7. This works surprisingly well

Enough non fat dry milk to make a 1 cup per the directions on the box to a gallon of water. Add teaspoon of castile soap which acts as a wetting agent. Spray liberally (you wouldn't be a conservative on DU, now would you?) on your plants. pour out left over around the base of the plants and rinse your sprayer well. Do not keep any as it will sour.

You may have to do this once a week. The milk will sour but we can't smell it but they can, and find it disgusting.

I've heard of using Irish Spring soap bars as a deterrent. The problem is expense and rain will diminish the bars quickly.
