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

03

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:

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

  • Inspect Your Home: Look for round holes or damaged wood.
  • Seal Holes: Fill them with caulk or wood putty.
04

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.
05

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.
06

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.
08

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.
09

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.
10

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.

11

When to Call a Professional

12

Signs of a Severe Infestation

  • Multiple round holes in wood
  • Piles of sawdust (called frass) beneath holes
  • Lots of carpenter bees flying near your home
13

Why Call a Professional?

  • Experts use stronger treatments like insecticidal dust injected into tunnels.
  • They can identify all nesting areas and provide long-term solutions.
  • Professionals offer follow-up services to prevent future infestations.
14

Finding the Right Pest Control Company

  • Look for experienced companies with good reviews.
  • Ask for a detailed treatment plan and references before hiring.
15

Monitor and Maintain Your Home

16

Regular Inspections

Check your property twice a year, especially in early spring and late summer when carpenter bees are most active. Look for new holes, sawdust, or bee activity.

17

Use Bee Traps

Set up traps designed for carpenter bees to monitor their presence and reduce their population.

    Alex was great! Very professional and explained the whole process before doing any work. We had a wasp nest in our wall, getting in through a seam between our brick and siding. I thought it would be a costly problem, but it was taken care of in about 15 minutes.

    I am very pleased with the work of Planet Friendly Pest Control. I had a large wasp nest in the garage and they came out to treat it the same day! The process was clear and professional. I was told the price when I called and they didn't try to upsell me on a monthly or quarterly contract. As mentioned above, they came out the same day I called and they texted me when they were on their way. They treated the nest and then came back a week later to confirm it was taken care of and removed the nest. It's now been a couple of weeks since the initial visit and no sign of new wasps! I would not hesitate to use them again.

    I want to sincerely thank Planet Friendly Pest Control and its owner, Gene Wright, for their immediate response and action to deal with a hive of Bald Face Hornets who, unbeknownst to me, had taken home in a fair size shrub at the back of my house. As I attempted to trim the shrub, I was swarmed by Hornets and stung 8 or 9 times before I could get to safety. I left my tractor and tools in a hurry and was afraid to retrieve them until the bee issue was addressed. Again, PFPC responded quickly and allowed me to get my tools and continue my recovery from the bee stings. I considered the price to be very fair for the treatment of the issue at hand and the sharing of knowledge to avoid further such mishaps. I will only call PFPC when in need of pest control.

    Really appreciate Roger coming out to the house to not only treat for common insects that like to make their way into the house (regularly scheduled maintenance), but also exterminate a hornet nest we found on our deck this last week. Great service, arrives on schedule (and sends a text with arrival time when he’s on his way), and most importantly - no critters coming inside my house - or hornets potentially stinging us. Recommend Planet Friendly Pest Control to anyone looking for an exterminator.

    Gene Wright came highly recommended by multiple neighbors. He came out the same day I called and showed great knowledge about our mouse problem! Gene was responsible, knowledgeable and a delight to deal with. We highly recommend Planet Friendly Pest Control.
