Cindy, I would guess that the deer are coming to your yard because they discovered some tasty plants there, more than because of the deer statues. There are various things that can be used to try to repel them, such as the PlantSkydd that Crawgarden mentioned, and another one called "Hinder." Some people have had success using bars of soap hung up near the plants, others recommend using human hair (like from a hair salon). I've tried a lot of different things (living in the north woods as I do) and my only real success has been to use a fence or plants that the deer aren't as partial to. For instance, deer love tulips, but rarely seem to bother daffodils.
Here's a link to a list from Rutgers Univ. with a pretty extensive listing of deer-resistant plants:

Happy gardening!
