1
Make a beer trap to capture the snails.^{[1]XExpert SourceMelinda Meservy
Plant SpecialistExpert Interview. 18 August 2020.} Pour beer into a small container, such as an old tuna fish can. Bury the container in you garden or near the place where you saw the snails, but leave at least 1 inch (2.5 cm) above the soil. The smell of the beer will attract the snails, which will drown in the container.^{[2]XResearch source}
- Adding yeast will make the traps more enticing to the snails.
- You may need to put out multiple traps, as they will only be effective for snails that are close by.
- Other great options for your beer container include a plastic cup, yogurt cup, bowl, or pie dish.
- Don’t bury your beer trap at soil level, as other beneficial bugs might accidentally die in it.

Pick up and remove the snails if you have the time to do so.^{[3]XExpert SourceMelinda Meservy
Plant SpecialistExpert Interview. 18 August 2020.} Snails are most active in the early morning or at night, so this is the best time to go snail-picking. Put the snails in a bucket or container to move elsewhere.^{[4]XTrustworthy SourceUniversity of California Division of Agriculture and Natural ResourcesExtension program of the University of California system devoted to educating and improving local communitiesGo to source}
- You might also decide to kill the snails.
- To make the process quicker, you can put an overturned pot or bowl in your garden or near the area where you’ve seen the snails. The snails will likely hide under the pot, which makes it easy for you to find them.

3
Spray the snails with cold coffee to kill them. The caffeine in coffee negatively affects snails, so they’ll die if you spray them with coffee. However, you have to drench the snail for it to die, so make sure you spray it a lot.^{[5]XResearch source}
- Make your own coffee spray by brewing a pot of coffee, then letting it cool. Put the coffee in a spray bottle to use around your garden or home.
4
Apply a homemade garlic spray to repel and possibly kill the snails. Spritz the garlic spray around your garden, yard, and home, as needed. If you spot a snail, you can drench it with the garlic spray. It may kill some snails, and it will also deter them away.^{[6]XResearch source}
- To make your garlic spray, soak 3 crushed garlic cloves in 1 tablespoon (15 mL) of vegetable oil overnight. Then, strain the liquid into 1 litre (4.2 c) of water. Pour the mixture into a spray bottle. Add 1 teaspoon (4.9 mL) of liquid soap to the solution, then shake the bottle before using.
5
Use can iron phosphate bait to kill the snails. Iron phosphate is a molluscicide, which means it kills snails and slugs. Simply place the trap in your garden or near the location where you’ve noticed snails, and they’ll be attracted to the bait on it. After they come into contact with the iron phosphate, the snails will die.^{[7]XTrustworthy SourceUniversity of California Division of Agriculture and Natural ResourcesExtension program of the University of California system devoted to educating and improving local communitiesGo to source}
- You an find an iron phosphate bait at a local gardening store or online.
- This bait will make the snails stop eating, but they may take as long as a week to die.
- Iron phosphate is the safest bait to use because it’s non-toxic to humans and pets.
6
Use a molluscicide containing ferric sodium EDTA to kill snails quickly. Distribute the product in the late afternoon or early evening so it will be fresh when the snails become active at night. Sprinkle a light layer of the molluscicide around the area where you've seen the snails. The snails will be attracted to the bait mixed into the molluscicide. After they ingest it, they will die within 3 days.^{[8]XResearch source}
- This product is generally safe for use around your yard, but keep your children and pets away from the area.
- The molluscicide should be in a thin layer. Don't put out clumps, as other animals could eat it and get sick or die.
7
Get a pet chicken that will eat the snails. Chickens enjoy munching on snails, so allowing one to roam around your yard or garden is a great natural solution for snail control. The chicken will find the snails for you, so you don't have to do any of the snail removal yourself.
- Ducks may also eat snails, but they prefer slugs over snails.
- Make sure your local laws and ordinances allow you to have a chicken in your yard.
8
Encourage natural snail predators to live in your garden or yard. These include frogs, toads, turtles, birds, possums, and snakes. Which predator you choose will depend on your environment, so talk to your local agricultural extension office or gardening club for recommendations for biological controls that will work in your area.^{[9]XResearch source} They’ll recommend plants or shrubs to grow, as well as natural habitats you can build, like a rock garden.^{[10]XTrustworthy SourceRoyal Horticultural SocietyLeading gardening charity in the U.K. providing resources for identifying, growing and caring for flowers and other plantsGo to source}

