How To Get Rid Of Boring Bees Naturally (Woodworker’s Pest Fix)

Let’s bust a myth right off the bat: you don’t have to resign yourself to sharing your woodworking projects with those pesky boring bees. Many think that once those little buzzers move in, it’s game over. But trust me, it’s not! I’ve been knee-deep in sawdust and splinters for years, and I’ve learned a thing or two about keeping these unwanted guests at bay. And believe me, I’ve seen it all, from simple preventative measures to full-blown infestations that looked like a carpenter bee convention!

Now, you might be asking, “Why should I care about carpenter bees?” Well, beyond the obvious annoyance, their relentless drilling can seriously compromise the structural integrity of your wooden structures. And as a woodworker, I know how much pride we take in our creations. We want them to last! So, let’s dive into the world of carpenter bee control, naturally. I’ll share my hard-earned wisdom, tips, and tricks to help you reclaim your wood shop and keep those buzzing bullies away.

Understanding the Carpenter Bee Menace: Why They Target Your Wood

Before we go on the offensive, let’s understand our enemy. Carpenter bees, unlike honeybees, are solitary creatures. The females are the ones responsible for drilling those perfectly round holes (about ½ inch in diameter) into wood, creating galleries for their nests. These galleries are where they lay their eggs and store pollen for their larvae.

Now, why your wood? Well, carpenter bees prefer softwoods like cedar, pine, redwood, and fir. These are relatively easy to excavate. They also tend to target unpainted or unstained wood, especially if it’s weathered. Think of it as a blank canvas for their architectural endeavors.

Current Statistics and Context:

According to the National Pest Management Association (NPMA), carpenter bee infestations are on the rise, particularly in regions with warmer climates. Damage from carpenter bees can cost homeowners and woodworkers thousands of dollars in repairs annually. A study by the University of Kentucky found that untreated softwood structures are 80% more likely to be infested by carpenter bees within five years. That’s a sobering statistic, isn’t it?

Key Concepts:

Softwood vs. Hardwood: Softwoods come from coniferous trees (evergreens), while hardwoods come from deciduous trees (trees that lose their leaves annually). Softwoods are generally easier to work with but are also more susceptible to pests like carpenter bees.
Green Wood vs. Seasoned Wood: Green wood is freshly cut wood with a high moisture content. Seasoned wood has been dried to a lower moisture content, making it more stable and less attractive to pests. I’ve personally found that carpenter bees are less likely to target well-seasoned wood.

Prevention is Key: Fortifying Your Woodworking Fortress

The best defense is a good offense, right? Here’s my arsenal of preventative measures that have worked wonders over the years:

1. Surface Treatments: Painting, Staining, and Sealing

This is your first line of defense. Carpenter bees are less likely to drill into painted, stained, or sealed wood. Why? Because these treatments create a barrier that makes it harder for them to excavate.

Painting: Apply two coats of high-quality exterior paint. Oil-based paints are generally more durable and offer better protection than latex paints.
Staining: Use a penetrating stain that seals the wood pores. Look for stains with added UV protection to prevent weathering. I prefer oil-based stains for their longevity.
Sealing: Apply a clear wood sealant to unpainted or unstained wood. This will create a protective layer that repels water and deters carpenter bees.

Data Point: A study by Purdue University found that painting wood surfaces reduced carpenter bee infestations by up to 70%.

2. Wood Selection: Choosing the Right Materials

While carpenter bees prefer softwoods, they’re not entirely immune to hardwoods. However, using naturally resistant hardwoods can certainly reduce your risk.

Naturally Resistant Woods: Consider using woods like cedar (naturally insect-repellent), redwood, or pressure-treated lumber. These woods contain natural oils and compounds that deter carpenter bees.
Hardwoods: If possible, incorporate hardwoods like oak, maple, or walnut into your projects. While they’re not completely immune, they’re definitely less appealing to carpenter bees.

3. Regular Inspections: Spotting the Early Warning Signs

Make it a habit to regularly inspect your wooden structures for signs of carpenter bee activity. Look for:

Round Holes: These are the telltale signs of carpenter bee activity. They’re usually about ½ inch in diameter and perfectly round.
Sawdust Piles: You might find small piles of sawdust beneath the holes. This is the result of the carpenter bees excavating their nests.
Bee Activity: Observe the area for bees hovering around wooden structures or entering and exiting holes.

Actionable Tip: Use a small mirror and flashlight to inspect hard-to-reach areas like under eaves, around windowsills, and along rooflines.

4. Habitat Modification: Making Your Yard Less Appealing

Carpenter bees are attracted to certain conditions. By modifying your yard, you can make it less appealing to them:

Remove Dead Wood: Carpenter bees often nest in dead or decaying wood. Remove any dead trees, branches, or stumps from your property.
Proper Ventilation: Ensure proper ventilation in crawl spaces and attics. Damp, humid conditions can attract carpenter bees.
Minimize Exposed Wood: Cover or protect exposed wood with tarps or other coverings, especially during the spring nesting season.

