Designed by a leading owl researcher, The Barn Owl Box is the first lightweight, long-lasting plastic nest box for attracting barn owls. It features a landing ledge, rain guard, 5.5" entrance hole, removable front for easy cleaning, and an acrylic window for viewing eggs and chicks. Dimensions are 26" L X 18" H X 18" W.
Integrated pest management takes a broad, multidisciplined approach to rodent control. Barn owls can assist such rodent control programs by harvesting large numbers of rodents throughout the year.
This allows other approaches, such as trapping,or poison's to be more effective.
This Barn Model is designed to fit into the exterior wall of either a metal or wooden barn. It provides a nesting site for owls without allowing the owls or pest species access to the barn interior.
Weighs 14 pounds.
