How to Protect Wood from Carpenter Bees

Protecting Wood from Carpenter Bees

Carpenter bees can cause significant damage to wooden structures if left untreated. In order to protect your wood from these pests, it is important to take proactive measures. This article will provide you with step-by-step instructions on how to effectively protect your wood from carpenter bees.

Identify and Seal Entry Points

The first step in protecting your wood from carpenter bees is to identify and seal any existing entry points. Carpenter bees typically bore into wood to create their nests. Inspect your wooden structures carefully, looking for small holes or burrows. These entry points will often have a pile of sawdust or wood shavings nearby.

Once you have identified the entry points, use a sealant or putty to fill them. Make sure to choose a product that is specifically designed for outdoor use and is resistant to weather and moisture. Apply the sealant generously, ensuring that the entry points are completely covered. This will prevent carpenter bees from accessing the wood and creating new nests.

Apply a Protective Wood Finish

In addition to sealing entry points, applying a protective wood finish is essential in safeguarding your wood from carpenter bees. Choose a wood finish that contains insecticides or repellents specifically formulated for carpenter bees. These finishes are designed to deter bees from boring into the wood and discourage nesting.

Prior to applying the wood finish, make sure the surface of the wood is clean and free from dirt, dust, and debris. Use a mild detergent and water to wash the wood, and allow it to dry completely before proceeding. Once the wood is ready, follow the manufacturer’s instructions for applying the protective finish. Apply multiple coats if necessary, ensuring thorough coverage.

Regularly Inspect and Maintain

To ensure long-term protection against carpenter bees, it is important to regularly inspect and maintain your wooden structures. Conduct periodic inspections, especially during the spring and summer months when carpenter bee activity is at its highest. Look for signs of new entry points or bee activity, such as fresh sawdust or holes.

If you notice any damage or signs of infestation, take immediate action to address the issue. Reapply sealant to any new entry points and consider applying an additional coat of protective wood finish. Regular maintenance will help to prevent carpenter bees from causing extensive damage to your wood.


By following these steps, you can effectively protect your wood from the destructive nature of carpenter bees. Identifying and sealing entry points, applying a protective wood finish, and regularly inspecting and maintaining your wooden structures are key in preventing carpenter bee infestations. With proper care and attention, you can enjoy your wooden property without the worry of carpenter bee damage.

Frequently Asked Questions

Here are some commonly asked questions about how to protect wood from carpenter bees:

Question 1: What are carpenter bees and why do they damage wood?

Carpenter bees are large, solitary bees that burrow into wooden structures such as decks, eaves, and fences to create nests. The female carpenter bee excavates tunnels inside the wood, causing damage to its structure over time. Male carpenter bees, although they may appear aggressive, do not have stingers and are generally harmless.

To protect your wood from carpenter bees, it is important to take preventive measures and address any existing infestations promptly.

Question 2: How can I identify signs of carpenter bee infestation?

Signs of carpenter bee infestation include round or oval entrance holes, sawdust-like material (known as frass) beneath the holes, and buzzing sounds coming from the wood. You may also notice yellowish stains on the wood surface, which are caused by the bees’ excrement.

If you suspect carpenter bee activity, carefully inspect the wood and look for these signs. Early detection can help prevent further damage.

Question 3: What are some preventive measures to protect wood from carpenter bees?

To protect your wood from carpenter bees, you can take the following preventive measures:

1. Paint or varnish the wood: Carpenter bees are less likely to burrow into painted or varnished wood. Ensure all exposed surfaces are adequately coated.

2. Fill existing holes: If you find existing carpenter bee holes, fill them with wood putty or a suitable filler. Sand and paint over the filled holes for added protection.

3. Apply insecticides: Treat the wood with insecticides specifically designed to repel or kill carpenter bees. Follow the instructions carefully and consider seeking professional assistance for effective application.

Question 4: How can I deter carpenter bees from nesting in the wood?

There are several natural deterrents that can help discourage carpenter bees from nesting in the wood:

1. Hang a fake nest: Carpenter bees are territorial and tend to avoid areas already claimed by other bees. Hang a fake nest made of paper or cloth near the wood to deter them.

2. Use aromatic oils: Carpenter bees dislike strong scents, so spraying aromatic oils such as almond, citrus, or tea tree oil on the wood surface can deter them.

3. Install traps: Carpenter bee traps can be effective in capturing and removing these bees from your property. Place the traps near the infested wood for best results.

Question 5: Are there any natural remedies to repel carpenter bees?

Yes, there are some natural remedies that can help repel carpenter bees:

1. Citrus peels: Place citrus peels, such as orange or lemon peels, near the infested wood. The strong scent can deter carpenter bees.

2. Clove oil: Mix clove oil with water and spray it on the wood. Carpenter bees find the smell unpleasant and are less likely to nest in treated areas.

3. Boric acid: Create a mixture of boric acid and water, then apply it to the wood surface. This natural insecticide can repel carpenter bees.

It’s important to note that while natural remedies can be effective to some extent, severe infestations may require professional assistance and the use of stronger insecticides.
