Formulated for professional use, Goose Scram is a safe yet effective repellant that trains geese and coots to stay away from protected areas and deters their return. It's made with a blend of nontoxic, organic ingredients that encourages the birds to find another place to frequent, graze and nest in. Great for use around reservoirs and swimming areas where fecal matter can carry bacteria, along with public area where birds can get aggressive during nesting season. Sprinkle liberally at a rate of 1 lb. per 350 square feet where bird activity has been observed. Each application should last approximately 25 days; re-application may be required after periods of extremely heavy rain.
