Garlic: A Powerful Snail Repellent

The use of garlic as a natural pest deterrent is well-established. Snails, like many other pests, are repelled by the strong smells emitted by certain plants, and garlic belongs to the family of alliums, which is renowned for its ability to keep pests at bay. One of the active compounds responsible for garlic’s potent odor is allicin.

Allicin: The Snail-Repelling Compound

Allicin is a sulfur-based compound that is released when garlic is crushed or chopped. This compound not only gives garlic its characteristic smell but also serves as a powerful deterrent for snails and other unwanted garden invaders. When snails encounter the scent of garlic, they perceive it as a threat and tend to avoid areas where the smell is present.

Alliums: A Family of Pest Deterring Plants

Garlic is not the only allium that has repellent properties. Other members of the allium family, such as onions and leeks, also possess pest-deterring abilities. However, while these plants can help to some extent in keeping snails away, they may not be as effective as garlic due to their milder fragrances.

The Ineffectiveness of Ornamental Alliums

It is worth noting that ornamental alliums, which are grown primarily for their attractive flowers rather than their scent or culinary use, are unlikely to deter snails. These varieties often have a weaker fragrance, making them less effective in repelling pests.

How to Utilize Garlic to Repel Snails

If you are eager to protect your plants from snail invasions, here are several effective methods to use garlic as a natural snail repellent:

1. Garlic Spray

Creating a garlic spray is a simple yet effective way to deter snails. To make the spray, you’ll need two bulbs of garlic (not individual cloves) and one liter of water. Crush the garlic or use a blender to mix it with the water. Transfer the mixture into a spray bottle and apply it directly to the plants. The garlic spray not only keeps snails at bay but also makes your plants unappetizing to them.

2. Crushed Garlic Cloves

For a more direct approach, simply crush or chop garlic cloves into small pieces and sprinkle them on top of the soil in your garden. The pungent odor of garlic will discourage snails from venturing near your plants.

3. Garlic Salt

Garlic salt combines the pungent smell of garlic with the added deterrent of salt. If you’re facing a severe snail infestation, this method can be more aggressive in repelling the pests. Sprinkle the garlic salt around your plant pots and flower beds, but exercise caution, as excessive salt can harm your plants.

4. Interplanting Garlic

If you have a taste for growing garlic, take advantage of its snail-repelling properties by interplanting it among other susceptible plants. The presence of garlic will serve as a natural barrier, keeping snails away from your cherished flowers and vegetables.

Garlic: Safe and Beneficial for Your Plants

One of the significant advantages of using garlic as a snail repellent is that it is safe for your plants. Unlike some chemical pesticides, garlic poses no harm to your greenery when used correctly. In fact, garlic offers several benefits to your plants, making it an even more attractive choice for gardeners.

Root Stimulant

Garlic acts as a natural root stimulant, encouraging the roots of your plants to absorb more water and nutrients. This boost in nutrient uptake results in healthier and more vigorous plant growth. Young plants, in particular, benefit greatly from this root-stimulating effect.

Versatile Pest Deterrent

Not only does garlic deter snails, but it also works against other common garden pests such as slugs and aphids. This versatile characteristic makes garlic an excellent all-around pest deterrent, promoting overall garden health.


In conclusion, garlic is indeed a potent and effective method for deterring snails from your garden. The presence of allicin in garlic creates a powerful scent that repels snails and other pests, making it a valuable addition to your gardening arsenal. Whether you choose to make a garlic spray, use crushed cloves, sprinkle garlic salt, or interplant garlic, these methods will help safeguard your plants from snail invasions.

Moreover, using garlic as a natural repellent ensures that your plants remain safe and healthy, thanks to its root-stimulating properties and all-around effectiveness against various pests. So, why resort to harmful chemicals when you can harness the power of garlic to create a thriving and snail-free garden?
