5 Proven Ways to Get Rid of Snails & Slugs in Your Garden
They come out at night, they love your rarest plants, and they leave nothing but holes and slime trails behind. Here's how to fight back β naturally.
If you've ever walked out to admire your garden, only to find your orchid's tender new shoots or your anthurium's fresh leaves full of ragged holes β you're not alone. Snails and slugs are likely the culprits. These sneaky night-time feeders have a special love for soft, new growth, which is why your most delicate plants often become their favourite snack.
In this guide, we'll break down exactly what draws them to your plants, and give you 7 tried-and-tested, eco-friendly ways to show them the door β for good.
π How to Tell if Snails or Slugs Are the Culprit
Irregular, chewed holes in leaves β especially new, soft growth
Shiny, dried mucus trails across leaves, soil, and pots
Damage appears in the morning β they feed at night or in damp weather
Young plants or fresh shoots disappearing completely overnight
What Attracts Snails & Slugs to Your Plants
Snails and slugs don't just show up by chance. They follow a mix of physical and chemical signals that tell them, "Hey, there's a feast over here!"
Tender, Moist Plant Tissue
Soft, succulent new leaves and shoots are easy for them to chew through. Mature leaves are tougher and far less appealing β which is why your orchids and anthuriums show the worst damage exactly where growth is freshest.
Moisture is Everything
Snails and slugs thrive in damp conditions. They love freshly watered soil, dewy mornings, and shaded, humid corners. Moisture not only keeps them hydrated but also makes surfaces soft enough for easy movement and feeding.
Chemical Signals
When plants push out new leaves, they release natural compounds β kind of like a "fresh growth" scent. Snails and slugs can detect these signals and follow them straight to the tastiest, most nutritious parts of your plants.
Yes, snails genuinely love beer! Sink a few shallow containers (old yogurt cups or tuna tins work perfectly) into the soil so the rims sit level with the ground, then fill them about halfway with any cheap beer. The yeasty aroma draws snails and slugs in irresistibly β and once they climb inside, that's the end of the story.
Place traps wherever you spot the most damage, and refresh them every 24 hours for best results. The traps work best when placed in the evening, just as these night-feeders become active.
- Works overnight
- Extremely cheap
- No chemicals involved
- Easy to set up anywhere
- Needs daily refreshing
- Unpleasant to empty
- Ineffective in heavy rain
Your morning brew can double as garden armour. Sprinkle used coffee grounds around the base of your most vulnerable plants β snails and slugs can't stand the gritty texture, and the caffeine in the grounds is genuinely toxic to them at close contact.
You can also make a coffee spray: mix one part brewed coffee with nine parts water and apply it to the soil surface around your plants. This repels pests on contact and, as a bonus, gives your soil a gentle nitrogen boost as the grounds break down.
- Free from your kitchen
- Adds nitrogen to soil
- Repels AND kills on contact
- Pleasant smell (for humans!)
- Needs reapplication after rain
- Can acidify soil over time
- Less effective against heavy infestations
Don't toss those eggshells! Crush them into jagged pieces and scatter a generous ring around the base of your most vulnerable plants. The sharp edges are uncomfortable for snails and slugs to cross β their soft, exposed undersides are sensitive to abrasive textures, making the barrier an effective deterrent.
As a bonus, the crushed shells slowly break down and release calcium back into your soil, strengthening plant cell walls and improving overall plant health. Truly zero-waste gardening at its best.
- Completely free
- Improves soil calcium
- Zero chemicals, zero waste
- Needs replenishing regularly
- Loses effectiveness when wet
- Mixed results reported
It's not glamorous β but it genuinely works. Head out in the garden with a torch about an hour after sunset, or just before dawn, when snails and slugs are at their most active. Pick them directly off your plants, wearing rubber gloves, and drop them into a bucket of soapy water.
If you prefer a more humane approach, relocate them to a patch of wild vegetation at least 20β50 metres away from your garden β studies suggest that most snails won't travel that distance to return.
- Completely free
- Instantly effective
- No chemicals at all
- Good for small gardens
- Time-consuming
- Must be done regularly
- Not for the squeamish!
