Carpenter bees are insects that look like bumblebees. Unlike bumblebees that live in the ground, carpenter bees like to nest in wooden structures like fences, decks, and house siding.

Although they can cause some minor damage to wood, they are usually not aggressive and rarely sting.

Building a bee house for them can help redirect their nesting habits to a more appropriate place while also benefiting from their pollination activities.


Where is The Best Place to Build a Carpenter Bee House

Before you start building your carpenter bee house, you have to choose the right location for it. Carpenter bees like places with lots of sunlight and protection from the wind and rain.

  • Scrap boards/planks: These will serve as the main structure of the bee house.
  • Logs: Go for logs with suitable lengths to provide nesting tunnels for the bees.
  • Nails and Hammer: You need this for securing the boards and logs together.
  • Drill or Drill Press: Needed for drilling holes of various sizes.
  • Saw: A chop, miter, slide, or circulating saw will help you cut the boards to size.
  • Sandpaper: If you want a polished finish, sandpaper can be used to smooth the surfaces.

Step 1: Cutting the Blocks to Size

With the materials ready, it’s time to start building your bee house. start by cutting the boards and logs to the size you want. Make sure that the length of the logs is approximately the same as the depth your drill bit can reach.

Cutting the boards into suitable lengths will depend on the design you want and the available space for the bee house.

Safety should always be a priority, so don’t forget to wear ear protection and consider eye protection as well when operating loud saws.


Step 2: Drilling the Holes

Now comes the important step of making nesting tunnels for the carpenter bees. Use a drill or drill press to carefully make holes in the wooden blocks.

Go for at least 16 holes, with different sizes to fit various bee species. You don’t need to follow a specific pattern, but space the holes out so each bee has enough room to nest comfortably.


Step 3: Assembling the Bee House

With the holes drilled, it’s time to assemble the bee house. Start by arranging the boards and logs to create the structure of the house.

Attach the boards to the logs, to ensure a secure and stable construction. You can use nails and a hammer to fasten the pieces together.

As you assemble the house, be mindful of not obstructing the drilled holes. The goal is to provide a safe and inviting environment for the bees to nest.


Step 4: Adding the Finishing Touches

Your carpenter bee house is coming together at this point. Although not necessary, you might want to add some final touches to enhance its appearance. Sanding the surfaces can make the bee house look smooth and polished.

However, refrain from using paint, stain, or any chemicals on the holes as bees prefer natural, untreated wood. By keeping the inside of the holes as natural as possible, you improve the chances of attracting carpenter bees.


Step 5: Installing the Bee House

With the bee house fully assembled, it’s time to find the ideal spot for installation. Mount the bee house on a sturdy wooden structure like a post, tree, or tall fence.

Make sure it’s securely attached to withstand wind and weather. Place the bee house where it gets plenty of sunlight and is protected from the elements. When you choose the best installation spot, you give them the best living conditions.


Step 6: Maintaining the Bee House

After placing your carpenter bee house, you need to maintain it to keep it in good condition and make it still attractive to bees.

Regularly check the house for damage like loose boards or cracks, and fix them promptly to prevent bees from leaving.

You might also want to clean the bee house in winter to remove debris and pests. Maintaining the bee house will ensure it is a welcoming home for carpenter bees for years to come.
