How Often Should You Make a New Batch?

Why This Works

Deer have a strong sense of smell — and this mix of garlic, vinegar, soap, and cayenne offends all their senses. The cayenne especially deters nibbling by making your plants too spicy to stomach.

Bonus Tips: Focus on new growth — deer love tender shoots. Don’t forget to spray at deer height, not just the base of the plant. Also helps deter rabbits, squirrels, and curious raccoons.
