Answer: Many gardeners use the repellant sprays with varying success, but they must be applied and reapplied according to the instructions in order to be as effective as possible. There are also many home remedies such as using soap, blood meal, human hair and so on, but in my experience the only truly reliable solution is a fence.
Deerbusters (http://www.deerbusters.com/) offers a fence and solar battery along with several different options.
Hope you outwit those rascals!
