Slugs tend to arrive in force just as young seedlings are at their most vulnerable, and it is tempting to reach for the quickest fix available. Poison-based pellets, however, can affect far more than the slugs themselves, travelling up the food chain to hedgehogs, birds and other garden visitors that feed on them.
Simple barriers work surprisingly well against slugs, since many struggle to cross rough or dry surfaces. Crushed eggshells, sharp grit or coarse bark scattered around vulnerable plants can slow them down enough to protect young growth during the weeks when it matters most.
Timing and habitat make a real difference
Slugs are most active on damp evenings, so a quick torchlit walk around the garden after dark, removing slugs by hand into a container, can noticeably reduce numbers over just a few nights. It is a simple, low-tech method that many gardeners find genuinely effective once it becomes routine.
Encouraging natural predators such as frogs, toads and birds gives the garden its own ongoing pest control that works quietly in the background. A shallow pond, a log pile or simply leaving part of the garden a little wild all help these predators settle in and stay.
Watering in the morning rather than the evening leaves the soil surface drier by nightfall, which makes conditions less inviting for slugs when they are most active. Combined with a few physical barriers, this small change in routine often does more good than any single treatment applied on its own.
Raising the most vulnerable seedlings off the ground in pots or a raised bed, at least until they have grown a little sturdier, keeps many slugs away simply because the extra height and edge make the journey more difficult. Once plants toughen up, they can usually cope with a little grazing without lasting harm.
Checking under pots, boards and other flat objects lying around the garden often reveals exactly where slugs are sheltering during the day. Clearing away unnecessary clutter, or at least checking it regularly, removes some of their favourite daytime hiding spots without needing any further intervention.
