This isn’t their only beneficial purpose, but it is a start. Here are some of the stories you hear about snails in the garden, and how they can tell the weather.

Black snails crossing your path means rain is on its way. If you see snails climbing up trees, this is a sign of hot weather.

Bad Sides of Snails and Slugs

When you begin to look at the negatives of having these, you can see they are bad for the garden in various ways.

When you are at ground level, these slugs and snails don’t hurt gardens. It is when they climb, they cause trouble.

Snails can climb trees and shrubs, among other things, and will eat flowering buds. Fruit trees are another favorite where they begin eating fruit as it ripens.

How to Manage Snails and Slugs in Your Garden

There are ways; you can help deter slugs and snails in your garden. During the day, they never travel far and leave activity for the night.

Both of these land mollusks like sticks, mulch, and dead plant matter, so rather than mulching around your garden in the spring, you are better to leave it until summer once the activity of these slithering things ceases.

You can keep a buffer area of dry, bare soil around your garden perimeter for starters. Many experienced gardeners will create the ideal slug and snail real estate areas with wooden boards, upside down pots, and odd bits of lumber.

They don’t do this for the comfort of the pests; they will gather them and drown them in soapy water before disposing of them.

Aside from this, there are the poisons, baits, and traps, which is what we will see here.

Alternative Methods to Control Slugs and Snails

The common means of dealing with slugs and snails are as follows.

Gritty Pathways: Both slugs and snails don’t like to crawl over gritty substances. It is the friction; their slime aims to overcome. However, there are things you can sprinkle around your veggies that stop them in their tracks.

Get a load of crushed eggshells or diatomaceous earth. Sprinkle this around your plants, and you will see slugs and snails keep away. Be sure not to leave gaps they may find and sneak through to your plants.

Used coffee grounds are found to be toxic to slugs and snails. Use these to repel these pests by sprinkling it around the edges of your veggie garden.

You will need re-applications of anything like this in temperate climates where it may be warm and wet. These solutions will be washed away.

For raised gardens or containers and pot plants, you can create barriers that are proven to stop snails and slugs.

Planter rims can be smeared with a solution of salt and Vaseline. This stops them from hiding in one of their favorite places.

One of the best solutions to stop these pests from climbing is through the use of copper tape. You can purchase this online, and as the copper slowly oxidizes, it releases salts that these pests don’t like.

You can opt for a snail killer that contains iron phosphate. These are safer when kids are around, and they are effective.

However, not every gardener wishes to use more chemicals in their pest management process.

Inviting Predators to the Snail Party

You can find there are many things that like to feast on snails and slugs. If you like snakes, then you can introduce the small garter snakes. These, though, can deliver a good or bad impression depending on how you look at them.

Other things that like to feast on these brown snails are hedgehogs, moles (you don’t want moles), toads, and frogs.

However, one other beneficial pest; can help you control your slug and snail population.

Decollates eat the brown garden snail. Using snails to keep snail population down is one of the better ways, if not being on the slow side.


If you look, at what are slugs good for? There isn’t much apart from breaking down dead matter into great fertilizer. The issue being, you can‘t have these in one area of your garden without them wanting to venture toward your veggies.

Any gardener is better to take some precautionary measures and go through their garden to set traps and introduce the right kind of beneficial pests or other animals that can help to prevent these from your vegetable garden.

One of the most interesting replies so far is that these snails are the same as they eat like a French delicacy, so if you fancy eating snails, you can handpick them and have them for dinner.
