This instructable is about how to build a Bat House. Below is the list of supplies that you will need for this project. It is better if the wood is not pressure treated but if that is the only wood you have access to it is okay to use it.
- Wood(for best results use 3/4 inch thick
- Screws or Nails
- Electric Saw
- Router or chisel

Step 1: The Roof
The Roof is one of the most important parts of the Bat House because it keeps the inside dry and it is what the bats will cling to. Start by cutting out a 6.75 inch by 5.5 inch rectangle. Then choose a side to be the inside of the house. Once you have chosen a side you want to either use the router or the chisel and carve out little grooves for the bats to cling to when they sleep. They need the grooves because they need something to hold onto since the wood is too smooth for their claws to grab onto. This will be the only step that you will use the router or chisel so you can put it away after you are done with this step.
Step 2: The Back Wall
The next part that we will build is the back. The back helps keep the bats protected from the wind and predators. This time cut a piece of wood to the dimensions of 5.5 inches by 11.75 inches. Now you want to sand the wood so that the bats do not hurt themselves.
Step 3: The Front Wall
The front wall also protects the bats from the wind and predators by hiding them. This wall is smaller than the back wall so that we can add an opening at the bottom. Now you want to cut a piece of wood into a 5.5 inches by 6.25 inches. You also want to sand this wall and any future walls.
Step 4: Slanted Wall
The slanted wall helps enclose the bottom of the bat house but leaves some room for the bats to get in. This wall helps protect the bats from predators by keeping the entrance small so that larger animals can not get inside. This piece of wood should be 5.5 inches by 3 inches.
Step 5: Side Walls
The side walls helps add support and protection to the house. Now you want to cut two 5.5 inches by 11.75 inches rectangles. Once you have cut them you want to measure 45 degrees from one of the corners inward and draw a line from the corner to the side following the 45 degree angle. After you have drawn the line you want to make a cut along the line. This helps with aesthetics and makes it easier for the bats to fly in.
Step 6: Putting It Together
Finally you can put everything together. First we want to attach the side walls and the back wall together. To do this you want to put a nail or screw at the top and the bottom so that it is attached at both ends. Next you attach the front wall to the side walls. You do this by aligning the front wall at the top of the side walls and nail or screw it in from there. Then you attach the slanted wall. This wall will be aligned with the downward slant of the side walls at the base of the front wall. Once it is aligned you can proceed to attaching it. Finally we attach the roof. This part is simple enough, you want the roof covering the entire opening at the top before you screw it in.
