The first thing you can do is switch your watering schedule. Slugs go out at night, and they work best in damp conditions. So if you’re watering in the evening, then you’re creating a perfect environment for slugs. Water in the morning so there’s time for things to dry up.
You could try introducing slug predators to your yard or garden if you really want to deal with the slug problem. Frogs are usually the predator of choice. Of course, you’ll need to provide an environment for the frog to survive, and it also means you’ll have frogs in your yard, so be aware of that trade off.
Slugs like some plants more than others. What you can do is plant a distracter plant so that the slugs stay away from your fruits and veggies and other prized plants. Chamomile is a great example. Plant it near your other plants, and the slugs will eat this instead of the others.
You could also use plants that deter slugs instead of distracting them. For example, fennel and rosemary are highly disliked by slugs. Plant them in your garden, and that should help get rid of the little pests.
Diatomaceous earth is one of the best solutions for lots of insect problems in the garden. The product shreds up the slugs’ underbellies, dehydrating and killing them. Sprinkle this around the edges of the garden and near the bases of the plants.
Lava rocks are another product for your garden that are a natural way to kill slugs. Their rough and scratchy surface also rips up the slugs. It will kill them and also, once they learn, they’ll avoid your garden. Just make sure there aren’t any leaves or dirt on the rocks that will cover the surface.
Break up some egg shells and sprinkle them around your soil. Like the previous ideas, this creates a rough surface that cuts up the slugs’ bellies. However, it also helps add nutrients to the soil as the shells break down, so it’s a win-win.
I bet you didn’t know that seaweed is a great natural slug repellent! Mulch the seaweed around your garden, making sure it doesn’t touch the base of the plants. The seaweed is salty, which slugs hate, and when it dries, it becomes rough and scratchy.
A copper wire can work well to deter slugs. Wrap it around the base of your garden, making sure it’s fully exposed. You can also use a copper mesh to protect your plants. The slugs will avoid crossing over it because they don’t like the copper.
A really drastic solution for getting rid of slugs is the old salt technique. Go out to your garden at night and pour some salt on any slugs you may see. The salt kills them pretty quickly. Just don’t go overboard because you don’t want a bunch of extra salt in your soil.
