Why Carpenter Bee Control is Needed

Why is carpenter bee control needed? This is a question that many people ask and understandably so. After all, carpenter bees are not nearly as aggressive and dangerous as wasps and hornets and they are less likely to sting you than honey bees. So, what exactly makes them a threat and why do they need to be eliminated? Let us take a look.

The Problem with Carpenter Bees

First of all, it is 100% true that carpenter bees generally do not pose a threat to human beings as in they do not attack and sting you at the slightest of provocations like wasps or hornets do. They do, however, pose an entirely different problem – structural damage.

Carpenter bees can cause a great deal of damage to wooden objects. They tend to drill holes and make their nests in wooden structures. It could be your doors, windowsills, decks, railings, roof eaves, or fences. Any wooden structure that is sufficiently easy to drill into becomes a potential nesting site for these bees and they will burrow themselves deep into the wood and lay eggs there.

There are two types of carpenter bees – large and small. The large ones are more common and they are also the ones that are likely to cause more damage. The holes they drill are generally ½ inch wide and the tunnel they excavate could be anywhere from 4 to 8 inches long. This is one of the reasons why a carpenter bee infestation, if kept unchecked for a long time, could hollow out and damage the wooden structures in your place.

Moreover, there is an aesthetic angle to the carpenter bee problem as well. Doors, windows, and roofs ridden with holes are not a pretty sight and they lessen the overall appeal of your property. This again is a reason why homeowners generally try to get rid of carpenter bees as quickly as possible.

How to Get Rid of Carpenter Bees?

Carpenter bee control generally involves a two-pronged approach – the application of insecticide and the sealing up of the holes.

Applying an insecticide dust into the drill holes is the first course of action. Once it is applied, the nesting site should not be disturbed for a couple of days, during which time the bees will come into contact with the insecticide and die. Once they are dead, the sealing up process can be done.

Sometimes, an aerosol spray might be required to get rid of the bees buzzing in and around the nesting site. The aerosol could also be sprayed into the holes if required. Once all the bees are dead – particularly the female ones, as they are the ones that are capable of stinging – the holes can be sealed up completely.

A weather resistant caulking compound is generally what is used to seal up the holes. Once everything is sealed up, the whole structure should be painted with exterior paint or varnish, since carpenter bees are less likely to damage treated wood.

If you are going to build a new wooden structure – be it a fence, deck, roof, or anything else, it is a good idea to do so with treated wood to minimize the risk of infestations.

Is DIY Bee Removal a Good Idea?

No, it is not a good idea, even if you are a DIY enthusiast. Carpenter bee control involves the application of insecticides, which require careful handling. Moreover, there are many types of insecticides available and only a pest control expert can decide which one to use, depending on a number of factors.

Secondly, and more importantly, though carpenter bees are not as dangerous as wasps, hornets, or even regular honey bees, they still are capable of stinging, particularly when they are provoked. So, there is a good chance you could get attacked by a bunch of bees when you try to spray the aerosol or apply the insecticide. This is one of the main reasons why you should leave it to the professionals.


Thirdly, any pest control treatment requires safety gear and proper equipment, both of which you are not likely to possess unless you do it for a living. Trying to remove or exterminate a beehive or colony without proper equipment and safety gear is very risky and is not recommended under any circumstances. So, it is always better to leave it in the hands of professionally trained carpenter bee control experts.
