Snails in gardens, houses or fish tanks are really annoying. If left unchecked, these snails will eat plants, make mucus everywhere, or occupy the whole fish tank. Fortunately, there are many natural and chemical methods to remove snails, protect lawns and prevent houses from being invaded by snails.

Method 1: Remove snails.

1. Catch snails with beer. Pour the beer into a small container, such as an empty tuna can. Bury the container in the garden or where snails are infested, at least 2.5 cm away from the soil. The smell of beer will attract snails to climb into the container and drown. Yeast can be added to make beer more attractive to snails.

Beer can only attract snails nearby, so it may be necessary to set more traps.

You can also put beer in plastic cups, yogurt cups, bowls or pie plates.

Don't bury the container flush with the soil to avoid killing other beneficial insects by mistake.

2. You can catch snails and exile them when you have time. Snails are most active in the morning or at night. You can catch them at these times. Put the snail in a bucket or container, and then take it elsewhere and set it free. You can also kill snails.

In order to speed up, you can put an inverted pot near the garden or where snails are infested. Snails are probably hidden in the pot, so that you can find them and catch them all.

3. Spray snails with cold coffee. Caffeine in coffee is lethal to snails, so spraying them with coffee can kill them. Spray snails until they die, so be sure to spray a lot of coffee. Make a pot of coffee and let it cool. Pour coffee into a spray bottle and spray snails in the garden or house.

4, homemade garlic spray to drive away snails, and maybe kill them. Spray garlic spray in gardens, courtyards and houses when necessary. If snails are found, they can also be sprayed directly until they are soaked. Garlic spray can drive away snails and even kill them. Crush 3 cloves of garlic and soak in 1 tablespoon (15ml) vegetable oil overnight. Filter garlic and mix the liquid with 1 liter of water. Pour the mixture into the spray bottle. Add 1 teaspoon (5ml) soap solution and shake well before use.

5. Kill snails with iron phosphate. Iron phosphate can kill mollusks such as snails and slugs. Place traps near gardens or places where snails haunt, and they will be attracted by bait. Snails will die if they come into contact with iron phosphate. You can buy iron phosphate at your local gardening center or online.

Iron phosphate can cause snails to stop eating, but it may take up to a week to die.

Iron phosphate is the safest bait because it is non-toxic to humans and pets.

6. Quickly kill Oncomelania hupensis with the molluscicide containing sodium ferric EDTA. Scatter it around the snail infested place at night, and a thin layer will do. In this way, when snails haunt at night, the bait remains fresh. Snails are attracted by the bait in the molluscicide and will die within 3 days after swallowing. This product can usually be used safely in the yard, but please keep away from children and pets.

Just sprinkle a thin layer. Don't put too much, lest other animals get sick or die after eating by mistake.

7. Keep a chicken to help eat snails. Chickens like snails very much. Keeping a chicken in the courtyard or garden can naturally control snails. Chickens will help you find snails hidden in the yard and destroy them without hands. Ducks also eat snails, but they prefer slugs.

Understand the local laws and regulations first, and ensure that you can raise chickens in your own yard.

8. Encourage natural enemies of snails to live in your garden or yard. Natural enemies of snails include frogs, toads, turtles, birds, opossums and snakes. Choose the natural enemies to be introduced according to your environment, and consult the local agricultural extension department or gardening club to find out the biological control methods suitable for your location. They will recommend plants or shrubs suitable for your growth and teach you to build natural habitats such as rock courtyards. You can also search online how to encourage natural enemies of snails to live where you live.

Method 2: Stop snail activities.

1, water in the morning to prevent snails from laying eggs. Snails need to lay eggs in wet soil. They usually lay eggs at night, so you need to dry the soil before dusk. Choose to water in the morning. After the sun is exposed during the day, the soil should be dry at night. It is best to use drip irrigation system or drip irrigation pipe to control soil moisture and prevent snails from laying eggs.

2. Remove damp and rotten organic matter from the courtyard and garden. Snails will be attracted by these rotten and moist organic matter, and if they are not removed regularly, they will definitely attract snails. Check the yard and garden at least once a week, and throw these organics into the trash can or compost. Compost is like a snail's carnival feast. Put the compost away from the courtyard and garden, and set a barrier around it that snails can't cross to prevent them from approaching.

