How to Get Rid of Slugs in the Garden – Top Tips

Slugs are a natural part of any garden ecosystem, but when hungry slugs become particularly active, they can cause significant damage in a very short time. Especially during the wet summer of 2025, many amateur gardeners are discovering just how quickly slugs can strip their beds, nibble young plants, and even devastate delicate herbs. Molluscs such as slugs thrive in moist conditions and are drawn to densely planted gardens, compost heaps, and decaying plant material. If you want to get rid of slugs effectively and sustainably, you need to know that not every method works equally well — and many common approaches can actually attract even more slugs.

Checking for slugs occasionally is rarely enough, as slugs lay their eggs hidden in moist soil and are remarkably resilient survivors. If they are not discovered early and removed regularly, slugs can multiply rapidly as pests and cause repeated damage throughout the season. In this guide from FUXTEC, you'll find out which measures really work, how to tackle slugs and keep your garden free from them, and which plants slugs particularly love — or can't stand. You'll also learn how to keep slugs away effectively and how to tackle the problem for good using straightforward methods.

Why Slugs in the Garden Are a Problem

In any wildlife-friendly garden, slugs are part of the natural landscape. But especially during wet summers, when regular rainfall keeps the soil saturated, harmless slugs can quickly become a real nuisance. Particularly hungry slugs will work their way through lettuce, courgettes, strawberries, and other garden plants. As these molluscs are nocturnal, gardeners often don't notice the damage until the following morning. They love damp conditions because moisture makes it easier for them to move around and prevents their bodies from drying out. In gardens with dense planting and plenty of food on offer, a slug problem can escalate quickly.

Types of Slugs in the Garden – Identifying Slugs and the Spanish Slug

Not every slug is harmful to your garden: shelled snails are actually considered beneficial and mostly feed on dead plant material. The real culprits are slugs — in particular the Spanish slug (Arion vulgaris). This species is especially voracious, hardy, and capable of travelling considerable distances, meaning it can easily migrate in from neighbouring gardens. The Spanish slug can lay up to 400 eggs per season, usually deep in the soil or hidden beneath planks and stones to protect them from drying out. Given sufficient food and moisture, slugs can become a serious infestation within just a few weeks.

Recognising Slug Damage to Beds and Plants

When slugs feed on plants, they leave characteristic signs: ragged edges on leaves, large holes, and occasionally completely eaten seedlings. Young plants in the border are usually the first to be attacked by hungry slugs. Damage to strawberries, cabbages, or squash is also typically easy to spot. If you discover slimy trails and eaten leaves in the vegetable patch in the morning, slugs have almost certainly been at work. Particularly during wet summers, when food is plentiful, slugs can cause considerable damage and threaten the harvest.

Controlling Slugs in the Garden – Tips for Getting Rid of Slugs

Successfully controlling slugs in the garden requires a combination of different approaches. The golden rule is: the earlier you act, the better! Hand-picking slugs on damp evenings or early mornings is often highly effective. Scarifying the soil at the start of the gardening season is also well worthwhile, as it removes the creatures along with their eggs from their hiding places and renders them harmless. Slugs particularly like to shelter under planks, pots, or thick layers of mulch. Regular hand-picking can keep a slug problem well under control.

Among the most important natural predators of slugs are hedgehogs, toads, Indian runner ducks, and various species of birds. To encourage these allies in the garden, it is worth creating refuges such as leaf piles, hedgerows, or compost areas. These provide shelter for predators that help deter slugs. If you plan to keep Indian runner ducks, do your research first — they are enthusiastic slug hunters but do require appropriate living conditions and space.

Hand-Picking Slugs – Immediate Action Against Slugs

Targeted hand-picking is a tried-and-tested tip that many experienced gardeners use regularly. Slugs emerge from their hiding places during rain or on damp days, making hand-picking particularly successful at these times. Place planks, leaves, or old roof tiles in the bed — they attract slugs as daytime hiding spots and make collection much easier the following morning. Consistent hand-picking ensures slugs are caught before they spread through the garden or lay their eggs. Important: collected slugs should not simply be tipped into a neighbouring garden or onto the compost heap; instead, dispose of them as far away as possible or in a humane manner.

Home Remedies for Slugs – What Really Works Against a Slug Infestation?