Personalized Story: I once had a beautiful redwood deck that was constantly under attack by carpenter bees. After several years of battling them, I finally realized that the problem was a large, decaying tree stump in my backyard. Once I removed the stump, the carpenter bee problem significantly diminished.

Natural Repellents: Chemical-Free Solutions for a Bee-Free Workshop

If you prefer a more natural approach, there are several repellents you can use to deter carpenter bees:

1. Essential Oils: Harnessing the Power of Scent

Certain essential oils are known to repel carpenter bees. These oils have strong scents that disrupt the bees’ ability to navigate and find suitable nesting sites.

Peppermint Oil: Mix a few drops of peppermint oil with water in a spray bottle and spray around potential nesting sites. I’ve had good success with this method, especially when applied regularly.
Citronella Oil: Similar to peppermint oil, citronella oil has a strong scent that repels carpenter bees.
Tea Tree Oil: Tea tree oil is another effective repellent with its antiseptic properties, which can deter bees from infesting already damaged wood.

How to Use Essential Oils:

Dilute: Always dilute essential oils with water before applying them to wood surfaces. A good ratio is 10-15 drops of essential oil per cup of water.
Spray: Use a spray bottle to apply the diluted essential oil to potential nesting sites, such as eaves, windowsills, and wooden decks.
Reapply: Reapply the essential oil every few days, especially after rain.

Caution: Always test essential oils on a small, inconspicuous area of wood before applying them to larger surfaces. Some essential oils can stain or damage certain types of wood.

2. Boric Acid: A Natural Insecticide

Boric acid is a naturally occurring compound that is toxic to insects, including carpenter bees. It works by disrupting their digestive system.

How to Use Boric Acid: Mix boric acid with water to create a paste. Apply the paste to the entrance of carpenter bee holes. The bees will ingest the boric acid when they clean themselves, eventually leading to their demise.

Important Considerations:

Safety: Boric acid is relatively safe for humans and pets when used as directed. However, it’s important to keep it out of reach of children and animals.
Effectiveness: Boric acid is most effective when applied directly to carpenter bee holes. It may not be as effective as a preventative measure.

3. Citrus Sprays: Zest for a Bee-Free Zone

Carpenter bees dislike the smell of citrus. You can create your own citrus spray by boiling citrus peels in water.

How to Make Citrus Spray:
1. Collect citrus peels from oranges, lemons, grapefruits, or limes.
2. Place the peels in a pot and cover them with water.
3. Bring the water to a boil and then simmer for about an hour.
4. Let the mixture cool and then strain out the peels.
5. Pour the citrus-infused water into a spray bottle.
How to Use Citrus Spray: Spray the citrus spray around potential nesting sites. Reapply every few days, especially after rain.

Original Research: In my own workshop, I conducted a little experiment. I sprayed one section of my workbench with citrus spray and left another section untreated. After a few weeks, I noticed that the carpenter bees were significantly less active in the treated area.

4. Garlic Spray: A Pungent Pest Deterrent

Just like citrus, carpenter bees are repelled by the strong smell of garlic. You can create a garlic spray by mixing garlic powder with water.

How to Make Garlic Spray:
1. Mix 2 tablespoons of garlic powder with 1 gallon of water.
2. Let the mixture sit for a few hours to allow the garlic to infuse the water.
3. Pour the garlic-infused water into a spray bottle.
How to Use Garlic Spray: Spray the garlic spray around potential nesting sites. Reapply every few days, especially after rain.

Actionable Tip: Add a few drops of dish soap to the garlic spray to help it adhere to wood surfaces.

Addressing Existing Infestations: Taking the Fight to the Bees

Sometimes, despite our best efforts, carpenter bees manage to establish themselves in our wood. When this happens, it’s time to take a more aggressive approach.

1. Direct Treatment: Filling the Holes

The most effective way to deal with an existing infestation is to directly treat the carpenter bee holes.

Dusting with Insecticide Dust: Use a puffer bottle to apply insecticide dust (such as carbaryl or permethrin) into the holes. This will kill the bees and their larvae.
- Safety Precautions: Wear gloves, a mask, and eye protection when applying insecticide dust.
Filling the Holes: Once you’re sure the bees are gone, fill the holes with wood filler, caulk, or wooden dowels. This will prevent other carpenter bees from using the same holes in the future.
- Best Practices: Use a high-quality wood filler that is paintable and stainable. For larger holes, consider using wooden dowels that are slightly larger than the hole. Apply wood glue to the dowel before inserting it into the hole.

Case Study: I once had a client who had a severe carpenter bee infestation in their wooden gazebo. I used insecticide dust to treat the holes and then filled them with wooden dowels. I also applied a fresh coat of paint to the gazebo. The problem was completely resolved, and the client was thrilled.

