How To Get Rid Of Carpenter Bees With WD-40?

Carpenter bees can be a nuisance for many homeowners, as they often create holes in wooden structures and can cause significant damage over time. Fortunately, there are many methods for getting rid of these insects, and one of the most effective is using WD-40.

What Are Carpenter Bees?

Carpenter bees are large, black and yellow bees that are often mistaken for bumblebees. Unlike bumblebees, however, carpenter bees do not live in colonies and are solitary insects. They are named after their tendency to build their nests in wood, often creating holes in wooden structures such as decks, siding, and fences.

The Damage Caused By Carpenter Bees

Carpenter bees can cause significant damage to wooden structures if left unchecked. They create large holes in the wood to lay their eggs, and the larvae feed on the wood, weakening the structure over time. In addition to the structural damage, carpenter bees can also leave behind a sticky resin that can attract other insects and lead to further damage.

How WD-40 Can Help?

WD-40 is a versatile product that can be used for a variety of purposes, including getting rid of carpenter bees. The oil in WD-40 can help to suffocate the insects, killing them quickly and effectively. In addition, the lubricating properties of WD-40 can help to plug up the holes created by the carpenter bees, preventing future infestations.

Using WD-40 To Get Rid Of Carpenter Bees

To use WD-40 to get rid of carpenter bees, simply spray the product directly into the holes created by the insects. Make sure to get the WD-40 into all crevices of the hole to ensure that the bees are suffocated. After spraying, plug up the holes with a piece of wood or other material to prevent future infestations.

Tips For Effective Use

To get the most effective results from using WD-40 to get rid of carpenter bees, it is important to follow a few tips. First, make sure to spray the product in the early morning or late evening when the bees are less active. This will give the WD-40 time to work before the bees can fly away.

Second, be sure to wear protective clothing, such as gloves and a long-sleeved shirt, when applying WD-40 to prevent bee stings. Finally, always follow the manufacturer’s instructions when using WD-40 and take all necessary safety precautions.


Getting rid of carpenter bees can be a challenge, but using WD-40 can be an effective solution. By suffocating the insects and plugging up their holes, WD-40 can help to prevent further damage to your wooden structures and keep your home free from carpenter bee infestations. Remember to follow the tips for effective use to ensure the best results.
