The sounds of fall include the honks and quacks of migrating geese and ducks. These water fowl need to rest and feed during their flight South. If their pit stop happens to be your backyard garden, you might try BirdStop, a repellent developed as a general bird repellent for commercial orchards in the late 1980s by Leonard Askhams, professor of vertebrate pest management at Washington State University. It works on birds that feed on vegetation and is especially effective at repelling geese and ducks.

BirdStop's active ingredient is methyl anthranilate, a bitter-tasting and foul-smelling compound extracted from Concord grapes. After tasting or smelling the repellent, geese and ducks and most birds quickly move on. The concentrate is diluted with water, and 1 gallon covers an acre. BirdStop breaks down under exposure to ultraviolet light, so you have to reapply it after mowing (or every 2 weeks) on lawns and weekly on food crops. One gallon of concentrate costs about $113.
