What is the recommended gap dimension for bat management?

The recommended gap dimension for bat management is 1/4 x 1 1/2 inches because this size provides an optimal entry point for bats while still being small enough to deter larger animals. Bats generally require narrow openings to access roosting sites, and the specified dimensions allow for easy ingress and egress. This measurement strikes a balance between facilitating bat access and minimizing openings that might encourage other pests or wildlife to enter.

Using a gap of 1/4 x 1 1/2 inches also helps target specific bat species that are adapted to use such spaces. This dimension aligns well with the natural behaviors of many bats, which often roost in crevices and tight spaces. Therefore, this choice effectively supports bat conservation strategies while ensuring control over their nesting environments.
