1. Create a barrier: Slugs and snails are attracted to moisture and damp soil. To deter them, create a barrier around your plants using copper tape, gravel, or diatomaceous earth. Copper tape is a good option because it’s inexpensive and readily available. Copper tape is a thin, flexible material that releases copper ions into the soil, which slugs and snails find toxic. Gravel and diatomaceous earth are also effective barriers, but they can be more expensive and require more maintenance. 2.

Aluminum Foil Aluminum foil is another effective deterrent for slugs and snails. The reason behind its effectiveness is that it reflects light, which confuses the slugs and snails, making them unable to navigate their way around. 5. Diatomaceous Earth Diatomaceous earth is a natural powder made from fossilized algae. It is a highly effective and safe alternative to chemical pesticides. It works by dehydrating slugs and snails, causing them to die. 6. Boiling Water Boiling water is a simple and effective method for killing slugs and snails.
