How to Get Rid of Carpenter Bees With WD-40: A Comprehensive Guide

Carpenter bees are a type of solitary bee that are notorious for their habit of tunneling into wooden structures. While they do play a role in pollination, their burrowing can cause significant damage to homes and other wooden structures over time. Fortunately, there are many solutions for eliminating carpenter bee infestations. One of the most effective and versatile solutions is WD-40.

The Benefits of Using WD-40 to Eliminate Carpenter Bees: A Comprehensive Guide

WD-40 is a multi-purpose spray that has been used in households for over 60 years. It is known for its ability to lubricate, protect against rust, and remove grime. However, it also has a wide range of benefits for eliminating carpenter bees. Here are a few reasons why using WD-40 is an effective solution:

It suffocates carpenter bees

WD-40 is a petroleum-based product that essentially suffocates the carpenter bees. When sprayed directly onto their nests, it can kill them instantly and prevent them from further burrowing into the wood. Moreover, it can penetrate deep into the tunnels created by the bees, killing them without having to remove the wood.

It serves as a preventative measure

WD-40’s oily consistency helps to repel and discourage carpenter bees from burrowing into wood in the first place. When sprayed onto wooden surfaces, it creates a barrier that makes it difficult for the bees to grip on and penetrate the wood. This is particularly useful for areas that are difficult to reach or are prone to infestations. Regular application of WD-40 can prevent a carpenter bee problem before it even starts.

It’s versatile

WD-40 is not just ideal for getting rid of carpenter bees, but it also serves well for several other purposes. It can lubricate sticky hinges, mechanical equipment, and machines. It can also be used to clean and protect metal surfaces from rusting or corroding.

Say Goodbye to Carpenter Bees with These Simple Steps Using WD-40

Here are some easy steps for using WD-40 to eliminate carpenter bees:

Step 1: Wear protective clothing and gear

Carpenter bees can be aggressive when they feel threatened. So, it’s essential to wear long pants, long-sleeved shirts, a hat, and gloves. You should also wear a protective mask to prevent inhaling WD-40 fumes.

Step 2: Locate the bee nests or entry points

Carpenter bees burrow through wooden surfaces and create their nests inside. If you see the large holes, which are about the size of a dime or quarter, on the outside of your home or wooden structures, then those are likely to be the entry points. Check the perimeter of your house, decks, sheds, any wooden outdoor furniture, and other wooden objects to look for the entry points.

Step 3: Spray WD-40 directly into the entry points or nests

Shake the can of WD-40 thoroughly before using it. Then, spray it directly into the entry point or nest of the carpenter bees. Be sure to spray it directly into the hole as deeply as possible to reach all areas where the bees are present.

Step 4: Seal the entry hole

Once you have sprayed WD-40 into the nests, close the entry holes with wooden dowels or caulking. This should be done immediately after spraying to prevent any bees from escaping. The sealant will also prevent other pests from using the same hole to access your home.

Step 5: Continue prevention with regular application of WD-40

Carpenter bees are persistent, and they will often attempt to burrow into the same wooden structures repeatedly over time. To prevent such infestations, spray WD-40 regularly over wooden surfaces. This will serve as a deterrent, making it difficult for the bees to burrow into the wood.

WD-40: The All-In-One Solution to Carpenter Bee Infestations

Using WD-40 not only eliminates carpenter bee infestations, but it also serves as a preventative measure for future infestations. Additionally, it’s often more cost-effective than hiring a professional exterminator and safer for the environment than traditional pesticides.

Top 3 DIY Methods for Using WD-40 to Eliminate Carpenter Bees

Here are three ways to use WD-40 to eliminate carpenter bees from your home:

Method 1: Direct injection

This method involves locating the entry point or nests of the carpenter bees and spraying WD-40 directly into them. It’s the most effective method, but it requires precise aiming and positioning of the nozzle.

Method 2: Spraying the exterior surfaces of wooden structures

This method involves spraying WD-40 all over the wooden surfaces of your home or structures. It’s less effective than direct injection, but it can serve as a preventative measure against future infestations.

Method 3: Use a DIY trap

This method involves creating a DIY trap using WD-40, a plastic bottle, duct tape, and a wooden dowel. Cut a plastic bottle in half, turn the top section upside down, and attach it to the lower section with duct tape. Then pierce a hole with the wooden dowel into the plastic and spray WD-40 inside. The fragrance of the WD-40 will attract carpenter bees, who will then become trapped in the device.

Step-by-Step Guide on How WD-40 Can Help You Get Rid of Carpenter Bees

Here is a more detailed guide on how to apply WD-40:

Step 1: Prepare

Wear protective clothing, goggles, gloves, and a mask to avoid inhaling fumes. Move any flammable objects out of the area.

Step 2: Locate entry points and nests

Walk around your home and yard to identify where the carpenter bees are nesting. Look for round, half-inch holes in the wood, which signify the location of their nest. Gently tap on the wood to hear where the bees are lairing.

Step 3: Spray WD-40 into the entry points or nests

Shake the can of WD-40 well before use and hold it upright. Spray the WD-40 into the entry point or nest, ensuring that it reaches as far as possible. The WD-40 will drench the tunnels with its oil, suffocating the carpenter bees and their larvae.

Step 4: Seal the entry points

After spraying the WD-40, plug the holes with wooden dowels or caulking. Seal each hole with enough material to prevent the entrance of any lurking bees or other pests.

Step 5: Repeat the process

After seven days, check if there is any bee activity. If you find any, repeat the above steps

Why WD-40 is the Best Solution for Carpenter Bee Removal and Prevention

WD-40 is the most effective solution for tackling carpenter bee infestations. It not only removes carpenter bees, but it also serves as a preventative measure against future infestations. Using WD-40 is also more cost-effective and safer for the environment than traditional pesticides. Additionally, WD-40 is versatile, making it an excellent household item for a range of other uses.


Carpenter bees can be frustrating to deal with, but with the help of WD-40, they can be eliminated quickly and safely. Regular application of WD-40 can also serve as a preventative measure. However, it’s essential to take all appropriate safety measures when using WD-40 and to seal entry points carefully.
