  • Controlling Population: In some areas, squirrels may reproduce at a fast rate and become a nuisance for homeowners. You can help maintain their population and prevent them from invading your home by providing a designated shelter.
  • Aesthetics: Squirrel boxes can also add beauty to your backyard or garden. Various designs are available, so you can choose one that complements the overall aesthetic of your outdoor space.
  • Educational Tool: Building a squirrel box with children can be an academic activity that teaches them about wildlife conservation and the importance of coexisting with animals in their environment.

What Will You Need?

To build a squirrel box, you will need the following materials:

  • A sturdy wooden box or birdhouse (can be purchased from a hardware store or repurposed from old materials)
  • Screws
  • Drill
  • Saw
  • Sandpaper
  • Hammer and nails
  • Outdoor paint or sealant (optional)

Once you have gathered all the necessary materials, you and your children can begin the fun and educational activity of building a squirrel box.

10 Easy Steps on How to Build a Squirrel Box

Step 1. Prepare Your Workspace

Ensure you have a clean, flat surface to work on, such as a sturdy table or workbench. Remove any clutter or debris to create a safe area for using tools. Gather all your materials and tools, placing them within easy reach to avoid disruptions. If you’re working with children, explain the importance of workspace safety and supervise their activities to ensure a safe and enjoyable experience.

 Enjoyable Experience

Step 2. Measure and Cut the Wood

Use a measuring tape to carefully measure the dimensions of each piece of wood required for the squirrel box. Refer to your design or template for precise measurements, ensuring all pieces will fit together without gaps. Mark the measurements on the wood with a pencil to guide your cuts. Using a saw, cut along the lines you’ve marked.

A hand saw or jigsaw works well for this task, but ensure you follow proper safety precautions, such as wearing protective goggles and keeping your fingers away from the blade. Double-check all pieces once cut to confirm their sizes match your plan. Sand down the edges of each piece after cutting to remove any splinters and create smooth surfaces that will be safe for the squirrels.

Step 3. Smooth the Edges

To ensure the squirrels’ safety and improve your project’s overall look, it’s essential to smooth the edges of each wooden piece. Start using coarse sandpaper, such as 80-grit, to remove rough spots or jagged edges. Then, switch to a finer grit, like 120 or 150, to create a polished finish. Pay close attention to corners and edges, as these are often the roughest areas. If you have access to an electric sander, it can speed up the process and provide a more even finish. Wipe the surfaces with a damp cloth afterward to remove dust and debris.

Step 4. Drill an Entrance Hole

Using a drill, create an entrance hole that is appropriately sized for the intended occupants of your wooden project, such as birds or small animals. A typical hole size for birdhouses ranges between 1 to 2 inches in diameter, depending on the species you aim to attract. Carefully measure and mark the placement of the hole on the front panel before drilling to ensure accuracy. Use a spade bit or hole saw for a clean, precise cut. Be sure to drill slowly and steadily to avoid splintering the wood. Once the hole is complete, sand the edges to make them smooth and safe for the occupants.

Step 5. Attach the Panels

Using wood screws or nails, carefully attach the panels of the birdhouse. Start by connecting the side panels to the back panel, ensuring all edges are aligned. Next, attach the front panel, making sure the entrance hole is positioned correctly. Secure the bottom panel in place, leaving the top panel for last.

If the birdhouse is designed with a hinged roof for easy cleaning, attach one side of the roof with hinges and ensure it opens and closes smoothly. Double-check all connections to ensure the structure is sturdy and free of gaps, as this will provide a safe and durable home for the birds.

Panels of the Birdhouse

Step 7. Add the Back and Front

Begin by attaching the back panel to the sides of the birdhouse. Align the edges carefully and secure it with nails or screws, ensuring it is firmly in place. Next, position the front panel, which typically has the entrance hole pre-cut. Ensure the entrance hole is appropriate for the type of birds you aim to attract. Attach the front panel to the sides and the bottom, checking that there are no gaps or weak points. Proper alignment and secure fastening here are essential to create a sturdy and safe bird environment.

Step 8. Install the Roof

Carefully place the roof panel on top of the birdhouse, ensuring it fully covers the structure to protect it from rain and other elements. If the roof consists of two slanted pieces, align them so they meet securely at the peak. Use nails or screws to attach the roof to the sides and back panels firmly. Be sure there are no gaps where water might seep in, as this could make the birdhouse unsuitable for its inhabitants. For added durability, consider treating the roof with a weather-resistant sealant to ensure long-lasting protection against harsh weather conditions.

Step 9. Apply Paint or Sealant

To enhance the appearance and durability of your birdhouse, apply a coat of non-toxic, outdoor-safe paint or sealant. Choose colors that blend naturally with the environment to avoid startling potential bird inhabitants. When painting, cover all exterior surfaces, including edges and corners, while leaving the interior unpainted. This prevents harmful fumes from affecting the birds. If using a sealant, opt for a weatherproof, bird-safe product to protect the wood from moisture and sunlight.

Step 10. Create Ventilation and Drainage Holes

Proper ventilation and drainage are crucial for maintaining a healthy and safe environment inside the birdhouse. To create ventilation, drill small holes near the top of the birdhouse walls just below the roofline. These holes should allow air to circulate and prevent overheating during warmer seasons. Add a few small holes near the bottom of the birdhouse floor for drainage. These will help any accumulated rainwater escape, keeping the interior dry and comfortable. Ensure the holes are not too large to prevent predators or pests from entering.

 Are Not Too Large

By following these tips, you can create a safe and comfortable environment for birds to call their home.

5 Things You Should Avoid

  1. Using Toxic Materials

Avoid using treated wood, paints, or finishes containing harmful chemicals. These substances can be toxic to squirrels, especially when they chew on the box, which they often do. Always opt for natural, untreated wood.

  1. Placing the Box in Unsafe Locations

Do not place the squirrel box in areas easily accessible to predators, such as on low branches or near open areas where predators can spot them. Ensure it’s high enough and located in a secure, sheltered spot.

  1. Making the Entrance Hole Too Large or Too Small

A hole that is too large may allow predators or other animals to invade the box, while a too small hole may prevent squirrels from comfortably entering or exiting. Aim for an entrance hole with an appropriate diameter, typically around 3 inches.

  1. Neglecting Proper Ventilation

Failing to include adequate ventilation holes can make the squirrel box too hot or humid, which may deter squirrels from using it. Always ensure proper air circulation to maintain a suitable environment.

  1. Skipping Regular Maintenance

Building and neglecting a squirrel box can lead to debris buildup, mold, or structural damage. Avoid this by checking it periodically, cleaning it as needed, and repairing any damage to keep it safe and habitable.
