Where’s the receipe for the deer spray? ?
deer do not like anything smelly Rosemary oil,garlic oil so mix these oils use 100% essential oils in water and pour or spray in area you do not want them Do not use Cayenne ot hot pepper anything it is cruel to burn them

In my experience deer who are really wanting to get at appealing food will not be kept away by any sprays or repellents.
At best these supposed 'deer deterrents' are only temporary, as their odor will quickly be dissipated in the wind or moisture in the air.
Deer have an extraordinary ability to know where food is and to get at it.
