Avian Bird Repellent repels birds including pigeons, geese, starlings and grackles without doing them harm. Mild enough not to harm humans or pets, it consists of food grade materials. Use Avian Bird Repellent in such locations such as homes, crops, airports, golf courses and commercial businesses. When spraying on crops, it does not change the taste of the food. This simple to use formulation may be applied by spraying, fogging, or ground and aerial applications. Avian Bird Repellent works as an irritant and discourages birds from gathering.
