To combat slugs in your garden, try these methods:
Handpicking: Regularly check your garden in the evening or early morning and pick off slugs by hand. Dispose of them far from your plants.
Beer traps: Bury a shallow dish in the ground and fill it with beer. Slugs are attracted to the beer and will crawl in and drown.
Copper barriers: Copper tape or copper wire around your plant pots or garden beds can act as a deterrent, as slugs dislike crossing copper.
Diatomaceous earth: Sprinkle diatomaceous earth around plants. It’s abrasive and dehydrates slugs when they come into contact with it.
