Slugs are a gardener’s worst nightmare. These little pests can wreak havoc on your garden, leaving slimy trails and destroying plants. Slugs can be difficult to control once they infest your garden bed and seem to love moist environments. It’s important to take steps early on so you don’t have a slug problem this season or next year! Luckily there are many natural ways to keep slugs out of your garden without using pesticides or harmful chemicals—here’s how:
Plant Slug-Resistant Plants
Plants that are resistant to slugs and snails can be found at most nurseries. Some common plants you may want to plant include: lavender, rue, thyme, marjoram, oregano, and yarrow. Any fragrant plant is a turn-off for these slimy pests. They also dislike plants that are fuzzy or furry.
Encourage Natural Predators
Slugs are a favorite food for many animals. Frogs love them, as do birds and other insects, like beetles.
One way you can control slugs naturally is by building a “beetle bank” for large areas or a “beetle bump” for smaller areas. The process is the same either way. You can build a beetle bump by burying a shallow container with woody material and water in the ground. You could also carve out a furrow for the same purpose. A colorful collar of flowers, leaves, sticks, native grasses, sledges, and native plants will do the trick around this area will bring the beetles right to you.
Sprinkle Crushed Eggshells
Save your crushed eggshells and scatter them around your garden. This will help to repel slugs and snails from coming back for a second helping from your garden! However, you’ll need a lot of eggshells for large areas, and they must be crushed a bit so that they’re small and sharp. Crush them with your fingers or pulse them for a couple of seconds in the food processor to chop them up.
Try Diatomaceous Earth
Diatomaceous earth has been used to kill slugs. Diatomaceous earth is a powder that is very sharp, and it cuts through the skin of slugs. But diatomaceous earth gets wet and then it doesn’t work. Who has time to put it around the plants again after every rain or dewfall?
Make a Homemade Slug Repellent
Did you know you can make your own homemade slug repellent with common kitchen ingredients?
- Boil vinegar in a saucepan for five minutes and add some hot pepper. Keep the mixture boiling until it’s reduced to one cup of liquid.
- Pour the solution into an old coffee mug or jar, let it cool down, then place these homemade slug repellents on your plants every day during wet weather.
Surround the Area with Copper Strips
You can use a copper strip around the perimeter of your garden to keep slugs away. When they come across the copper, and it reacts with their slime, it shocks them. This way you don’t have to spray or touch slug bait and you only need to use a small amount of copper.
In order to keep slugs out of your raised bed, make a copper collar by stapling or nailing a strip of copper tape around the top edge. This also works for containers. Put the tape just inside the rim on the top of the pot.
Add Crushed Gravel or Sand
Put down a layer of gravel or sand on top of the soil in areas where slugs are more likely to be found. You can make a circle around certain plants, garden beds, or your entire garden area. This will help because slugs cannot cross these barriers.
Set Out Non-Alcoholic Beer
Place pots filled with beer at intervals throughout your garden for an organic way to kill off any lurking slugs. Non-alcoholic beer works best. Slugs are attracted to the yeast and will crawl to it, fall down, drown in it, and die. This can get disgusting really fast, though, so you’ll need to empty the cups or bowls frequently.
In conclusion, it is possible to keep slugs away from your garden. Using the natural methods above, you’ll be saying goodbye to those slimy pests in no time.
