Chapter 4: Ammonia, Mothballs, and Other Popular Remedies
7. Ammonia
Ammonia has a sharp odor and is sometimes recommended online as a snake deterrent. However, there is insufficient evidence that placing ammonia-soaked materials around a yard provides reliable protection.
Ammonia can irritate the eyes, skin, and respiratory system. It should never be poured around a garden or used in a way that exposes people, pets, or wildlife to hazardous fumes.
8. Mothballs
Mothballs contain chemicals intended to control certain fabric pests when used according to their labels. Some people mistakenly assume they will also repel snakes.
Mothballs are not a reliable snake-control method. Using them outdoors for this purpose can expose children, pets, and wildlife to toxic substances. They should only be used for their labeled purpose and according to the manufacturer's instructions.
9. Lemongrass
Lemongrass has a citrus-like aroma and is often grown in home gardens. While it can be an attractive landscaping plant, there is no strong evidence that planting lemongrass creates a dependable barrier against snakes.
10. Citrus peels
Lemon and orange peels release fragrant oils when cut or crushed. Some homeowners scatter the peels around outdoor spaces in the hope of discouraging wildlife.
