You don’t need harsh chemicals. Copper tape is a slug’s kryptonite. When they touch it, it gives them a tiny electric shock—like tapping a live wire with a wet finger. Stick it around plant pots or along door thresholds.
Other natural options: diatomaceous earth (the fossilized dust that cuts their bodies), coffee grounds (caffeine is toxic to them), or a ring of crushed eggshells. These act like a medieval moat—sharp, dry, and unpleasant. Slugs will take one look and say, “Nope, I’m out.”

What About Salt?
Yes, salt kills slugs instantly. But it’s brutal and not great for your floors or plants. It also dehydrates the slug painfully. If you use it, do it outside. Inside? It’s like using a flamethrower to kill a fly—effective, but messy and a bit excessive.
