Seeing snails around your house, garden, or aquarium might not be the most pleasant experience. If left unchecked, they will munch on your plants, leave slimy trails around, and could even infest your aquarium. The good news is, there are effective ways to eliminate these pests and protect your property. Whether you prefer a natural solution or are willing to use pesticides, you can rid yourself of these troublesome snails.
Steps
Eliminate Land Snails
Create a Beer Trap to Catch Snails. Pour some beer into a small container, such as a can or similar item. Bury this beer trap in your garden or near areas where snails are likely to gather, ensuring the opening of the trap is about 2.5 cm above the ground. The beer's smell will attract the snails, causing them to fall in and drown.
- Adding a little yeast can make the trap more enticing to snails.
- You might need to set up multiple traps, as each one will only be effective for the snails nearby.
- You can also use plastic cups, yogurt containers, bowls, or baking molds as traps for the snails.
- Do not bury the beer trap level with the ground, as beneficial creatures may fall into it and perish.
Catch Snails if You Have the Time. Snails are most active in the early morning and late at night, making these the ideal times to catch them. Simply collect the snails and place them into a bucket or container to relocate them elsewhere.
- You can also choose to kill the snails you catch.
- To catch snails more quickly, you can place an overturned bowl or plant pot in the garden, near areas where you often see snails. The snails will usually crawl under the pot, making them easier to find.
Spray Cold Coffee to Kill Snails. The caffeine in coffee has a harmful effect on snails, and they will die if sprayed directly with coffee. Be sure to thoroughly wet the snails with the coffee to ensure they are killed.
- Brew a pot of coffee and allow it to cool, then pour the coffee into a spray bottle for use indoors or in the garden.
Spray Garlic Water to Repel and Potentially Kill Snails. Spray garlic water around your house and garden when needed. If you spot a snail, you can spray it directly with the garlic water. This solution can kill a few snails and repel others.
- Make garlic water by soaking 3 crushed garlic cloves in 1 tablespoon (15 ml) of vegetable oil overnight, then mix with 1 liter of water, strain out the solids, and pour the liquid into a spray bottle. Add 1 teaspoon (5 ml) of liquid soap and shake before use.
Use Iron Phosphate Bait to Kill Snails. Iron phosphate is a molluscicide, meaning it can kill snails and slugs. Simply place the bait in your garden or areas where snails are frequently found, and they will be drawn to it and consume it. After ingesting the iron phosphate, the snails will die.
- You can find iron phosphate bait at gardening stores or purchase it online.
- This bait will stop snails from eating, but it may take up to a week for them to die.
- Iron phosphate is the safest type of bait, as it is non-toxic to humans and pets.
Use a Molluscicide Containing Ferric Sodium EDTA to Quickly Kill Snails. Apply this product in the late afternoon or early evening, when the snails are beginning their nighttime activity, so the treatment is fresh. Sprinkle a thin layer of the product around areas where snails are commonly found. They will be attracted by the bait in the mixture, and after consuming it, the snails will die within 3 days.
- This product is safe for use in the garden, but keep it out of reach of children and pets.
- Only apply a thin layer to kill snails. Avoid piling the product, as other animals might ingest it and become ill or die.
Chickens love eating snails, so having a chicken roam freely in your garden can be a great natural solution for controlling snails. The chicken will hunt down and eat the snails, so you won't have to do it yourself.
- Ducks can also eat snails, though they typically prefer shell-less snails.
- Remember to check the regulations in your area to see if keeping chickens in your yard is allowed.
Encourage the presence of natural snail predators in your garden, such as frogs, toads, turtles, birds, and snakes. The choice of species depends on your local environment, so it's advisable to consult with the local agricultural and rural development office or a gardening club for effective biological control options in your area. They can recommend plants and shrubs to grow and ways to create a natural habitat, such as a rock garden.
- You can also search online for the best methods to attract natural predators in your region.
Create an environment that's unfavorable for snails.
Water your garden in the morning to prevent snails from laying eggs. Snails need moist soil to lay their eggs, and they typically do this at night. By watering your garden in the morning, the soil will have time to dry before evening, making it less conducive for egg-laying.
- If possible, consider using a drip irrigation system or soaker hose to control soil moisture, making it harder for snails to reproduce.
Clean up wet, decaying organic debris in your garden. Snails are attracted to damp, decomposing organic matter, and they'll hang around if you don't remove it. Make it a habit to clean up your yard and garden at least once a week. Dispose of this debris in a trash bin or compost pile.
- Don't forget that a compost pile can also become a gathering spot for snails. Keep compost materials away from your garden, and consider using rough, abrasive materials around your garden to prevent snails from entering.