There are many home remedies said to deter slugs, but not all of them are equally effective. Coffee grounds, for example, are thought to repel slugs because the caffeine causes cellular changes in their digestive system — though this effect remains contested. Crushed eggshells, sawdust, sheep's wool, or coarse grit are also spread around plants to keep slugs at bay. These materials irritate the sensitive underside of slugs and make movement more difficult. Important: after rain, these barriers need to be refreshed, otherwise they lose their effectiveness. Beer traps attract slugs, but they often draw in slugs from neighbouring gardens as well, resulting in larger numbers drowning in the beer. This may offer short-term relief, but it is rarely a lasting solution. Many myths circulate, but the most effective home remedy remains consistent hand-picking combined with barriers and natural predators.

Slug Pellets and Other Slug Control Products

When a slug infestation is severe, many gardeners turn to slug pellets. There are different active ingredients available: metaldehyde is toxic to other wildlife and should be avoided in a wildlife-friendly garden — it has in fact been banned for amateur use in Great Britain since 2022. A more environmentally friendly option is ferric phosphate-based slug pellets, which are safe for hedgehogs, toads, and other natural predators, and break down in the soil. It is important never to scatter slug pellets broadly across the garden; instead, apply them sparingly and precisely around particularly vulnerable plants. You can also dissolve slug pellets in water and spray the solution directly around areas of your garden threatened by slugs. That said, slug pellets should always be just one element within an overall slug control strategy.

Slug Barriers, Fences, and Further Methods Against Slugs

Barriers such as slug fences made from metal or plastic offer effective protection against slugs when installed seamlessly around a bed. Slugs cannot cross smooth or sharp-edged slug fences, keeping plants safely protected. Copper tape is also a deterrent for slugs, as contact with it produces a small electrical impulse. It is important to check barriers regularly and clear them of leaves or soil so that slugs cannot find a way over them. Layers of bark chippings or straw mulch also make movement more difficult for slugs, though they become less effective after rain. Consistent use of barriers can keep your garden free from slugs in the long term.

Indian Runner Ducks in the Garden – Natural Slug Control

Indian runner ducks are natural predators of slugs and can help significantly reduce hungry slug populations during a severe infestation. They eagerly hunt slugs and will even dig into the soil in search of eggs. However, Indian runner ducks are not a cure-all — they need access to water, sufficient space, and protection from predators. They should also not be left permanently in the vegetable patch, as they can damage young plants. Anyone considering this natural approach to slug control should research Indian runner duck husbandry thoroughly and deploy them strategically during periods of peak slug activity.

Beer Traps and Other Traps – How Effective Are They Against Slugs?

Beer traps are one of the best-known methods for dealing with slugs and are often recommended as a classic remedy. They lure slugs in, which then drown in the beer. The drawback is that the traps often act like a magnet for slugs from neighbouring gardens, potentially making the problem worse rather than better. Beer traps can also pose a risk to hedgehogs and other beneficial wildlife. If you do use traps, sink them into the soil so only the rim is above ground and check them regularly. Other traps — using melon or cucumber rind as bait — offer a less invasive, but similarly limited effect. Overall, traps alone are rarely sufficient, but they can be a useful addition to a broader slug control strategy.

Preventing a Slug Infestation – Sustainable Slug Control in the Garden

If you want a slug-free garden, prevention is key. Varied planting, regular digging over, and removing hiding places such as planks or stone piles all help to keep slugs away. Plants such as nasturtiums or ferns tend to be avoided by slugs, whereas lettuce, courgettes, and marigolds are firm favourites. Raised beds, mulch, and companion planting offer additional protection against slugs by promoting balance in the garden. Encouraging hedgehogs, toads, and other natural predators in your garden brings double benefits: they help maintain a balanced ecosystem in the long term and sustainably reduce slug numbers. A wildlife-friendly garden offers many advantages and is the best foundation for keeping slugs under control year after year.

Summary – Keep Your Garden Slug-Free With These Tips

With a combination of hand-picking, natural predators such as hedgehogs and toads, the targeted use of barriers and slug pellets, and tried-and-tested home remedies, effective slug control is achievable even during the wet and rainy summer of 2025. The key is to adapt your approach regularly and introduce new helpers to the garden as needed. That way, your garden stays protected from hungry slugs and the pleasure of gardening remains undimmed.
