Welcome, Leslie. There are a lot of things that will repel deer but nothing is a total success. The urine is one thing, Soap is another. I think it is non-coconut oil based soaps.
I found this and many others by googling soap as deer deterrent. "The best known deer repellent is ordinary bar soap. Hung from strings in trees
or large shrubs, whether wrapped or unwrapped, the scent of the soap is said to keep deer away. Some people even attach soap bars to stakes, placed at 10- to 15-foot intervals along the perimeter of their property or garden area."
I hope this is helpful. Good luck!
