Building a bat house is a great weekend project that can be beneficial in helping rid your yard of unwanted mosquitoes and gnats. One bat alone can eat up to 1,000 mosquitoes a night, so you may want to consider this natural way to get rid of a large mosquito population in your yard and at the same time create a nice bat home that can be educational for young children and adults alike. Though bats are often thought of as a bad thing, they can really be a nice addition to your yard's ecosystem. Here’s how to build a simple bat house in a few easy steps:

How to Build a Bat House

Step 1 – Cut the Wood

Use your circular saw to cut 3 pieces of the plywood into these dimensions: 1 piece at 26 ½-by-24 inches, 1 piece at 16 ½-by-24 inches and 1 piece at 5-by-24 inches.

Step 2 – Create Grooves on the Back of the House

Use your pencil to make lines on the back panel of the house (the 26 ½-by-24 inch piece of plywood) ½ inch apart. Make these lines across the entire back of the house. Cut along the marked lines with the circular saw to a depth of 1/16 inch.

Step 3 – Apply Stain

Use a brush to apply the stain to the interior pieces of the plywood. Be sure to use stain and not paint, as paint will fill in the grooves. Wait for the stain to dry and proceed to the next step.

Step 4 – Cut the Firring Strips

Measure and cut the firring strips into 1 piece 24 inches long and 2 pieces at 20 ½ inches in length. Place and secure the two short furring strips on the short side of the plywood and the longer piece along the long side of the back piece.

Step 5 – Put the House Together

Take the 16 ½-by-24 inch piece of plywood and attach it to the furring strips, leaving a ½-inch gap to provide the bats with some ventilation. Next, attach the 5-by-24 inch piece directly below the top piece. There should be an exposed back area that will allow the bats to climb up, land and crawl into the house.

Step 6 – Seal the House

Use caulk to seal the joints of the bat house. Place a 1-by-3 inch board on the roof and secure with screws. Paint or stain the exterior of your new bat house. When it is dry, mount it on a building or a tree in your yard and wait for the bats to come.

This easy project can be very rewarding when bats move into your new bat house. Try it out and experience the most easy form of bug control there is.
