Removal of Carpenter Bees: 5 Pro Woodcare Hacks You Must Try

Carpenter bees, with their penchant for drilling perfectly round holes in our wooden structures, can be a real pain. They don’t eat the wood like termites; they’re just creating cozy little nests. However, those nests can weaken the wood over time, leading to structural damage and costly repairs. So, before we get into the nitty-gritty of getting rid of them, let’s understand what we’re dealing with.

Understanding the Carpenter Bee

Carpenter bees (genus Xylocopa) are often mistaken for bumblebees, but there are key differences. The easiest way to tell them apart is by looking at their abdomens. Carpenter bees have shiny, black, hairless abdomens, while bumblebees have fuzzy, hairy ones.

• Key Characteristics:

  • Large size (around 1 inch long).
  • Shiny, black, hairless abdomen.
  • Solitary nesters (though they often nest near each other).
  • Males are territorial but lack stingers (they can be quite intimidating, though).
  • Females can sting, but they rarely do unless provoked.

• Damage They Cause: Carpenter bees create tunnels in wood to lay their eggs. They prefer unpainted or weathered wood, making decks, fences, siding, and other outdoor structures prime targets. While the individual tunnels aren’t usually a huge problem, repeated nesting over several years can weaken the wood, leading to structural issues.

• Why Prevention is Key: It’s much easier to prevent carpenter bees from nesting in the first place than it is to get rid of them once they’ve established themselves. That’s why these woodcare hacks focus on prevention and early intervention.

Hack #1: The Power of Paint and Sealants

One of the simplest and most effective ways to deter carpenter bees is to treat your wood. These bees prefer raw, untreated wood. Think of it like this: they’re less likely to build a house on a property that already has a “No Trespassing” sign (in this case, a coat of paint or sealant).

• Why it Works: Paint and sealants create a barrier that makes it more difficult for carpenter bees to drill into the wood. They also make the wood less attractive to them.

• How to Do It:

  1. Preparation: Start by cleaning the wood surface. Remove any dirt, debris, or old paint. If the wood is weathered, sand it down to create a smooth surface.
  2. Priming: Apply a coat of exterior-grade primer. This will help the paint or sealant adhere better and provide an extra layer of protection.
  3. Painting or Sealing: Choose a high-quality exterior paint or sealant. I recommend using an oil-based paint or sealant for the best protection. Apply two coats, allowing each coat to dry completely before applying the next.
  4. Focus Areas: Pay special attention to the ends of wooden boards, as these are common entry points for carpenter bees.

• Case Study: I once had a client whose deck was riddled with carpenter bee holes. After cleaning and prepping the wood, I applied two coats of a high-quality oil-based exterior paint. The following year, there were significantly fewer carpenter bees around the deck. The cost of the paint and my labor was far less than the cost of repairing the structural damage the bees were causing.

• Tool Specifications:

  • Sandpaper (80-grit and 120-grit)
  • Paintbrushes (2-inch and 4-inch)
  • Paint roller (optional, for large surfaces)
  • Paint tray
  • Drop cloths

• Material Specs:

  • Exterior-grade primer
  • Exterior oil-based paint or sealant

• Cost: The cost of materials for painting or sealing a deck can range from $50 to $200, depending on the size of the deck and the quality of the paint or sealant. Labor costs can vary depending on your location and the complexity of the job.

• Skill Level: Beginner

Hack #2: Wood Preservatives: The Heavy Artillery

For wood that’s already susceptible to carpenter bee damage, or for situations where painting isn’t desired (like on log cabins or rustic furniture), wood preservatives are your best friend. These preservatives penetrate the wood fibers, making them less attractive and more difficult to drill into.

• Why it Works: Wood preservatives contain chemicals that are toxic to insects, including carpenter bees. They also help to protect the wood from rot and decay, which can further deter carpenter bees.

• How to Do It:

  1. Choosing the Right Preservative: Look for a wood preservative that’s specifically labeled for use against carpenter bees or other wood-boring insects. Borate-based preservatives are a good option, as they’re relatively non-toxic to humans and pets.
  2. Application: Apply the wood preservative according to the manufacturer’s instructions. This usually involves brushing, spraying, or dipping the wood in the preservative.
  3. Penetration: Make sure the preservative penetrates the wood deeply. You may need to apply multiple coats or use a pressure sprayer to achieve adequate penetration.
  4. Safety: Always wear gloves, eye protection, and a respirator when working with wood preservatives. Work in a well-ventilated area.