Set a barrier around the garden or house that snails can't cross to prevent them from approaching. Suitable choices include broken eggshells, diatomaceous earth, sand and gravel, wood ash and pine sawdust. Snails are difficult to climb over these things, so it is suitable to prevent snails from approaching. Just sprinkle a thin layer where you want to stop snails. The easiest way is to break the eggshell and scatter it in the garden.

You can also buy diatomite, gravel, wood ash and pine sawdust at the local gardening center or online.

Sprinkle some leftover coffee grounds around the garden and drive away snails with caffeine. Snails are sensitive to caffeine and will naturally avoid it. Scatter coffee grounds on the soil or ground around the house as needed. If you don't drink coffee, you can ask at the local coffee shop. Maybe they can give you the rest of the coffee grounds.

5. Use copper wire or copper tape to stop snails from moving around. Copper will make snails feel slightly electrocuted, so they will instinctively avoid copper. You can stick copper bands around potted plants, on the edge of gardens or where snails are infested. If you choose to use copper wire, you can use it to tie a flowerpot or surround the garden. You can also sprinkle some copper coins.

Copper strips can be bought at local gardening centers or online.

6. Plant plants that can drive away snails naturally. This includes foxglove, spurge, autumn peony, day lily, succulents, celery, sage and fennel. These plants give off a smell that snails don't like, or it is difficult for snails to climb over them. Plant these plants in the garden or house, and snails will not come. For example, you can put potted plants in places where snails are infested.

Remember, foxglove is poisonous. If you have children and pets at home, it may not be suitable for planting.

Method 3: prevent water snails (snails) from invading the fish tank.

1. Isolate the plants for two weeks, and then put them in a fish tank. Plants in fish tanks often hide water snails, which are snails. These plants usually hide snails or snail eggs, and they will begin to reproduce when they enter the fish tank. As long as the plants are isolated for 2 weeks and then put into the fish tank, you can avoid bringing plants and snails into the fish tank. During the quarantine period, snails will be taken away once they are found.

2. Treat the plants with bleaching solution, and then put them in the fish tank. Mix bleach and water according to the ratio of 1: 19, then soak each plant in the solution and take it out quickly. This can kill the remaining snails or snail eggs. Rinse the plants with clean water before putting them in the fish tank. As long as the plant is soaked in bleach solution for one second, it will work and complete these actions in one go.

3. Clean the whole fish tank, including gravel and bottom sand. If you have time, you can start catching all the snails. Transfer the fish to the temporary water tank, and then empty the water in the fish tank. Take everything out of the fish tank, including sand and bottom sand, and then wipe off the snails stuck to the tank wall. It is best to replace gravel and bottom sand.

Be sure to clean up plants and other fixtures before putting them back in the fish tank. One method is to soak in bleach solution prepared according to the ratio of 1: 19. This can kill snails or snail eggs that stick to it.

If you don't want to take everything out of the fish tank, just suck out the sand and bottom sand with a siphon. Then start to grasp the screws on the cylinder wall one by one.

4. Raise fish that can eat snails. Some fish will eat snails to help you protect the fish tank from snails. Before choosing a fish to keep, check the information to make sure that it won't eat other fish, and that it is the right size to keep in your aquarium. If it is a small fish tank, you can raise striped thin loach or small loach.

If it is a big fish tank, you can keep clown fish loach, catfish, koi fish or big goldfish.

You can also put the killer snail in the fish tank. It likes to eat other snails in the fish tank and doesn't breed often.

5. Put a snail trap in the fish tank. Snails will be attracted to climb into the cage and never get out again. You can easily take the snail out of the fish tank without hurting the fish. You can buy snail traps at your local pet store or online.

You can also make your own snail trap. Put a large piece of lettuce on one side of the fish tank, leave it overnight, take it out the next morning, and take away the snails attached to it.

6. Add copper sulfate harmless to fish to kill snails. Snails are allergic to copper and will die in water containing copper sulfate. Most fish are not affected by copper sulfate, so they can be used safely in most fish tanks. If you are worried that fish will die, you can check the information to confirm whether it is sensitive to copper.

If there are shrimps or decorative snails in the fish tank, this method cannot be used because they are allergic to copper.

You can buy copper sulfate at the local pet store or online.

Tip: If you don't have time to deal with snail infestation, you can contact a pest control company. They should be able to help you remove snails.

Warning not to kill snails with salt, which will destroy plants and soil in the courtyard or garden.

Use coffee grounds carefully, because they will affect the pH value of the soil.
