Extremely sturdy, weather resistant squirrel box that can be mounted in a tree for squirrels to gather nuts in. An easy to open door with optional locking mechanism via screw included. This squirrel / chipmunk house is extremely sturdy using 3/4" wood with a traditional, weather resistant, nut colored stain to match the great outdoors. A 1.5" opening on the right side allows squirrels to enter and exit the squirrel house with ease. Note: Even the largest squirrels only need a 1" opening to enter any hole and they love small entrances as they keep intruders out. This squirrel box is the perfect mechanism to gather organic nuts.
