Snail Control Products

Pellet treatments, barrier methods such as copper tape and barrier granules, plus traps to help monitor and reduce activity. The best choice depends on where you need protection - pots, beds, borders, patios or allotments - and how persistent the problem is.

Ferric phosphate. Metaldehyde pellets have been banned for outdoor use in Great Britain since 2022, so anything you buy now uses ferric phosphate instead. Always read the label and follow the stated dosage; scattered pellets should be thin and spread rather than heaped.

Suitability varies by product type. Always read the label and use as directed, and keep children and pets away from treated areas as instructed. If you want to reduce exposure risk, consider traps or barrier methods such as copper tape, and place any treatments securely and only where needed.

Focus on damp hotspots and hiding places: around the base of vulnerable plants, under pots, along bed edges, near fences, and anywhere you see slime trails. Place traps near cover and along likely routes. Apply copper tape around clean, dry rims of pots, planters or raised beds for a continuous barrier, and follow the label for placement and dosage of any pellets or granules.

Snails are most active in the evening and early morning, especially after rain or watering. Treating at dusk and targeting sheltered, damp areas often improves results. Reapply only as directed on the label - some products may need reapplication after heavy rain or watering, while barrier methods like copper tape can continue working when installed properly.

It depends on your garden and the pressure level. Pellets can be useful for targeted treatment, used only as directed. Barriers like copper tape and granules help reduce access to vulnerable plants, and traps support monitoring and capture in problem areas. Many gardeners get best results by combining a barrier around key plants with targeted treatment only where activity is highest.

Two different symptoms. If damage appears on plants right next to a barrier, check the barrier is continuous and that no leaf or stem is bridging it - a single leaf touching a wall or another pot gives a route straight over the top. If damage is spread across the bed, they are sheltering in the bed itself rather than travelling in; target the damp harbourage under pots, slabs and debris instead and treat at dusk when they are active.