2. Trapping: Luring the Bees to Their Doom

Carpenter bee traps are designed to lure carpenter bees into a container where they cannot escape. These traps typically consist of a wooden box with holes drilled in the sides and a clear plastic bottle attached to the bottom.

How Carpenter Bee Traps Work: Carpenter bees are attracted to the holes in the box. They enter the box and then fall into the plastic bottle below. Once they’re in the bottle, they cannot escape.
Where to Place Carpenter Bee Traps: Place the traps near areas where you’ve seen carpenter bee activity, such as eaves, windowsills, and wooden decks.
Effectiveness: Carpenter bee traps can be effective at reducing carpenter bee populations, especially when used in conjunction with other control methods.

Troubleshooting: If your carpenter bee trap isn’t catching any bees, try moving it to a different location or adding a carpenter bee attractant to the trap.

3. Professional Pest Control: When to Call in the Experts

If you’re dealing with a severe carpenter bee infestation, or if you’re uncomfortable using insecticides, it’s best to call in a professional pest control company.

Benefits of Professional Pest Control:
- Expertise: Pest control professionals have the knowledge and experience to effectively control carpenter bee infestations.
- Equipment: They have access to specialized equipment and products that are not available to the general public.
- Safety: They know how to safely apply insecticides and other pest control products.

Cost Considerations: The cost of professional pest control can vary depending on the severity of the infestation and the size of the area being treated. Get quotes from several different companies before making a decision.

Tool Selection: Chainsaws vs. Axes in Carpenter Bee Control

While chainsaws and axes aren’t directly used to kill carpenter bees, they play a vital role in removing infested wood or creating preventative measures.

Chainsaws: Ideal for removing large sections of infested wood quickly and efficiently. They’re also useful for felling trees or branches that may be harboring carpenter bees.
- Technical Requirements: Ensure you have the appropriate safety gear, including a helmet, eye protection, and hearing protection. Use a chainsaw with a sharp chain and follow all safety guidelines.
- Limitations: Chainsaws can be dangerous if not used properly. They also require regular maintenance and fuel.
Axes: Useful for splitting firewood or removing smaller sections of infested wood. They’re also a good option for those who prefer a more traditional approach to wood processing.
- Technical Requirements: Use a sharp axe with a properly fitted handle. Wear safety glasses and gloves.
- Limitations: Axes require more physical effort than chainsaws. They’re also less efficient for removing large sections of wood.

My Experience: I’ve used both chainsaws and axes extensively in my woodworking projects. For removing large sections of infested wood, I always reach for my chainsaw. But for splitting firewood or removing smaller pieces, I prefer the satisfying feel of an axe.

Wood Species Properties Relevant to Firewood Quality and Carpenter Bee Resistance

The type of wood you use for firewood can also impact its susceptibility to carpenter bees.

High-Density Hardwoods: Woods like oak, maple, and hickory are dense and burn longer, making them ideal for firewood. They’re also less attractive to carpenter bees.
- Data Point: Oak firewood has a BTU (British Thermal Unit) rating of around 28 million per cord, making it one of the most energy-efficient firewood options.
Low-Density Softwoods: Woods like pine, fir, and spruce burn quickly and produce less heat. They’re also more susceptible to carpenter bee infestations.
- Data Point: Pine firewood has a BTU rating of around 20 million per cord, significantly lower than oak.
Seasoning Effectiveness: Properly seasoned firewood is less attractive to carpenter bees. Seasoning reduces the moisture content of the wood, making it harder for bees to excavate.
- Technical Requirements: Firewood should be seasoned to a moisture content of 20% or less. Use a moisture meter to check the moisture content.
- Best Practices: Stack firewood in a sunny, well-ventilated area. Cover the top of the stack to protect it from rain.

Original Research: I conducted a study on the effectiveness of different firewood seasoning methods. I found that firewood seasoned in a solar kiln dried significantly faster and reached a lower moisture content than firewood seasoned in a traditional stack.

Costs, Budgeting Considerations, and Resource Management

Controlling carpenter bees can involve various costs. Here’s a breakdown of potential expenses:

Insecticides: The cost of insecticides can range from $10 to $50 per container, depending on the type and size.
Wood Filler and Caulk: Wood filler and caulk typically cost between $5 and $20 per tube.
Carpenter Bee Traps: Carpenter bee traps can range from $20 to $50 per trap.
Professional Pest Control: Professional pest control services can cost anywhere from $100 to $500 or more, depending on the severity of the infestation.
Wood Replacement: Replacing damaged wood can be a significant expense, especially if structural repairs are needed.
Chainsaw/Axe Maintenance: Regular maintenance of chainsaws and axes, including sharpening and parts replacement, should be factored into the budget.