• Personal Experience: I once used a borate-based wood preservative on a log cabin I was restoring. The cabin had been heavily infested with carpenter bees, and the wood was starting to show signs of rot. After applying the preservative, the carpenter bee activity decreased dramatically, and the wood became much more resistant to decay.

• Tool Specifications:

  • Paintbrushes (2-inch and 4-inch)
  • Sprayer (optional, for large surfaces)
  • Gloves
  • Eye protection
  • Respirator

• Material Specs:

  • Borate-based wood preservative

• Cost: The cost of wood preservatives can range from $20 to $50 per gallon, depending on the type and brand.

• Skill Level: Intermediate (due to the need to handle chemicals safely)

Hack #3: Plugging the Holes: Sealing the Deal

Okay, so the bees have already moved in. Don’t panic! We can still evict them. The key is to plug the holes, but not before making sure the bees are gone.

• Why it Works: Plugging the holes prevents the bees from returning to their nests and laying more eggs. It also helps to prevent water from entering the wood, which can lead to rot.

• How to Do It:

  1. Timing is Everything: The best time to plug the holes is in the late afternoon or early evening when the bees are less active. You can also wait until the fall or winter when the bees have died off.
  2. Eliminating the Bees: Before plugging the holes, make sure the bees are gone. You can use a vacuum cleaner to suck them out, or you can spray a small amount of insecticide into the holes. Always follow the manufacturer’s instructions and safety precautions when using insecticides. Alternatively, you can use a non-toxic method like diatomaceous earth. Puff a small amount into the hole, which will dehydrate the bees.
  3. Plugging the Holes: There are several ways to plug the holes. You can use wood putty, caulk, or even wooden dowels. Fill the holes completely and smooth the surface.
  4. Painting or Sealing: After plugging the holes, paint or seal the area to match the surrounding wood. This will help to protect the repair and make it less noticeable.

• Case Study: I once had a client who was adamant about not using any insecticides on their property. Instead, we used a combination of vacuuming and diatomaceous earth to eliminate the carpenter bees. We then plugged the holes with wooden dowels and painted the area to match the surrounding siding. The client was very happy with the results.

• Tool Specifications:

  • Vacuum cleaner with hose attachment
  • Caulk gun
  • Putty knife
  • Drill (optional, for inserting wooden dowels)

• Material Specs:

  • Wood putty or caulk
  • Wooden dowels (optional)
  • Paint or sealant

• Cost: The cost of plugging the holes can range from $10 to $50, depending on the number of holes and the materials used.

• Skill Level: Beginner

Hack #4: The Power of Sound: High-Frequency Warfare

This might sound a little out there, but some people swear by it. Carpenter bees are sensitive to vibrations and high-frequency sounds. Using these to your advantage can deter them from nesting.

• Why it Works: Carpenter bees use vibrations to communicate and navigate. Disrupting these vibrations can disorient them and make them less likely to nest in the area.

• How to Do It:

  1. Ultrasonic Devices: There are several ultrasonic devices on the market that are designed to repel insects, including carpenter bees. These devices emit high-frequency sounds that are inaudible to humans but can be irritating to bees.
  2. Music: Playing loud music, especially music with a lot of bass, can also deter carpenter bees.
  3. Strategic Placement: Place the ultrasonic devices or speakers near areas where carpenter bees are known to nest.

• My Experiment: I tried this method myself, using an ultrasonic pest repeller near my shed. While I can’t say for sure that it was the device that did the trick, I did notice a decrease in carpenter bee activity in that area after I started using it. It’s important to note that the effectiveness of this method can vary depending on the device and the environment.

• Tool Specifications:

  • Ultrasonic pest repeller
  • Speakers (optional)

• Material Specs:

  • None

• Cost: Ultrasonic pest repellers can range in price from $20 to $100, depending on the brand and features.

• Skill Level: Beginner

Hack #5: Natural Repellents: Essential Oils and Homemade Sprays

For those who prefer a more natural approach, there are several essential oils and homemade sprays that can deter carpenter bees. These repellents won’t kill the bees, but they can make your wood less attractive to them.