Surround your house or garden with rough, abrasive materials to repel snails. Some effective options include crushed eggshells, diatomaceous earth, gravel, wood ash, and cedar wood shavings. These materials form a barrier that's difficult for snails to cross. You can spread a thin layer around the area you want to protect from snails.
- Crushed eggshells are an easily accessible material to deter snails inside your home.
- Diatomaceous earth, gravel, wood ash, and cedar wood shavings can be purchased at gardening stores or online.
Sprinkle coffee grounds around your garden because caffeine can help keep snails at bay. Snails are sensitive to caffeine, so they'll instinctively avoid coffee grounds. You can spread the grounds on the soil or around your home's perimeter as needed.
- If you don't drink coffee, visit a local café to ask for used coffee grounds.
Use copper wire or copper tape to keep snails away. Copper causes a mild shock to snails, which makes them avoid it. You can wrap copper tape around potted plants, garden beds, or any area frequented by snails. If you're using copper wire, you can tie it around plant pots or stakes to protect your plants.
- Another option is to place a few copper coins around the area you want to protect.
- Copper tape can be found online or at gardening stores.
Plant species that snails dislike. These include foxglove, castor bean, Japanese anemone, daylilies, succulents, sage, and fennel. Each of these plants has a scent that snails find unpleasant or a texture they avoid touching. By planting these in your garden, you'll reduce the likelihood of snails visiting.
- For example, you can place a pot of these plants near areas where snails are common inside your home.
- Note that foxglove is toxic, so it might not be suitable for households with children and pets.
Prevent snails in your aquarium.
Quarantine your aquatic plants for two weeks before adding them to your aquarium. Aquatic plants are the most common source of unwanted snails. Snail eggs and larvae often cling to the plants and will proliferate once introduced to the tank. Fortunately, you can avoid this by isolating your plants for two weeks before introducing them into your aquarium.
- If you notice any snails during the quarantine, remove them immediately.
Treat your plants with a bleach and water solution, mixed at a ratio of 1:19, before adding them to your aquarium. Prepare the solution by combining 1 part bleach with 19 parts water. Dip each plant into the solution briefly, then remove it immediately. This will kill any snails or snail eggs still on the plant. Rinse the plants thoroughly in clean water before placing them in the tank.
- One second of dipping per plant is sufficient, so dip and remove them in one swift motion.
Perform a thorough cleaning of your aquarium and gravel. If you have time, you can manually scrub the snails off surfaces. Transfer the fish to a temporary tank and then drain all the water from your main aquarium. Remove everything from the tank, including gravel and substrate, then scrub the tank walls to remove any snails.
- For the best results, replace the gravel and substrate.
- Rinse plants and other decorations before putting them back in the tank. You can soak them in a bleach solution (1 part bleach to 19 parts water), which will eliminate any snails or eggs.
- If you don't want to remove everything from the tank, you can use a siphon to remove only the gravel and substrate, but you'll still need to remove the snails from the tank walls.
Introduce snail-eating fish to your tank. Certain fish species are natural predators of snails and can help keep your tank clean. When selecting fish for snail control, be sure to check that the species you're considering doesn't prey on other fish in your tank. Also, make sure the fish isn't too large for your aquarium.
- For smaller tanks, you might consider zebra fish or kuhli loaches.
- For larger aquariums, consider American flag fish, pictus catfish, koi, or large goldfish.
- Alternatively, you could add a single assassin snail to your tank. It will consume other snails and won't reproduce in large numbers.
Place a snail trap in your aquarium to catch and remove snails. The trap will attract snails into it but prevent them from escaping, allowing you to easily remove them without harming your fish.
- Snail traps are available at pet stores or online.
- You can also create your own trap by attaching a lettuce leaf to the tank wall. Leave it overnight and remove the lettuce the next morning. The snails will have gathered on the leaf, and you can now remove them from your aquarium!
Add copper sulfate to your aquarium to control snails without harming the fish. Snails are sensitive to copper, and they will die if copper sulfate is present in the water. Copper sulfate is safe for most fish species, making it a reliable option for most aquariums.
- If you're concerned about your fish, check whether the species you're keeping is sensitive to copper.
- Do not use this method if your tank contains shrimp or ornamental snails, as they are also sensitive to copper.
- Copper sulfate can be purchased online or at pet stores.
Advice
- If you're too busy to deal with invasive garden snails, you can hire a pest control service. They offer snail eradication services and can help remove snails from your garden.
- Sometimes, the presence of pests indicates that your plants are not healthy. Taking proper care of your plants can help prevent pests from becoming a problem in the first place.
Warning
- Avoid using salt to kill snails, as it can damage plants and soil in your garden or yard.
- Be cautious when using coffee grounds, as they can affect the pH of your soil.
