There are numerous claims that snakes possess an incredibly advanced sense of smell, although it is nothing like what we humans have. Instead of simply smelling using their nostrils, they rely on a unique organ referred to as the Jacobson’s organ. It is a sensory apparatus designed specifically for the purpose of detecting particles of chemicals through the tongue. As a result, the flicking of a snake’s tongue can be perceived as the process of tasting the surrounding air in order to analyze the environment.
Given how responsive they are to such chemical signals, it would make sense to think that an extremely strong and foul odor would drive them away. It does seem logical since the smell will either overwhelm them or be nauseating, which means that the snake will not want to linger in the area. However, it is not as straightforward as it sounds. Although a particular smell may cause discomfort in the animal and deter it from staying in the area for prolonged periods, there are no definitive studies on a particular smell that could repel the snake.
It is also important that you consider the factors that influence the behavior of snakes before buying a number of products such as oils or powders. Generally speaking, snakes visit areas that provide them with the “triple big,” including food, shelter, and suitable weather conditions. If your property provides abundant sources of insects and rodents, along with suitable shelters, it is likely that the snake will remain there, even if the area doesn’t smell right.
This is the reason why the actual “secret” to preventing snakes involves more physical work than using any magic smell. Mowing the grass, removing heaps of firewood, sealing cracks, and ensuring that you do not have mice are far better approaches compared to using a repellent. Furthermore, if you have venomous species of snakes, then you definitely need to contact an expert, not experiment with DIY solutions.
Clove and cinnamon oil, for example, may be suggested as natural snake repellents. Both these oils have extremely high concentrations of highly irritating substances that will most certainly annoy a snake’s sensory receptors. Some individuals dilute the oil and apply it near doors and entryways to form a minor barrier.
The fact is that these oils are very concentrated. Extreme caution should be exercised when using them since they may irritate your skin and even your eyes. Moreover, they may be harmful to your pets and household animals; therefore, you shouldn’t apply them undiluted.
The sulfur method
This is another type of traditional remedy which has been used since ages. The principle behind using sulfur is that snakes avoid areas where the environment is very foul due to the stench emitted by this substance.
It can be applied to the edges of your property or around the deck area. But honestly, it has its downsides. For one, it smells terrible to humans, too. It can also mess with your soil quality over time and isn’t great for your plants or certain building materials. It’s a bit of a “cure is as bad as the disease” situation for many homeowners.
White vinegar
White vinegar is one of the common solutions used in areas where moisture is present, such as the edges of ponds, poolside decks, or damp crawl spaces. It is highly acidic, and its strong smell is thought to interfere with a snake’s ability to “taste” the air properly.
It may work in situations that require a quick, targeted response, but white vinegar acts as a non-selective herbicide. It can damage plants and alter the pH balance of your soil, so it’s not something you should use extensively in your garden.
Garlic and onions
Next come garlic and onions. These two have their pungent sulfur smell, particularly once they’re diced up or minced, that supposedly drives snakes crazy.
People will leave these out near entrances, or make their own “smell sprays,” but here’s the rub: Once that stuff starts to decompose, it attracts all sorts of critters, including insects and vermin—animals that snakes prey upon. Plus, onions and garlic are actually dangerous for dogs and cats to eat. And again, the science on whether a snake actually cares about the smell of your kitchen scraps is pretty thin.
Citrus, lemongrass, and citronella
Citrus and other plants such as lemongrass and citronella are some of the most popular organic pesticides out there. These are the plants with strong fragrances that we usually love, yet bugs, and according to some snakes too, don’t.
Lemongrass stands out since it works against insects. The fewer insects you have, the fewer foods snakes will come for in your garden. In terms of citrus, you can use either dried or diluted fruit oils on patios. However, since they degrade very quickly, they need to be frequently reapplied, especially right after rainy days.
Cedar oil and cedar mulch
Cedar is yet another major player. Cedar has its natural oils, which produce the distinct “closet” odor, said to be particularly unpleasant for reptiles. Adding cedar mulch to your landscaping will also prove helpful since it helps maintain a dry environment that won’t attract insects.
This choice seems attractive, practical, and decorative; however, it is not an ultimate solution. One more aspect to consider is that it may drive away beneficial insects as well