• Why it Works: Certain essential oils and other natural ingredients have strong scents that carpenter bees find unpleasant. These scents can mask the natural odors of the wood, making it less appealing to the bees.

• How to Do It:

  1. Essential Oils: Several essential oils are known to repel carpenter bees, including almond oil, citrus oil, peppermint oil, tea tree oil, and eucalyptus oil. Mix a few drops of the essential oil with water in a spray bottle and spray the mixture on the wood. Reapply regularly, especially after rain.
  2. Homemade Sprays: You can also make your own carpenter bee repellent spray using ingredients like vinegar, garlic, and cayenne pepper. Mix equal parts vinegar and water, add a few cloves of minced garlic and a teaspoon of cayenne pepper, and spray the mixture on the wood. Be careful not to get the spray in your eyes or on your skin.
  3. Strategic Placement: Focus on spraying areas where carpenter bees are known to nest.

• My Go-To Recipe: My favorite homemade repellent is a mixture of water, peppermint oil, and a little bit of dish soap. The peppermint oil repels the bees, and the dish soap helps the mixture stick to the wood. I spray this mixture on my deck every few weeks during the carpenter bee season.

• Tool Specifications:

  • Spray bottle

• Material Specs:

  • Essential oils (almond, citrus, peppermint, tea tree, eucalyptus)
  • Vinegar
  • Garlic
  • Cayenne pepper
  • Dish soap

• Cost: The cost of natural repellents can range from $5 to $20, depending on the ingredients you use.

Strategic Insights: Long-Term Woodcare for Carpenter Bee Prevention

Beyond these five hacks, a proactive approach to woodcare is crucial for long-term carpenter bee prevention. This involves understanding wood types, proper seasoning, and regular maintenance.

Wood Selection: Choosing the Right Material

The type of wood you use can influence its susceptibility to carpenter bee damage. Hardwoods are generally more resistant than softwoods, but all wood types can be affected.

• Hardwoods vs. Softwoods: Hardwoods, like oak, maple, and walnut, are denser and more difficult for carpenter bees to drill into. Softwoods, like pine, cedar, and fir, are easier to drill into but often treated with preservatives.
• Treated Wood: Pressure-treated wood is highly resistant to carpenter bees and other wood-boring insects. However, it’s important to use treated wood appropriately, as it can contain chemicals that are harmful to humans and the environment. Always follow the manufacturer’s instructions and safety precautions when working with treated wood.

Seasoning Wood: Reducing Moisture Content

Carpenter bees prefer wood with a higher moisture content. Seasoning wood, which involves drying it out, can make it less attractive to them.

• Green Wood vs. Seasoned Wood: Green wood is freshly cut wood that has a high moisture content. Seasoned wood has been dried to a lower moisture content, typically around 12-15%.
• Drying Methods: There are two main methods for seasoning wood: air drying and kiln drying. Air drying involves stacking the wood in a well-ventilated area and allowing it to dry naturally. Kiln drying involves placing the wood in a kiln, which is a heated chamber that accelerates the drying process.
• Moisture Content Targets: The ideal moisture content for wood used in outdoor structures is around 12-15%. You can use a moisture meter to measure the moisture content of the wood.

Regular Maintenance: Catching Problems Early

Regularly inspecting your wooden structures for signs of carpenter bee damage is essential. The earlier you catch a problem, the easier it will be to fix.

• Inspection Checklist:
  • Check for round holes (about 1/2 inch in diameter) in the wood.
  • Look for sawdust near the holes.
  • Listen for buzzing sounds coming from inside the wood.
  • Check for signs of structural damage, such as sagging or cracking.
• Repairing Damage: If you find any signs of carpenter bee damage, take action immediately. Plug the holes, repair any structural damage, and apply a wood preservative to prevent further infestation.

Implementation Guidance: Getting Started

Ready to take action? Here’s a step-by-step guide to implementing these woodcare hacks:

1. Assess the Situation: Determine the extent of the carpenter bee infestation. How many holes are there? Is there any structural damage?
2. Choose Your Weapons: Select the woodcare hacks that are most appropriate for your situation. If you have a severe infestation, you may need to use a combination of methods.
3. Gather Your Tools and Materials: Make sure you have all the necessary tools and materials before you start.
4. Follow the Instructions: Carefully follow the instructions for each woodcare hack.
