Abstract

Geese and swans are repelled by applying methyl anthranalate or dimethyl anthranalate to their habitats or to pelleted agricultural chemicals lethal to geese or swans. With regard to applying the repellent to habitats, preferably the repellent is encapsulated in a starch-based material that is water tolerant and provides time release of the repellent.
