Does Garlic Help Against Snails & Slugs? | Field Test

Can garlic repel and deter slugs and snails?

Garlic is supposed to help against almost everything—for example against ticks, moles, voles, and now also against snails.

Here is a test that shows how slugs and snails react to garlic.

Slugs and snails dislike eating plants of the Allium genus.

Why should garlic work?

Snails and slugs do not eat garlic.

Leeks, chives, wild garlic and ornamental garlic are also only part of a slugs diet when they are sick or weak.

These plants therefore have means to deter slugs and snails.

How should garlic be used?

One idea is to transfer the protection of garlic to other plants.

To do this, you should make a garlic decoction and then spray it on endangered plants.

But does that help? How strong is the protection really?

Garlic against slugs & snails: Test

I cut garlic into thin slices and laid them out in a semicircle.

Then I placed freshly collected snails and slugs in the middle.

The following video shows what happened.

You could really see a deterrent effect right from the start.

The smell alone seems to have repelled most slugs and snails at first.

But then some turn around and just crawl over it.

So, the result was ambiguous.

There was a deterrent effect, but not enough to prevent the snails from crawling over it.

It is doubtful whether garlic as a feeding inhibitor promises success.

Furthermore, it is questionable how long the protection of garlic might last and how quickly it will be washed off when it rains.

It might not be enough to spoil the appetite of slugs when the slugs’ favorite plants are available for selection.
