6. Onion

Much like its close relative garlic, onion is another kitchen staple
that can serve as a natural deterrent for snakes. Its sharp and penetrating odor
is thought to be offensive to snakes, thereby reducing the likelihood of them
entering your garden.
Planting onions along garden borders or within plant beds offers a simple,
yet effective way to potentially keep these reptiles away.
As a bonus, onions are easy to grow and harvest, providing you with a fresh supply
for your culinary needs while enhancing the protective qualities of your garden.
