Dot Pattern Solutions

These dot pattern solutions meet the recognized 2×4 Rule as established in many municipal regulations and guidelines. The 2 x 4 Rule refers to research by the American Bird Conservancy and others that have shown that horizontal lines must be spaced two or fewer inches apart and vertical lines must be spaced four or fewer inches apart to deter the majority of birds. The difference presumably has to do with the shape of a flying bird.
