You can make a homemade snail repellent by mixing garlic and water in a spray bottle or pouring cold coffee into a spray bottle. You can then take that spray bottle out to your garden and spray your plants and the area around your plants to deter slugs and snails.

To effectively get rid of the ants and pest in your snail farm, do the following;

1. Securely cover your snail pens with mosquito nets.
2. Dig a trench around your snail farm and fill it with water.
3. Treat the soil in you snail farm.
4. Plant pest repellant plants.
5. Remove all leftover food to prevent ant invasion to your snail farm.

Vertebrate predators of snails and slugs include shrews, mice, squirrels, and other small mammals; salamanders, toads and turtles, including the uncommon Blandings Turtle Emydoidea blandingii; and birds, especially ground-foragers such as thrushes, grouse, blackbirds, and wild turkey.

Only a joke! I dont doubt ants can eat regular snails and slugs, but these slugs seems special since the seem to have very few natural predators, they must be avoiding the “killerslugs” for a good reason, anyway i will try to catch some “killerslugs” and feed it to a formica hill, i doubt the slug will win the battle.

Other Snail Predators Beetles, including the devil’s coach horse (Ocypus olens) and boat-backed ground beetles (Schaphinotus spp.), also attack and eat snails, leaving the empty shells to litter the ground.

Crushed eggshells, sand or diatomaceous earth sprinkled around plants that the garden snails seem to prefer will deter and eventually kill these pests.

Plants slugs dislike include:

• The Allium family – such as the Allium giganteum.
• Strong smelling mint.
• Chives.
• Garlic.
• Fennel.
• Foxgloves.
• Geraniums.

Caffeine kills slugs and snails. Coffee grounds are already recommended as a home remedy for keeping slugs and snails at bay. Grounds repel slugs, Hollingsworth found, but a caffeine solution is much more effective, he says: “Slugs turn back immediately after contacting the [caffeinated soil].”

Because of their slimy, moist bodies, snails thrive in environments that shelter them from the heat of the sun. They’re active on foggy, overcast, or rainy days, and will feed on a variety of plants in the yard or garden.

Seaweed. Seaweed, both fresh and powdered is a good home remedy for slugs, and it’s great for soil as well! Seaweed is a great natural repellent for slugs, and will help keep your garden free from slug damage.

Diluting brewed coffee with an equal part water is plenty to do the job. Coffee grounds have been recommended in the past as an organic method to keep slugs and snails out of your flower and vegetable beds. Grounds will repel slugs, but the USDA research team confirms that a caffeine solution is more effective.

Rather than by a complex chemical reaction, salt acts as a snail and slug’s kryptonite by dehydrating its slimy exterior. “Salt essentially draws the water out of their skin – an osmosis effect – and they die within minutes of dehydration,” says Dr Gordon Port, senior lecturer at Newcastle University.

So here’s my tried and tested top 10 ways to naturally control slugs and snails:

1. Coffee Grounds.
2. Beer Trap.
3. Eggs shells and sea shells.
4. Diatomaceous earth (DE).
5. Copper tape.
6. Slug repellent plants/Slug attractive plants.
7. Recycled wool waste pellets.
8. Nematodes.

Moist plant debris, underneath rocks, low weeds, mulch and fallen logs all provide hiding places for snails and slugs. Moist locations are especially attractive if a food source is nearby. Both a snail and a slug will eat plant leaves, flowers, and fruits, particularly those at ground level.

Are You Being Driven Mad by Slugs and Snails? Here are 7 Plants They Hate

• Ferns. Low maintenance, incredibly hardy and well down the slug and snail menu; ferns make an attractive, hassle-free addition to the garden.
• Hydrangeas.
• Euphorbias.
• Lavender.
• Rosemary.
• Geraniums.
• Japanese Anemone.

Many people suggest controlling slugs with salt. But salt will kill them, rather than simply control them. Making a direct slug kill using salt will draw out the water from a slug’s moist body, resulting in death by dehydration.

Dogs can get infected with lungworm when they come into contact with the slimy substance produced by slugs and snails – by eating them or by eating or licking surfaces where the slugs and snails have left a slimy trail. The disease affects dogs’ lungs and respiratory tract and is potentially lethal if untreated.

Slugs don’t scream or cry out, but they do have pain receptors like most other creatures.

THE SLUG has a moist skin, so when you sprinkle salt on to it a strong brine quickly forms. The process of osmosis then begins, by which water is drawn from a weak solution (in this case the body fluid of the slug) into a stronger one. Result: the slug dies a lingering death by dehydration.

In my opinion, it is not necessary to kill slugs and snails using any of the methods described above. There are much wiser ways to deal with the pests. You do not need to fight them directly. It is enough to ward them off passively; for example, with barriers against slugs and snails.

Infected slugs and snails also transmit rat lungworms to humans. All known cases of rat lungworm disease are linked to slug and snail contact. Slugs and snails can contaminate garden produce with rat lungworm parasites.

If slugs take a little chew out of your lettuce or a weevil leaves a small hole in your pepper, cut away the damage and thoroughly inspect what is left. If it all looks good, then feel free to eat the rest.
