Pests active at night are best controlled by regular night searches with torches, especially during damp evenings.
Beer traps placed in parts of the garden can be effective at catching slugs.
It's been proposed that spraying beer on weeds attract the slugs to the weeds, which they then munch down.
Diatomaceous earth, a fine powder that is very sharp microscopically and the edges easily cut through slug skin and desiccate them as they crawl over it. Replenish it after every rain or heavy dew.
Other barriers include hair, eggshells, soot and wood chippings.
Chickens and ducks will eat any slugs and snails that you have in your garden.
Hedgehogs and toads are the main predators of slugs and snails in the UK. Attract these garden predators to your green spaces by incorporating small water features (for toads) or habitats like a large pile of logs for hedgehogs. These animals adore wild patches of grass and dense undergrowth. Here, they can stay concealed. You’ll require some exit and entrance points too.
