How to Get Rid of Slugs in a Garden

Updated February 21, 2017

Garden slugs love damp, moist, places in your garden. They especially like to hide under bark that you have used as mulch and enjoy eating your plants at night. These snails without the shell leave a slimy trail on your patio or deck. Getting rid of them is easy--they love beer. Slug traps are easy to make and very effective.

Determine how many slug traps you will need. They should be spaced about a foot apart from each other and in the area that you have seen slugs.

Level the soil in the spots that you are going to place the traps. You can use a small hand cultivator tool to do this if the soil is compact or just your hand if the soil is loose.

Place the slug traps (empty tuna cans) in the soil and fill them 3/4 of the way full with beer. Do this towards evening so that the beer will not evaporate.

Check your slug traps in the morning. You should have several slugs in each trap.

Dispose of the dead slugs. If you think that there still may be some slugs in your garden you can follow the same procedure again until there are no further sign of slugs.


Empty tuna or cat food cans should be used for the slug traps They make great traps because they are low making it easy for the slug to crawl into and they won't tumble over when a slug climbs on them. However, you could even use a small paper cup although they ten to tip over.
