As temperatures rise, more homeowners are looking for safe and natural ways to discourage snakes from entering yards, gardens, and garages. While no scent offers guaranteed protection, experts say certain strong odors may temporarily make areas less inviting to snakes by interfering with their highly sensitive chemical detection system.
