If you are looking for something very inexpensive to get rid of the geese, you can try Bird Repellent Ribbon. If you live in a windy area this ribbon may blow away. One way to stop this from happening is to place weights on the stands that come with the ribbon.

Also be sure to notify the lawn care people that you have ribbon on the ground so they do not run over it. It can be bought for less than $10 in small quantities. It works because the geese are afraid of the shiny reflections of the ribbon. You can make your own stakes and apply a small strip to the top to save on the ribbon. That way you only need to replace small quantities and lawn care will be easier.
