How to Control Slugs Organically

Slugs are one of the most common pests in gardens, and they can wreak havoc on your plants. If you’re looking for ways to control these slimy pests without using chemicals, you’re in luck.

Create a Barrier

The best way to control slugs is to create a barrier that they can’t cross. There are a few different ways to do this.

Diatomaceous Earth

One option is to lay down a layer of diatomaceous earth around your plants. This powder will cut through the slug’s soft body, causing it to dehydrate and die. You’ll need to reapply diatomaceous earth after rain or watering, but it’s otherwise a low-maintenance option.

Slug Trench

Another option is to make a slug trench. To do this, dig a shallow trench around the perimeter of your garden bed and fill it with beer. The yeast in the beer will attract the slugs, and they’ll fall into the trench and drown.

You’ll need to check the trench regularly and replenish the beer as needed.

Organic Slug Bait

A third option is to use organic slug bait. This bait uses iron phosphate, which is lethal to slugs but safe for humans, pets, and wildlife. You can find organic slug bait at most garden stores. Simply apply it around your plants according to the package directions, and the slugs will be controlled within a few days.


There are a number of ways to control slugs organically. By creating a barrier or using organic slug bait, you can effectively control these pests without resorting to chemicals.

Whichever method you choose, be sure to take action early. The sooner you start controlling slugs, the better off your garden will be.
