While in many cases it is not necessary to paint or stain a Lone Star Woodcraft bat house, doing so can sometimes help to maintain optimal temperatures in cooler/northern climates. Cooler areas, such as the northern U. S. and Canada, may benefit from a darker color to help absorb more warmth from the sun. Never paint or stain inside the bat house or the landing pad, as the bats need a rough natural surface to hang from when they are roosting or landing, and this may be compromised by paint or stain. Also, keep in mind that cedar will naturally darken in color over time. See our Region Map for staining/painting recommendations.
