The Away With Geese Residential Unit keeps geese off of grass lawns, yards, fields and gardens. It features an amber 360-degree solar-powered LED light that flashes every two seconds in a 100-yard radius, from dusk to dawn, year-round. The light is disturbs the very sensitive eye-sight of the geese at night, causing them to relocate to a different habitat. *The flashing lights target the geese’s sensitive eyesight and create an environment they find uncomfortable. Since geese prefer to stay in the same location both day and night, they quickly relocate to a more suitable habitat. This proven, effective solution scares geese away and keeps them away for good.

We ask that our customers try our product for at least 3 months. *While it is annoying to the geese, it is dim to people and not a problem in a residential setting. *The light mounts on a durable cylindrical base comprised of ¼-inch thick ABS black plastic that never fades, cracks, or needs to be replaced. *This base mounts on the ABS black plastic ‘fin’ which encases a ¼ inch galvanized steel metal spike. *The fin/spike holds the unit securely into the ground, with the bottom 6 inches penetrating the ground and top 4 inches integrated into the fin, which holds the base. *The design allows for effortless installation—just put the fin/spike into the ground and place the base on top, and then feel free to move around when desired. *When installed the unit is 18 inches in height, right at the eye level of the geese.
