You can take some crushed pieces of garlic and put them on top of the soil. Then, any slug which passes your garden will be sure to avoid the soil.

Garlic Salt 

We all know that slugs and salt do not go together. So, to make garlic more effective, you can use garlic salt. The method is simple: You only need to sprinkle some garlic salt around your plants, so any slug which attempts to climb, encounters the salt.

In the process, the salt will dry the slug, causing it to die. 

Garlic Powder

A common kitchen ingredient we all know about is garlic powder. In addition to adding flavour to our food, garlic powder also makes an excellent slug deterrent.

You can sprinkle some of the powder on the soil and the plants and their leaves. Garlic contains allicin which is known to tackle slugs.

Growing garlic plants is an effective way to deal with your slug problem. Not only can you use the garlic plant, but you will also be keeping the slugs away.

It is important to protect the more vulnerable plants in your garden. To provide these plants protection, you can interplant strong plants like garlic that keep pests away.
