Slugs and snails in the garden can be extremely frustrating, as these pests feel unpleasant to touch and destroy plants in remarkably short order. Fortunately, there are a number of natural techniques which can be used to get rid of slugs. There's no need to resort to slug bait and poisons, which can potentially hurt animals in your garden along with the slugs.
One very effective technique is to create borders around your plants which slugs will not cross. Strips of copper can be very effective to get rid of slugs, as slugs and snails do not like crossing this metal. You can also surround plants with crushed shells, diatomaceous earth, cinders, and lava rocks. These surfaces hurt the slugs when they try to cross them, acting as an excellent deterrent.
It is also a good idea to get rid of decaying organic material, as slugs are attracted to it. Unfortunately, this also requires getting rid of mulch, so if you have plants which must be mulched, surround them with a border as above to make the mulch less appealing.
Hand picking is also a solution for getting rid of these garden pests, and if you're feeling squeamish, you may be able to find a young person in the neighborhood to do it for you, for a small sum. As you hand pick, drop the slugs into salted water to kill them. To make the process even easier, set out overturned flowerpots overnight to attract the slugs, and then drop the flowerpots into salted water to get rid of your unwanted guests.
Another technique to get rid of slugs involves setting out traps with natural bait. Slugs are very attracted to the odor compounds emitted during the process of fermentation, so you can fill shallow saucers with beer to attract slugs. When the slugs enter the pans, they will drown, and you can periodically empty the beer traps to remove them.
You can also get rid of slugs by encouraging avian friends in the garden, as many birds love slugs. Set up bird feeders to welcome birds of all sizes, or buy some ducks or chickens. Domesticated fowl can help get rid of slugs while also brightening the garden and assisting with the weeding, although you may want to shelter delicate plants from clumsy feet with netting. Small chickens like Bantams are ideal for this task, and these friendly birds can also make the garden a more cheerful place to be.
