I like Irish Spring soap but Dial works well too. If you' re just protecting a few trees hanging deodorant soap from a branch at deer nose level has worked 100% for me. The bars last about a year before they need replacement. Other people spray soap solution on the trees for the same effect.

If you' re trying to keep deer out of a large area go to a company called" Forestry Supplies" . They sell deer repellant that can be sprayed over larger areas.
