If you use citronella outdoors, follow the product label and avoid creating concentrated chemical mixtures of your own.
8. Vinegar
The sharp smell of vinegar makes it another common household suggestion.
Some people place vinegar in containers around outdoor areas or use diluted vinegar on certain surfaces.
However, vinegar is not a dependable method for controlling snakes.
It can also damage plants, soil, stone, wood finishes, and other surfaces depending on how it is applied.
If you use vinegar at all, avoid indiscriminate spraying and never assume that a vinegar-treated yard is protected from snakes.
The most useful role for vinegar is often simply that it is inexpensive and readily available—not that it has been proven to create a reliable snake barrier.
