By definition, Canadian Geese are not classified as pest birds and are afforded protection by federal and state agencies. Nonetheless, Canadian Geese are increasingly becoming the scourge of suburbia as their numbers have grown in the past decade from only a few thousand to hundreds of thousands of these birds.
Canada Geese are large water birds with a long neck, large body, large webbed feet, and a wide, flat bill. They have a black head with white cheeks and chinstrap, black neck, tan breast, and brown back. With a wingspan from 4.2 to 6.1 feet, they can weight up to 14 pounds. The familiar V shaped squadron of honking geese heading south is becoming a rare sight. Country clubs and business parks offer tasty manicured lawns and ponds providing an ideal habitat and effectively modifying their migration cycle. Geese are very opportunistic and easily exploit the new “easy living” conditions found in an urban environment.
The Canada Goose can quickly become a problem to any homeowner, property owner, golf course groundskeeper or park superintendent. Each year the Canada Geese usually migrate north to Canada and the northern USA where it breeds in a variety of habitats.
In Arizona with the nice weather more often times the geese decide to stay and use your property as their breeding site and grazing site. They can soon destroy your lawn, contaminate your pond, make playing golf or make your property downright dangerous to walk on.
Types of Goose Deterrents
Liquid Goose Deterrents use the sense of taste to get rid of the geese. This is made using methyl anthranilate, a grape extract that is sprayed on the lawn to give it a flavor that the geese do not like. This substance irritates the goose’s trigeminal nerves and mucous membranes and causes them to leave the area searching for a better grazing site but needs to be applied often.
Sound, visual and light goose deterrents can be used in tandem with the liquid goose deterrents to keep geese off areas that they are a problem. Sound deterrents and predator calls heard by the geese may cause them to leave the area for a safer spot. Coyote decoys are also effective in scaring geese away. The coyote is a natural predator of geese. They love to go after the eggs and goslings of a mating pair; using the coyote decoys on your lawn will trigger the instinct of fear and the geese will leave for a safer home.
Physical barriers such as overhead grid wire (.96mm) and 4″ mesh net can be extremely effective barriers but are site specific. These grids can be installed above water surface to prevent landing. Fencing made of grid wire provides a discrete barrier to dissuade geese from entering property (especially from water areas) and can be electrified for increased effectiveness.
