Building Projects

Bat house

This year for Christmas, we built my dad a bat house. Well, it started off as me building my dad a very simple, single chamber bat house. We found the design for this bad boy here. At about two inches deep, this skinny structure can hold quite a few bats. But… while I was in the process of building this modest structure, Yukon came outside to see how I was faring with using the circular saw to score the bat “landing pad.” Jigsaws, table saws, and miter saws are all fine by me. But when it comes to circular saws, I get a little shy. Within sixty seconds of his observations of the bat house, he said, “Let’s make this into a triple chamber bat house.” So our hour-long project turned into a three hour project. But I have to admit, it did turn out pretty nice.

The design we used is for a single bat chamber house, but it adding two extra chambers with some scrap wood we had laying around was straightforward. (When you look at the plans linked above, just add two more replicates of the front, outward facing wall, with 1″x2″ strips in between each one. Just make sure to add the grooves in the plywood facing outward so the bats can climb up into the front two chambers. We also added vents in each of the chamber walls.) We used the paint type they recommended and left it white for now since we live in the south (light to medium colored).

Bat guano is some of the best fertilizer around. We looked it up on the internet; it can cost upwards of $80 for 20 pounds, and our whole project probably cost around $30-40 if you include the cost of the scrap wood we had, a can of latex paint and some caulk. Why not give the gift that keeps on giving?

Check out the ideal place to hang your bat house here. This link says you can mount them to a pole, but I’ve read it’s better to mount them to an actual building, at least 15 feet above the ground.

 

Cut List for Our Modified Three Chamber Bat House

Plywood:

  • 26.5″ x 24″ (back), you will need to line this with grooves
  • 3 each of 16.5″ x 24″ (front walls with vents), you will need to line 2 of these with grooves
  • 3 each of 5″ x 24″ (front walls with vents), you will need to line 2 of these with grooves
  • 24″ x ~10″ (roof)

Furring strips (1″x2″s)

  • 3 each of 24″ length (top furring strip)
  • 6 each of 20.5″ length (side furring strips)
