How to Get Rid of Carpenter Bees

The sound of the flying carpenter bees next to your ear in the dead of the night is the most pestering sound you can ever hear. You may confuse them with bumblebees because carpenter bees have similar coloring and body anatomy. And though these benign creatures rarely sting (only the female can, when provoked), getting rid of them is crucial for ensuring a safe and pest free environment for everyone. This guide will share all the details you need to get rid of them.

Open house- Nesting season

According to Mike Potter, an entomologist at the Uuniversity of Kentucky, Carpenter bees are usually spotted between late spring and early summer. That’s when you know they’re searching for a new home to build their nest. If only they could be explained the house isn’t for sale!

Buzzing stingers

Surprisingly, the male carpenter bees guard their nest aggressively if any one comes in close proximity to it even though they have no stingers. On the other hand, the female carpenter bees are fierce: they have stingers and are not afraid to use their weapon to attack you. The sting of female bees is quite painful, and for those who might be allergic it can lead to hospitalization.

Damage and harm caused by Carpenter Bees

If the infestation is in a large group for several years, it causes wood decay, fecal deposits and fungi. The structure of the wood and household can be weakened due to internal burrowing of galleries and tunnels. If water enters the burrowed tunnels, it may lead to wood decay, and build-up of fungal deposits. Fecal deposits cause staining and attract birds that love to eat insects such as wood peckers. You will hear the scraping sounds and saw dust on wooden surfaces making the house feel inhospitable for guests.

Occupied Territory—Selection Of Wood For Burrowing

Carpenter bees build their nests by tunneling into wood and laying their eggs. Before they design their blueprint, they go wood shopping. Redwoods, Cedar, Cypress are few of their favorite. The more soft, bare, weathered and unpainted the collection is, the more valuable it becomes to the carpenter bee community. They are usually found on the eaves window trim, decks and outdoor furniture etc. When you start to hear sounds, observe coarse saw dust from the furniture and the color of fresh cut wood from within. You need to gear up for a war.

Eviction—Getting Rid of The Pests

Initially the following techniques could be used once the bees have started constructing their nest:

  1. Paint the all the exposed wood present inside and outside the household, especially the ones they like.

  2. Applying wood stains and preservatives may expel them to some degree.

  3. During the season when carpenter bees are looking for their nesting sites make sure the garages and outside buildings are kept closed.

Insecticides—Sting Operation

Keep insecticides at home will be useful. There are variety of such chemicals available which help eradicate the problem. They are as follows:

  1. Residual insecticide:  use aerosol sprays in areas where the carpenter bees are active. Few of the examples are: Demon WP, Fenva Star cap. What we highly recommend is Firponil Foaming Aerosol.  

  2. Residual Insecticide Dust:  you expose the abandoned tunnel with Insecticidal dust to ensure the tunnel will not be infested by the pests again. Such as Tempo Dust and D Fense Dust etc. many have curved tips that can reach the tunnel very easily.

  3. Carpenter bee kits: these products have longs lasting effects and many are eco friendly

  4. Carpenters glue: the evacuate hole must be plugged in using a Dowel coated with carpenters glue or wood putty. This decreases the chances of another infestation and wood decay.

  5. The Carpenter Bee Traps: they attract and trap the bees. If any sites are infested all you have to do is hang them nearby peaks and corners, preferably the sunniest side and extinguish the pests.

The carpenters—Extermination

Make sure while the entire treatment and extermination plan is being carried out, wearing protective clothing and implementing the mission at night time would be advisable. Furthermore, the insecticides being recommended may not be legal in all states, therefore do make sure to use the legalized insecticides.

Prevention is better than cure

Few of the cautionary methods which can be useful are as follows:

  1. Make sure cracks and crevices are sealed to stop the pest from crawling in.

  2. Woods should be painted and varnished so that they stay away from burrowing them.

  3. Keep insecticide and bee traps all set and prepared. We recommend applying an insecticide called Dominion 2L as a preventative treatment. Mix the insecticide and spray the wood to the point that they’re wet. As soon as the nesting season starts the bee trap itself will do most of the work before it can enter the house.

  4. Spray all the vulnerable areas before the carpenter bees take over. For example: the window sills, under decks and rail sidings. Insecticide will make sure the households are inhospitable for their nests.

Buzz for your thought

Instead of waiting around for Carpenter bees to infest your household you must make sure to take all cautionary measures to ensure bee infestation does not take place. It’s always better to do it yourself than to take extreme measures and spend a lot on calling in the professional.
