How to Get Rid of Carpenter Bees: A Complete Guide
Learn how to get rid of carpenter bees safely and effectively. Discover methods to protect your home from these wood-boring pests and prevent future infestations.
Quick Summary
To get rid of carpenter bees, identify their nests, often recognized by perfectly round holes in wood. You can use methods like trapping, applying borate-based treatments, or sealing their entry points after they've left or are inactive. Prevention is key to deterring future infestations and protecting your wooden structures.

🛒 What You Need
- Carpenter bee traps
- Borate-based insecticide dust or liquid
- Dust applicator or spray bottle
- Wood putty or wooden dowels
- Exterior caulk and caulk gun
- Safety glasses
- Gloves
- Ladder (if needed)
📋 Steps
Identify Carpenter Bee Activity
Locate areas of carpenter bee activity by looking for perfectly round, dime-sized holes drilled into soft, unfinished wood, such as eaves, fascia boards, deck railings, or siding. You may also see sawdust-like frass accumulating below the holes, indicating active tunneling. Confirm they are carpenter bees and not other bee species by their shiny, black abdomens, unlike fuzzy bumblebees.
Choose Your Treatment Method
Decide between using carpenter bee traps, insecticides, or a combination of both. Traps offer a non-toxic solution, luring bees into a collection chamber. Insecticides, typically borate-based dusts or liquids, provide a more direct approach by treating the existing tunnels. Consider the extent of the infestation and your comfort level with pesticides.
Apply Targeted Insecticide (Optional)
If using an insecticide, carefully apply a borate-based dust or liquid directly into each carpenter bee hole using a dust applicator or spray bottle. Do this in the evening when bees are less active and likely inside their tunnels. This treatment will kill bees that come into contact with it, including larvae and eggs within the tunnels.

Install Carpenter Bee Traps
Mount carpenter bee traps near areas of known activity, especially under eaves or on deck structures where bees are frequently seen. Position the traps where they will intercept bees flying around the damaged wood. The traps are designed to mimic a bee's natural nesting site, luring them inside where they become trapped.
Seal and Repair Damaged Wood
After you've treated the tunnels and are confident the bees are gone or trapped, seal the holes. You can fill smaller holes with wood putty or caulk, or insert wooden dowels glued in place for larger tunnels. This prevents new bees from using old tunnels and helps restore the integrity of your wooden structures. Wait at least 24-48 hours after insecticide application before sealing.
Implement Preventive Measures
To deter future infestations, paint or stain all exposed bare wood surfaces. Carpenter bees prefer untreated wood for drilling. Consider using hardier wood types like cedar or redwood for new constructions or repairs, as these are less attractive to the bees. Regular inspection of your property can help catch new activity early.
💡 Tips & Tricks
- Treat carpenter bee nests in the late evening or early morning when bees are less active and more likely to be inside their tunnels.
- Paint or stain all exposed wood surfaces, as carpenter bees prefer to bore into unfinished wood.
- Consider using essential oils like citrus, almond, or tea tree oil as natural deterrents on wood surfaces, reapplying regularly.

⚠️ Warnings
- ⚠️ Always wear protective gloves and safety glasses when handling insecticides.
- ⚠️ Read and strictly follow all instructions and safety warnings on pesticide labels.
- ⚠️ Never plug carpenter bee holes while bees are actively nesting inside, as this can force them to create new exit tunnels, potentially deeper into your wood.
- ⚠️ Avoid confusing carpenter bees with beneficial pollinators like bumblebees or honey bees; carpenter bees have shiny, hairless abdomens.

❓ Frequently Asked Questions
How do you get rid of carpenter bees?
You can get rid of carpenter bees by treating their tunnels with borate-based insecticides or by installing specialized carpenter bee traps. After treatment, seal all existing holes to prevent re-infestation and protect your wood from further damage.
How to get rid of wood bees?
Wood bees, also known as carpenter bees, can be eliminated by applying insecticide dust directly into their entry holes or by setting up traps designed to lure them away. Sealing the holes once they are inactive is crucial for long-term control and preventing new bees from using old tunnels.
How to get rid of bees outside that are carpenter bees?
To get rid of carpenter bees outside, focus on treating the wooden structures they are infesting. Use traps or insecticides on deck railings, eaves, or fascia boards, and then repair and seal the damaged wood to prevent them from returning to the same spots.
When is the best time to treat carpenter bees?
The best time to treat carpenter bees is in the late evening or early morning when they are less active and more likely to be inside their tunnels. Early spring is also ideal for preventative measures and setting traps before new generations emerge.
What attracts carpenter bees to my home?
Carpenter bees are primarily attracted to soft, unpainted, or unstained wooden surfaces, which they use to bore tunnels for nesting. Common targets include cedar siding, deck railings, eaves, and fascia boards, as these provide easy access for drilling.
Are carpenter bees dangerous?
Carpenter bees are generally not aggressive and rarely sting unless directly provoked or handled. While their sting is painful, the primary danger they pose is structural damage to your home over time, as their tunneling can weaken wooden components.
Do carpenter bee traps really work?
Yes, carpenter bee traps are an effective, non-toxic method for reducing carpenter bee populations. They are designed to mimic a natural nesting site, luring the bees into a collection chamber from which they cannot escape, providing continuous control.
