How to Build a Bat House

If the idea of putting up with pesky little bugs that make your life miserable is actually driving you up the walls, and you cannot stand the overbearing smell of synthetic pesticides; you are in for a treat. A simple bat house project can take care of these pesky problems and ensures that an evening spent on your porch is a delectable affair that is not marred by insect bites.

Putting up a bat house in your property drastically reduces the number of bugs menace in their vicinity. Bat houses are small, unobtrusive structure that can blend perfectly with your house exteriors – if they are well put together with excellent skills.

Thanks to the woodworking program, Ted’s Woodworking that provides detailed step by step instructions on how to a build bat house, you can easily create a magnificent structure to shelter bats on your property. I have outlined below how I was able to follow the plans and step by step how I built my own bat house.

The very first step involves getting together all the required materials: cedar wood planks, exterior plywood, mesh, saws, drilling gun and bits, screwdrivers, and a caulking agent.

Step 1: Create the backboard

Cut out a rectangular piece from the plywood depending on the bat house plan you like and want to put up. Leaving a gap of about an inch around the edges, staple the mesh on the inside bit of the backboard. The mesh provides hook points on which the bats can hook upon while resting during day times. The backboard projects beyond the covering front part to provide a landing bay for the bats when they need to gain entrance into the house.

Step 2: Create the front piece

Unlike the backboard, the front part of a bat house project comprises of two plywood blocks that are joined such that they leave a gap measuring about half an inch between them. The gap serves as the ventilation shaft to ensure fresh air circulates within the house.

If you require more detailed examples and blueprints, refer to the complete guide at Ted’s Woodworking where a bat house tutorial is included and explains how to create a landing pad to ensure that bats land safely and have convenient access to the house.

The front side also features an entry barrier that ensures a haven for bats and promotes the creation of a maternal colony. After measuring out the required front pieces join them to the sidings of the bat house project by caulk, screws or nails and create a perfect fit.

Step 3: Create the sidings

The sidings determine the width and the capacity of the bat house and are preferably made from cedar planks for the longevity of the bat house project. Ensure the upper end of the sidings features an edge beveled at 30-degrees to ensure that rainwater runs off the roof quickly.

After creating the suitable sidings, join them to the front piece by either drilling holes or driving screws into them or through the good old fashioned nails and hammer. For an extra tight and strong bond apply some caulk on the sidings before driving the screws.

Step 4: Strengthen the joints

Apply a caulking agent to all the joints to prevent water from seeping into the bat house and ruining it. Allow plenty of time after applying caulk for the bat house to dry thoroughly and avoid any loose joints. This guide explains how to apply caulk in more detail to your bat house as well as the best caulk types for such a bat house project.

Step 5: Add the roof

The roof, which is slanted at 30-degrees, should be the last component of your bat house to fall into place. The slant ensures that water does not accumulate on top and start seeping into the bat house. Line all the sides with a caulking agent before fastening with screws or nails.

Be sure to hang out the newly completed bat house project about 15 – 20 feet off the ground for easy access by the bats and to keep off predators such as raccoons, large birds, and cats. Below is the completed DIY bat house.
