The Liquid Fence Goose Repellent 2.5 Gallon is an effective solution to keep geese and other large birds off turf, lawns, and recreational areas. Its active ingredient, methyl anthranilate, is a food-grade grape extract that creates an unpleasant taste and smell for geese while remaining non-toxic to humans, pets, and plants. The liquid concentrate is easy to apply with standard spray equipment, rainfast once dry, and works on a variety of surfaces including golf courses, sports fields, and waterfront properties.
