In fact, most of the snake repellents on the market don't really work.
Not even realgar.
Most of the realgar you can buy now isn't the real stuff that can repel snakes; its effect is far inferior.
Other methods like snake repellent powder, sulfur, and plant ash are also quite limited in their effectiveness.
Because snakes are not as afraid of chemical smells as they are of high temperatures.
Many times, clearing the surrounding grass and lighting a bonfire can avoid most venomous snakes.
If there's a snake-repellent device that emits continuous vibrations, that could be used too.
Snakes are also very sensitive to vibrations.
Finally, handling kitchen waste properly, by throwing trash as far away from the camp as possible, helps.
This way, the trash won't attract small mammals like mice to the camp, and without food, snakes naturally won't come.
Of course, this excludes setting up camp right at the entrance of a snake's den.
