Trying to keep geese out of your yard is a really tough thing to do and we are unaware of any method that is 100% effective. Most of the liquid repellents have been taken off the market or are not in production any longer. We would recommend the Bird Barrier Goose Guard. The "injured" decoy gives the impression there is a predator or another animal on the property that will harm them, therefore keeping geese away from the area. Another option our customers have found useful is the ScareCrow Sprinkler Motion Activated Animal Deterrent, which sprays the geese with a stream of water when they walk into off limit areas.
