Squirrel Control
Prevention is key to keeping gray squirrels, or any other animal, from taking up residence in your home or building. Keep trees and overhanging branches away from your structure. Make sure all parts of the exterior of your building are maintained, and repair any rotted or damaged areas of eaves and soffits. If squirrels do get into your home, a thorough inspection of how they are entering and exiting, followed by a structure trapping and exclusion protocol are necessary.
