bat houses

Yesterday I began preparing materials for my students to make bat houses. While we could spend days with students designing their own bat houses, in this case it's important that we adhere to science and make use of designs that have already been proven in use. The four chamber bat house offers the opportunity for bats to seek warmth by congregating together and to move around inside to the spot they find most comfortable.

We have a large colony of bats nesting in vents under the eves in one of our school buildings and while it can be a challenge to lure a colony of bats to a new location, luxurious new bat houses carefully engineered for their safety and happiness may help. Experimental designs my not.

A good source of information about bats is the Bat House Builder's Handbook, by Merlin D. Tuttle.

One of the tedious jobs in preparing the materials for making bat houses is that of grooving the parts that must be textured for the bats to get a good grip on the insides of the box and that allow them to climb around inside. I've been doing the grooving using the table saw in the school wood shop. We have been enjoying relatively bug free evenings on our deck this summer, and for that, I thank our bats.

The drawing shows the design of the bat houses we're making and detailed plans are available in the book.

Make, fix and create.
