I have posted this before, but now that it is gardening season I will re-post.
Herbal Deer Repellant
1 cup water
4 drops rosemary essential oil
wisk all ingredients together very well & pour
through a wire mesh strainer.
Put in a spray bottle & spray your plants once a week.
refrigerate any leftovers.
This works very well for me. Hope it helps your critter problems.
