Snakes generally rely on their highly sensitive sense of smell—using their tongues to track chemical cues in the air via the Jacobson’s organ—which makes certain potent aromas overwhelming and unpleasant to them.
Here are 7 smells snakes hate and practical ways to use them safely around your property to help deter them:
1. Snake Plants (Sansevieria)
-
Why they hate it: While not a liquid or spray, Snake Plants emit a scent and feature stiff, sharp leaves that snakes find unappealing to slither near or navigate through.
-
How to use it: Plant them in tight clusters or rows around your patio, near entryways, or along the perimeter of your yard to create a natural, low-maintenance living barrier.
2. Garlic and Onions
-
Why they hate it: Both garlic and onions contain strong sulfur compounds that irritate a snake’s olfactory senses.
-
How to use it: Mince fresh garlic and onions and scatter them around dark, damp areas where snakes like to hide (such as woodpiles or crawl spaces). Alternatively, you can mix minced garlic with essential oil and water in a spray bottle to treat vulnerable entry points.
3. Cinnamon Oil and Clove Oil
-
Why they hate it: These heavy, spicy essential oils are intensely concentrated. When a snake inhales or slithers through them, the strong aroma overwhelms their sensory system.
-
How to use it: Mix several drops of cinnamon and clove essential oils with water (add a tiny drop of dish soap to help them blend) in a spray bottle. Spray this mixture directly around foundation cracks, doorways, and garden borders. Note: Reapply after heavy rain.
4. Vinegar
-
Why they hate it: Vinegar is acidic and pungent, making it repulsive to a snake’s sensitive skin and nose.
-
How to use it: Pour white vinegar around the perimeter of your property or into any holes and crevices where snakes might enter. A popular method is to soak strips of old cloth or cotton balls in vinegar and place them in bowls around damp areas or near swimming pools.
5. Sulfur
-
Why they hate it: Powdered sulfur is a classic, highly effective chemical repellent. It releases a pungent odor resembling rotten eggs that snakes strongly avoid.
-
How to use it: Sprinkle powdered sulfur around the boundary of your yard, flower beds, or sheds. Caution: Wear gloves and a mask when applying sulfur, keep it away from children and pets, and check local guidelines, as it can be toxic to certain animals if ingested in large amounts.
6. Lemongrass and Citronella
-
Why they hate it: While humans often find citrus and grassy scents refreshing, snakes find the sharp, zesty oils overpowering and irritating.
-
How to use it: Plant live lemongrass around your outdoor seating areas or garden perimeters. You can also spray lemongrass essential oil mixed with water around the foundation of your home.
7. Ammonia
-
Why they hate it: Ammonia mimics the strong, sharp scent of predator urine and chemical irritants, signaling to a snake that the area is unsafe.
-
How to use it: Soak rags or cotton balls in household ammonia and place them in open containers (like small plastic cups with holes punched in the lid) around dark corners of your garage, shed, or crawl space. Keep these out of reach of pets and children.
Crucial Tips for Effective Snake Control
Scents are best used as temporary deterrents. To keep snakes away permanently, you need to make your yard less attractive to them overall:
-
Eliminate hiding spots: Clear away tall grass, brush piles, stacked firewood, and heavy mulch near your home’s foundation.
-
Control pests: Snakes follow their food source. Keep rodents under control by storing pet food securely and sealing gaps in your home.
-
Manage moisture: Fix leaking outdoor faucets and clear out standing water or damp areas, which attract the frogs and insects snakes love to eat.
