The flocks of Canada geese that don't fly south for the winter get larger every year, and one of the main food sources that keep them in the North are lawn grasses. In many urban and suburban areas they are becoming quite a nuisance on lawns and golf courses and in city parks with rivers, ponds or lakes nearby. Perhaps more annoying than the feeding damage they do are the copious and fertile gifts they leave behind.
If not-so-wild fowl are fouling your lawn or garden, here is a low-tech solution developed by the USDA Animal Damage Control Office in Waupun, Wisconsin. They suggest making a lightweight, low-visibility fence from materials available at any farm supply store. Surround the area with thin, 48 fiberglass fence posts, set 15' apart. Fasten either poly-twine electric fence wire or plastic baling twine to the posts 4, 8, 12, 18 and 24 above the ground, using adjustable plastic clips. Keep the line tight enough to avoid visible sagging, and the geese won't climb through it. And, though they could easily fly in, they won't -- exactly why not, no one knows.
