Since the Little Giant Professional Spray Bottle is not a pressurized spray bottle you can expect the spray range to be from 24-36 inches depending on the setting. This is going to be similar to household windex bottle distance.  Please view our hand pump sprayers that spray longer distances of 10-15 ft depending on the pressure. These are best for treating the exterior perimeter of homes as well as commonly used to treat lawns, landscape beds, bushes, trees, and shrubs (depending on the height).
