The Tomahawk One-Way Exclusion Door for Squirrel (Model E40) is a humane and effective solution designed to help homeowners, property managers, and wildlife control experts exclude squirrels from entering or nesting in unwanted areas, such as attics, chimneys, or walls. This exclusion door allows squirrels to exit a structure without being able to return, providing a humane way to deal with squirrel infestations.
