Carpenter Bee Houses: The Benefits of Providing a Home for These Pollinators

What are Carpenter Bees and Why are They Important?

Carpenter bees, also known as wood bees, are large, solitary bees that get their name from their ability to drill into wood in order to create their nests. While they can cause damage to structures such as wooden decks and fences, they are also important pollinators for a variety of flowers and crops. Providing a carpenter bee house can not only help to reduce damage to your own property, but it can also support the population of these beneficial insects.

How to Build a Carpenter Bee House

If you want to attract carpenter bees to your yard, one of the best things you can do is build a carpenter bee house. These can be purchased pre-made or you can make your own using a few simple materials.

To make your own carpenter bee house, you will need:

  • A piece of untreated wood, at least 6 inches wide and 12 inches long
  • A drill and 3/8 inch drill bit
  • Sandpaper
  • A saw (optional)


  1. Start by drilling holes into the piece of wood. The holes should be about 3/8 inch in diameter and spaced about 3 inches apart. Make sure to drill the holes at least 1 inch deep.
  2. Smooth the edges of the holes with sandpaper to make it easier for the bees to enter and exit.
  3. If desired, you can cut the piece of wood into a more attractive shape using a saw.
  4. Hang the carpenter bee house in a sunny location, preferably facing south or southeast.
  5. Sit back and watch as the carpenter bees move in and begin to use the house.

Tips for Maintaining Your Carpenter Bee House

Carpenter bees are generally low maintenance, but there are a few things you can do to ensure that your carpenter bee house stays in good condition:

  • Avoid using treated wood, as the chemicals can be harmful to the bees.
  • Check the house regularly for any damage or wear and make repairs as needed.
  • Clean out the house annually by removing any old nesting material and debris.
  • Provide a shallow dish of water near the bee house to help the bees stay hydrated.

The Benefits of Having a Carpenter Bee House

In addition to supporting the population of these important pollinators, having a carpenter bee house can also have several other benefits:

  • Attracting carpenter bees to your yard can help to pollinate your flowers and garden plants, leading to healthier and more abundant growth.
  • Providing a home for carpenter bees can help to reduce the likelihood of them drilling into the wood on your home or other structures.
  • Carpenter bees are generally docile and not aggressive, making them a safe and enjoyable addition to your yard.

By building and maintaining a carpenter bee house, you can not only support these important insects, but also enjoy the many benefits they bring to your yard and garden.