Discouraging Snail Activity

1
Water your soil in the morning to reduce egg laying. Snails need to lay eggs in moist soil. Since they typically lay eggs while they’re active at night, you want the ground to dry out before nightfall. If you water your plants in the morning, the ground should dry out over the course of the day.^{[11]XTrustworthy SourceUniversity of California Division of Agriculture and Natural ResourcesExtension program of the University of California system devoted to educating and improving local communitiesGo to source}
- If you can, opt for a drip irrigation system or a soaker hose, which will help manage the ground moisture so that snails can’t easily procreate.
2
Remove moist, decaying debris from around your yard and garden.^{[12]XExpert SourceMelinda Meservy
Plant SpecialistExpert Interview. 18 August 2020.} Snails are very attracted to moist, decaying organic matter, so they’ll likely stick around if you don’t clean up often. Check your yard and garden for debris at least once a week. Be sure to remove these items and place them in a compost or your trash.^{[13]XTrustworthy SourceUniversity of California Division of Agriculture and Natural ResourcesExtension program of the University of California system devoted to educating and improving local communitiesGo to source}
- Keep in mind that a compost pile is going to be a carnival for your snails. Place it far away from your yard and garden. Additionally, surround it with an abrasive barrier to reduce snail activity.
3
Surround your garden or home with an abrasive barrier to deter snails. Great options include broken eggshells, diatomaceous earth, gravel, wood ash, and cedar chips. All of these items are hard for snails to cross, which effectively keeps them out. Put down a thin layer around the location you want the snails to avoid.^{[14]XTrustworthy SourceUniversity of California Division of Agriculture and Natural ResourcesExtension program of the University of California system devoted to educating and improving local communitiesGo to source}
- Crush up eggshells for an easy, at home option.
- You can find diatomaceous earth, gravel, wood ash, and cedar chips at a local gardening store or online.
4
Sprinkle used coffee grounds around your garden, as caffeine deters snails. Since snails are sensitive to caffeine, they will naturally avoid used coffee grounds. Spread the coffee grounds on top of the soil or around the base of your home, as needed.^{[15]XResearch source}
- If you don’t drink coffee, check with your local coffee shops, as they may give away their used coffee grounds.
5
Use copper wire or tape to discourage snail activity.^{[16]XExpert SourceMelinda Meservy
Plant SpecialistExpert Interview. 18 August 2020.} Copper gives snails a tiny shock, so they will instinctively avoid it. You can apply copper tape around potted plants, around your garden edges, or wherever the snails are going. If you’re using wire, tie it around your pots or make copper garden stakes.^{[17]XResearch source}
- As another option, you can sprinkle pennies around the area, as they contain copper.
- You can find copper tape at a local gardening store or online.
6
Add plants that naturally deter snails. These include foxglove, euphorbias, Japanese anemones, day lilies, succulents, astrantia, salvia, and fennel. Each of these plants has either a smell that snails don’t like or an uncomfortable surface that makes it hard for the snail to climb around it. If you have these in your garden or around your home, snails are less likely to stick around.^{[18]XResearch source}
- For example, you might put a potted plant near the area where snails are crawling on your home.
- Keep in mind that foxglove is toxic, so it may not be a good option if you have children and pets in your home.

