holes in the siding. Carpenter bees do not like eating wood, they will leave wood bits and dust behind as a show of their getting cozy in your walls where they will seek shelter and have their young. Male carpenter bees are not known to sting but they can aggressively “dive bomb” perceived threats to the nest. So watch out for those perfect circular holes in any part of your house, especially on the exterior, you can detect an infestation that way. 

Flying bees- If you happen to spy many large bees buzzing around the eaves of your house, it is likely you have a carpenter bee problem. You should get on top of that right away. 


Carpenter bees seek out dry, weathered, and unpainted wood to live in. The wood of house siding, door trim, and windowsills are good homes, as well as many other worn or unpainted wooden surfaces. 

 Carpenter bees have lofty aspirations, so if you live near or own a home that has multiple stories, they will most likely burrow on the second floor – to keep themselves safe. 


Wondering why you need to get rid of your carpenter bee infestation urgently? Here are some reasons below: 

       The activities of carpenter bees tend to be a nuisance and a threat to your residence. When too many carpenter bees burrow at once into the side of your home, it can cause costly structural and aesthetic damage to it. 

       Sometimes Woodpeckers will often peck at your house siding looking for carpenter bee larvae for food. This can cause further aesthetic damage to the façade of your house. 

       Male carpenter bees don’t sting, but they can be territorial. Female carpenter bees, on the other hand, can sting if provoked which can be a danger to your family and pets, if you have any. 

       Carpenter bee feces can also stain the façade of your house. 

       It is important note know that carpenter bee females usually come back to the same nest every year and keep expanding their tunnel network to accommodate more eggs. If this happens, the aesthetic and structural damage to your structure can progressively get worse if it is not treated.

Here are some simple steps that you can take to ensure that you do not have a recurrence/second wave of the infestation:  

       If you plan on replacing wood facia boards after dealing with a carpenter bee infestation, it is important that you don’t stop at replacing it. Ensure you cover all sides with aluminum or vinyl. This is so that the carpenter bees cannot chew through again (they can’t get through aluminum or vinyl). 

       Try to paint all the unfinished wood or furniture outside your building. Painted wood is less attractive to carpenter bees. 

       Seal any exterior opening cracks, crevices, and holes that you can find with caulk. This denies the bees access to your house. 

       To prevent the female carpenter bees from coming back to the nest again, you would need to block the openings to their nests with caulk. Make sure you do this only when you are sure there are no bees left in the nest. If you trap any bee in there, they will just chew through the blockage.