Diatomaceous earth (DE) is a gardener's best-kept secret β a fine, white powder made from the fossilised remains of microscopic aquatic organisms called diatoms. To snails and slugs, it's lethal: the microscopic sharp particles get into the joints of their soft bodies and cause rapid dehydration. To pets, children, and pollinators, it's completely harmless.
Sprinkle a generous ring of food-grade diatomaceous earth around vulnerable plants and along garden bed borders. Reapply after every rain β once wet, it loses its effectiveness until it dries again.
- Highly effective
- Safe for people, pets & pollinators
- No chemicals
- Works as liquid spray too
- Must reapply after rain
- Needs purchasing
- Loses potency when wet
Here's a fascinating bit of garden science: when a snail or slug's slime touches copper, it creates a small electrical charge β an uncomfortable reaction that makes them immediately reverse course. Copper is one of the few materials that acts as a true physical and chemical deterrent in one.
Wrap self-adhesive copper tape around the rims of plant pots β at least 4β5 cm wide for it to be effective against larger snails. It also works along the edges of raised garden beds and wooden planters. For best results, ensure there are no overhanging leaves that could act as a bridge over the tape.
- Lasts months or years
- No reapplication needed
- Excellent for potted plants
- Completely non-toxic
- Upfront cost to purchase
- Large snails can arch over thin tape
- Overhanging leaves can bypass barrier
Prevention is always better than cure β and one of the most elegant long-term strategies is to grow plants that snails and slugs genuinely dislike right alongside your vulnerable specimens. Strong-scented plants like mint, lavender, rosemary, and garlic naturally confuse and repel these pests, acting as a living, beautiful barrier.
Slugs and snails actively avoid plants with rough or leathery textures β ferns, geraniums, and salvias are all known to be highly resistant. Planting a ring of these around your prized orchids or rare tropicals creates a natural first line of defence while making your garden look lush and layered.
- A permanent, self-sustaining solution
- Makes your garden more beautiful
- Many plants are useful herbs too
- Attracts beneficial insects
- Takes time to establish
- Needs garden space
- Works best as prevention, not cure

π€ Which Method is Right for Your Garden?
Answer one quick question and we'll point you in the right direction.
πΊ Start with Beer Traps + Handpicking Tonight
Set 3β5 beer traps across your garden this evening and do a torchlight handpicking session an hour after sunset. This will dramatically reduce your active pest population overnight. Follow up with Diatomaceous Earth around your most vulnerable plants the next morning.
πΆ Copper Tape is Your Best Friend
Wrap copper tape (at least 4β5 cm wide) around the rim of each pot β this creates a permanent, virtually maintenance-free barrier. Combine with a light sprinkling of coffee grounds on the soil surface for double protection.
β Coffee Grounds + Eggshells + Handpicking
This three-pronged, zero-cost approach is highly effective: collect used coffee grounds daily and ring your plants, crush eggshells around the base, and do a quick handpicking session every evening at dusk. Completely free, completely natural, and very effective with consistent effort.
πΈ Companion Planting + Copper Tape
Plant a ring of mint, rosemary, or marigolds around your garden beds as a permanent living barrier. Add copper tape around your most prized pots. These two methods, once established, require almost no ongoing effort and get more effective over time.
π‘οΈ 5 Habits That Keep Snails & Slugs Away Long-Term
Water in the morning so soil has time to dry by evening β slugs hate dry surfaces and are most active when the ground is damp at night.
Clear debris regularly β remove dead leaves, old mulch piles, and overturned pots. These are prime daytime hiding spots for snails and slugs.
Wait before planting seedlings β slugs love very young plants. Wait until seedlings have 6β8 leaves and some leaf toughness before moving them to exposed beds.
Encourage natural predators β a small garden pond attracts frogs and toads, which are voracious slug eaters. Birds, lizards, and hedgehogs also help keep populations in check.
Do a weekly torchlight check β a 10-minute patrol an hour after sunset, once a week, prevents populations from getting out of hand before they become a serious problem.