Keeping Your Aquarium Snail-Free

Download Article

1
Quarantine plants for 2 weeks before putting them into your aquarium. Aquarium plants are the most common source of unwanted snails. They often harbor eggs or baby snails, which then reproduce once they’re in your tank. Fortunately, you can avoid putting infected plants into your aquarium by quarantining them for 2 weeks before putting them in your tank.
- If you see any snails during the quarantine period, pick them off the plant as soon as you notice them.
2
Treat plants in a 1:19 bleach-water solution before adding them to your aquarium. Create your bleach solution by adding 1 part bleach to 19 parts water. Then, dip each individual plant into the solution and immediately withdraw it. This will kill any lingering snails or eggs. Rinse the plant in fresh water before putting it in your aquarium.^{[19]XResearch source}
- You only need to submerge the plant in the solution for a second for it to work, so it's okay to just dip and remove the plant in one motion.
3
Clean the entire aquarium, including removing the gravel. You can purge all of the snails by hand if you have the time. Move your fish to a temporary tank, then empty the water from the aquarium. Remove everything, including the gravel and substrate, from the tank, then scrub all of the snails from the sides of the tank.
- Replace your gravel and substrate for best results.
- Before you put your plants and other fixtures back in the aquarium, clean them. One way to do this is to dip them in a cleaning solution that’s 19 parts water and 1 part bleach. This will kill any snails or eggs that are on them.
- If you don’t want to take everything out of the tank, you can use a siphon to suck out just the gravel and substrate. Additionally, you’ll need to pick the snails off the sides of the tank.^{[20]XResearch source}
4
Introduce fish that eat snails. Some fish eat snails and can clear out your tank for you. When selecting a predator fish, check its fact sheet to make sure it won’t eat your other fish. Additionally, make sure it’s not too big for your tank.
- For a small fish tank, you might choose a zebra or dwarf chain loach.
- If you have a large fish tank, you can choose a clown loach, pictus catfish, koi, or large goldfish.^{[21]XResearch source}
- As an alternative, you might place an assassin snail into your tank. It will enjoy eating the other snails in the tank and won’t reproduce often.
5
Put a snail trap in your tank to catch and remove the snails. A snail trap entices the snails to enter a cage then prevents them from leaving. This allows you to easily catch and remove all of the snails without harming your fish.^{[22]XResearch source}
- You can find snail traps at your local pet store or online.
- You can make your own snail trap by clipping a large piece of lettuce to the side of your tank. Leave it in place overnight, then remove it in the morning. It should attract a fair number of snails, which will now be gone from your tank!^{[23]XResearch source}
6
Add fish-friendly copper sulfate to your aquarium to kill the snails. Snails are sensitive to copper, so they will die if the water contains copper sulfate. Most fish are unaffected by copper sulfate, making it a safe option for most aquariums.^{[24]XResearch source}
- If you’re worried about your fish dying, check their fact sheet to see if they are sensitive to copper.
- Don’t use this treatment if you have shrimp or ornamental snails, as they are also sensitive to copper.
- You can find copper sulfate at a local pet store or online.

Question
Do coffee grounds deter snails?

Staff Answer
Coffee grounds may deter some species of slugs but their effectiveness as a deterrence is varied––some gardeners have found that snails and slugs just speed up to get past the grounds quickly. Caffeine sprays have been found to be effective when sprayed on leaves (snails don’t like such leaves)(Nature 2002), so in some cases it may be more effective to use the coffee grounds diluted in water as a spray. Using coffee grounds to deter snails is worth trying but realize it can impact beneficial insects as well, so keep an eye on how it works for your garden. To avoid acidity build-up in the soil, use used coffee grounds (neutral pH) rather than fresh (acidic).

Question
What is the juice/water ratio for the yeast and sugar trap? (alternate to beer trap)

Staff Answer
For the trap mentioned in the article above, 1 to 2 cups of water or grape juice would work, depending on the container size used. For another similar trap, using a standard jar, the suggested amount is: two cups of warm water, a packet of dry yeast, and one teaspoonful each of salt and sugar. For more detail on yeast traps, see How to Get Rid of Snails with Yeast.

Use a small 1lb container or tub to make peanut butter traps! Put a teaspoon of peanut butter in the bottom surrounded by a ring of salt. Slugs love peanut butter and will go right into the container to get the bait, dying in the ring of salt. If you smear a little vegetable oil about 1 inch up from the bottom it will help the slugs slide in better and make it harder for them to escape. Birds love to eat them in the morning too, and the trap won't hurt anything but slugs.
Do not sprinkle salt everywhere. Salt will kill all of your plants. You can, however, use it as a weed killer in the cracks of your driveway—just fill them with cheap rock salt.
