Comprehensive Guide to Keeping Carpenter Bees Off Your House

Introduction

Carpenter bees may look like bumblebees, but they can be a big problem for homeowners. These bees dig holes in wood to make nests, which can weaken wooden structures over time. If you live in Southern Maryland or Northern Virginia, carpenter bees could be damaging your home or outbuildings. Learn how to protect your property with these simple prevention and control tips.

 

How to Keep Carpenter Bees Away

1. Seal Off Entry Points

Carpenter bees prefer to nest in exposed wood, like eaves, decks, and fascia boards. Here’s how to stop them:

• Inspect Your Home: Look for round holes or damaged wood.
• Seal Holes: Fill them with caulk or wood putty.

Protect Wood: Paint or varnish exposed surfaces. Treated or painted wood is less attractive to carpenter bees.

2. Treat Wood Properly

• Use Sealants or Paint: Add a fresh coat of paint or wood sealant to make surfaces less appealing.
• Try Borate Wood Preservatives: These treatments protect untreated wood and stop bees from burrowing.

3. Add Physical Barriers

• Install Screens: Place fine mesh screens over vents, soffits, and other openings.
• Upgrade Materials: Replace wood with bee-resistant options like vinyl or aluminum siding.
• Use Insect Netting: Cover vulnerable wood during the peak spring season.

Reduce Bee-Friendly Conditions

4. Keep Up with Maintenance

• Repair cracks or holes in wood.
• Replace weak or rotting wood.
• Maintain a regular schedule to check and treat wooden structures.

5. Control Moisture

Excess water weakens wood, making it easier for carpenter bees to bore through.

• Fix Drainage Issues: Keep gutters clear and water flowing away from your home.
• Improve Ventilation: Ensure proper airflow to reduce moisture.

6. Smart Landscaping

• Plant Bee-Repellent Plants: Add citronella, eucalyptus, or mint around your home.
• Clear Woodpiles: Keep logs, stumps, and dead trees far from your house.

Use Preventative Products

Apply commercial products like insecticidal sprays or dusts with active ingredients such as permethrin or cyfluthrin. Follow the product’s instructions for safe and effective use.
