Snakes are reptiles found virtually in all parts of the earth – the forest, desert, water and most commonly anywhere rodents, their prey habitat. The way they unhinge their jaws to feed and their tendency to bite inspires fear and disgust in a lot of people. Some snakes are venomous and are capable of biting victims to death instantly. 

Nonetheless, the fear of snakes over the years has been exaggerated even though snakes are harmless.

Recently, a WhatsApp user, Michael Afolayan, circulated a write-up claiming that salt can repel snakes and can also be used to prevent fire in the kitchen.

The write-up which has gone viral also claims that the rainy season is a season for snakes to come out of their hibernation to a cooler environment occupied, thereby increasing the chances of contact with humans.


Dubawa found research by a pet company, Insect Cop in the United States titled “salt against snakes.” The research revealed that using salt to repel snakes is a rumour that originated from an old wife’s tale that was not researched. According to Insect Cop, the tale is dated to pre-goggle era where such methods are only based on a general knowledge that most animals will probably turn tail if you fling a handful of rock salt into their faces.

Another research by Oddly Cute Pets Company also in the United States, notes that the old wives’ myth was generated from the fact that salt affects slugs and snails to the point of death. The research concluded that salt does not repel snakes and it won’t go out of its way to avoid salt.

Further Google search led to an article by Tibs Bulletin claiming that a 50-50 mix of salt and crushed garlic or garlic and onion crushed together can serve as a snake repellant if sprinkled around the edge of a property as the strong smell of the combination can irritate snakes.

Expert opinion

A consultant veterinarian with the Kwara State Veterinary Service, Dr. Bukky Richard, said snakes can only be affected if kept in a salt solution for a long time.

Dubawa met with an animal keeper with the University of Ilorin the zoo, Kareem Yusuf, who shared his experience in the care of snakes. He explained that snakes don’t like hot temperatures and they come out more in the hot season and not in the cold or rainy season.

“Snakes don’t lick or slurp their food, they bite, strangulate and swallow,” he says. He added, “you may make the snake blind by pouring salt into its eyes but you can’t keep them away just by pouring salt in your water closet or boundaries of your home”. He also agrees that soaking a snake in a strong concentration of salt is acidic and can kill any animal including snakes.

On whether it can be used to extinguish fire in the kitchen, a Kwara State fire expert and former director of the Kwara State Fire Service, Waheed Yakub, says this is not true, adding that salt is a make up of sodium chloride which is not a chemical that can quench fire in the kitchen or anywhere else. “You can only quench fire in the kitchen by smouldering, popularly called “cover up” and not by using salt,” he said.


It is not true that salt can repel snakes since it is not a slug but if mixed with garlic it can irritate the snake to slide away but not kill it. It is also not true that salt can extinguish domestic fire outbreaks at home.

The researcher produced this fact-check per the Dubawa 2021 Kwame KariKari Fellowship partnership with The Nigerian Television Authority to facilitate the ethos of “truth” in journalism and enhance media literacy in the country.
