Plotsaver (also known as Deer Stopper)works well as does Hinder and Plant Skydd, all three are recommended bywildlife biologists and are commonly used by gardeners and Fish and Game departments around the country and the U.S.F.W.S. All work for about 30 days without reapplication if it does not rain real hard. An electric fence also works very well, set it up and tie rags on it every few feet, cover the rags with peanut butter to attract the deer to the rags, a few jolts from a good fence to a sensitive nose usually does the trick. Most of the suggestions related to socks, scare crows, moth balls, human hair etc. will work for a few days but are usually ineffective for the long haul. You are also a bit late in attempting to get a repellant working, next year have your repellant in place before the garden has sprouted, it is far easier to teach them not to enter an area before it has something to eat available than after they have developed a taste for your plants.
