Q. What do I use for deer repellants?
You can try the soap, but I suspect that Hinder would be more effective. The soap was something we used years ago before the liquid repellants were developed. The soaps that we used were the very strong smelling ones like Dial or Lifebuoy. Netting works, except for the little branches that poke through the net.
Effective protection from deer is one tough problem. You may want to consider a 5 foot fence, which, from what I’ve been reading, may work. See the link below on effective deer fencing. See also the subject guide on Deer in the Garden.
