How to Get Rid of Carpenter Bees: Safe and Effective Methods

Carpenter bees might look harmless, buzzing peacefully around your garden, but they can cause serious damage to wooden surfaces over time.

Unlike honeybees, these bees don’t build hives — they drill holes into wood to create tunnels for nesting. The result? Unsightly holes, wood dust, and structural damage if ignored.

Here’s everything you need to know about how to get rid of carpenter bees safely — and how to keep them from coming back.

🪵 1. What Are Carpenter Bees?

Carpenter bees are large, black-and-yellow insects that resemble bumblebees.

However, unlike bumblebees, they don’t live in colonies — they prefer to live alone.

Female carpenter bees bore small, round holes (about ½ inch wide) into wood to lay their eggs. Over time, these tunnels can weaken beams, decks, fences, and even window frames.

🐝 2. Signs of Carpenter Bee Infestation

Look out for these common warning signs around your home or garden:

Perfectly round holes in wooden surfaces (often under eaves, decks, or railings)

Fine sawdust near holes or on the ground

Buzzing bees flying around the same area repeatedly

Woodpeckers pecking at wood (they’re often after bee larvae!)

If you notice any of these, it’s time to take action before the damage spreads.

⚙️ 3. How to Get Rid of Carpenter Bees Naturally

Carpenter bees are important pollinators, so it’s best to remove them safely instead of harming them. Here are some eco-friendly ways to deal with them:

🌿 a. Use Citrus Spray

Carpenter bees dislike the smell of citrus.

Boil orange or lemon peels in water for 10–15 minutes, cool it, pour into a spray bottle, and spray directly into their holes or around affected areas.

🌿 b. Apply Essential Oils

Mix tea tree, lavender, or almond oil with water and spray near bee holes.

The strong scent repels bees without causing harm.

💨 c. Hang a Carpenter Bee Trap

You can buy or make simple wooden bee traps that lure the bees inside.

Once trapped, they can’t escape and eventually die.

Hang traps near affected wood areas — especially under decks and roof edges.

🔦 d. Seal the Holes at Night

Carpenter bees are inactive after sunset.

Wait until night, ensure bees have left, then seal holes with wood putty, caulk, or steel wool.

Finally, repaint or varnish the surface — bees rarely drill into painted wood.

🔊 e. Use Sound or Vibration

Carpenter bees dislike constant noise.

Playing music or keeping a small vibrating device near their nest can encourage them to leave.

🚫 4. How to Prevent return of Carpenter Bees

Prevention is key to long-term protection. Follow these steps:

1. Paint or stain wood — bees prefer bare wood.

2. Use hardwoods like oak or mahogany for outdoor furniture — they’re harder to drill.

3. Plug old holes and repaint them.

4. Install vinyl or aluminum trim on vulnerable surfaces.

5. Use decoy nests — fake wasp nests can discourage bees from settling nearby.

⚠️ 5. When to Call a Professional

If the infestation is large or near structural wood (like beams, decks, or attics), it’s best to call a pest control expert.

They use safe treatments and can check for deeper damage that may not be visible from the outside.

🌸 6. Are Carpenter Bees Dangerous?

Generally, no — male carpenter bees can’t sting, and females rarely do unless provoked.

However, they can be territorial and intimidating when buzzing near you.

Their real threat lies in the damage to wooden structures, not humans.

🌼 Final Thoughts

Carpenter bees may be skilled builders, but you don’t want them remodeling your home!

With natural repellents, sealing techniques, and preventive maintenance, you can keep these buzzing carpenters away without harming them or the environment.

Remember — prevention is easier than repair.

Protect your wood today, and your home will thank you tomorrow. 🪵🐝
