Spring is when your garden wakes up, and snails and slugs know it. Fresh seedlings, tender leaves, ripe strawberries: they’re not fussy, and one damp night can undo weeks of careful planting. If you’ve ever walked out to find a row of seedlings reduced to stalks and a silvery trail, you’re in good company.
The good news is you don’t need harsh chemicals to take your garden back. A few simple habits, a couple of well-chosen barriers and one gentle bait will do the job, and they’re kinder to your soil, your pets and the wildlife that share your patch.
Know your pest: where snails and slugs live
Snails and slugs need moisture to thrive and are most active in the wettest months. When it turns hot and dry, they tuck themselves away and bide their time, which is why they seem to appear out of nowhere after the first good rain.
The troublemakers in your garden are introduced pests, so you can act without guilt. Australia does have native snails and slugs (the Cystopeltidae and Athoracophoridae families, for example), but they aren’t garden pests and they aren’t what’s eating your lettuce.
What are they after?
Just about everything soft: leaves, tender stems, flowers and ripe fruit. Seedlings are their favourite, especially when they’re newly planted out and already coping with transplant shock. A seedling can be demolished overnight, so get a twiggle on and have your defences in place before you plant out, not after.
Our organic-first approach
We’d always rather you reach for the gentlest option that works, and keep the stronger stuff as backup. Here’s the order we’d tackle it in.
1. Remove their hiding places
Start with a tidy-up. Snails and slugs shelter and breed in damp, shady spots, so clear out empty pots, weeds in shady corners, and piles of wood, bricks and rocks. It costs nothing, and it’s one of the most effective things you can do because it takes away their home base.
2. Go on patrol after rain
You’ll probably squash a few during the clean-up, but some will stay hidden. Get into the habit of a quick patrol straight after rain, when snails and slugs are active and easy to find. Look for their slime trails and clusters of gelatinous eggs, and remove them. An evening wander through the freshly watered garden is a pretty good way to end the day, too.
3. Invite the predators in
Frogs, lizards, chooks, ducks and other birds find snails and slugs irresistible. If it’s practical for your space, encourage as many of them into your garden as you can. It’s pest control that runs itself.
4. Wrap pots and planters in copper tape
Thin adhesive copper tape is a barrier that repels snails and slugs without killing them, which makes it a friendly, chemical-free option. They simply won’t cross it. Run a continuous line around your pots or planter boxes with no gaps. Bigger snails can push past thin tape, so you may need two widths to cover your bases.
5. Set a beer trap
My grandad’s favourite trick: fill a snail & slug trap, saucers or jars with beer (yes, beer!) and place them around the garden at soil level. Snails and slugs like beer and will be easily attracted to it, they end up drowning in it. To keep it working, empty, clean and refill your traps regularly.
6. Keep eco bait as your backup
When the pressure is on, like a seedling bed or veggie patch under heavy attack, an eco-friendly bait is your safety net. Eradicate Eco Snail & Slug Bait uses elemental iron as its active ingredient, which is gentler on the environment and doesn’t accumulate in it. Scatter it around the seedlings, veggies and other plants you want to protect, and reapply after heavy rain.
If pet-safe pellets are your priority, Eradicate Snail & Slug Bait is also an option. Apply it the same way.
What doesn’t work (so you don’t waste your money)
You may see recommendations for diatomaceous earth, sawdust, powdered lime, crushed eggshells and wood ash. In our experience, these aren’t very effective. To have any chance, the material needs to go down as a continuous, thick band and stay completely dry so it can draw moisture out of the snail or slug. Even then, we’ve often watched snails slide straight over it.
Salt will kill slugs and snails, but it’s bad for soil health, so please leave it in the kitchen.
When to Apply Bait
Timing makes all the difference. Bait works best when snails and slugs are active and feeding. Lightly water the area first to encourage them out, then apply the bait in the late afternoon or evening. Place it around their hiding places, along the paths they take to reach your garden, and in the garden itself. They aren’t active during the hottest, driest or coldest stretches, so there’s no need to bait then.
Keep it kind to the planet
Whichever methods you choose, your order from us arrives in biodegradable packaging, so fixing the problem doesn’t create new waste.
