Build Your Own Bat Box

Building a bat house is a simple project that can be fun to do with your children. It's a great way to learn about bats and instill a sense of environmental stewardship.

This box is a large stacked box built with the hopes of attracting a larger colony. It requires three quarters of a sheet of half inch plywood.   I greatly encourage the use of scrap plywood.  If you see some roofers re-decking a house roof, ask them for some scraps, what they give to you they don’t have to haul away.

 

  1. The Back.  Cut one piece 16" wide by 24" long

  2. Centers. Cut 3 pieces 16" wide by 18" long

  3. Set the depth of your circle saw no more then 1/4" and cut a series shallow cuts(kerfts) across and diagonally on the plywood.  The back and one center need only be kerfted on  one side. The other two pieces need both sides cut.  These kerfts are important because they provide a gripping points for the bats.

  4. Cut the sides.  Two pieces of plywood 4" wide each having an angled top having a length of 18" on one side 20" on the other.

  5. Cut your spacers out of 3/4" stock 3/4" x 15". These will go between each layer of the center boards.

  6. Stain or paint all the parts a dark color. This will help protect the pieces from the weather, and the bats prefer dark colors.

  7. Time to start putting it together.  First attach the sides to the back.  Then alternate spacers and center panels. Finish with the  top.

  

Bats

·         Bats can eat up to 3000 mosquitoes a night as well as other insects. Attracting bats to your area is a good way to cut down on the insect population.

o   In our area we have small brown bats and large brown bats. 

o   Are Bats dangerous? The truth is, there are only six species of bats known to have transmitted the rabies virus to humans. The most common bat house bat throughout most of the U.S., the little brown bat (Myotis lucifugus), has never been implicated in a human rabies case, and the next most common, the big brown bat (Eptesicus fuscus), has been implicated in only one case. Most other cases stem from non-colonial, tree roosting species unlikely to ever use bat houses.

·         Bat houses should be placed in an area that gets at least 7 hours of direct sun light a day.

·         The bat house should be mounted at least 15’ off the ground on a pole or the side of a building.

·         Paint the house a dark color to absorb heat.  Baby bats like it very worm.
