I have been reading about beer baths for slugs. I thought they just drank some of it and staggered off elsewhere. Seems they fall in actually.
It involves sinking a yogurt pot into various places where the slug has to travel to get to the goodies, filling it with beer, and waiting. The yogurt tub has to be level with the top of the soil. Greusome job disposing of the contents but everyone I have read about says it is brilliant.
Another tip from a lady on here is spent coffee grounds. Ask your local coffee shop for the grounds, spread them around the edges of the plants. Apparently slugs and snails hate walking on them.
Finally, and this sounds reasonably sensible to me, save all your egg shells. Wash them, pound them down to small pieces in a pestel and mortar or similar, then scatter these around the crops. The slugs dont like walking on sharp shells. Wonder if this would work with seashells also ?
Hope this helps. I am sure other more experienced gardeners will be along to add more.
Good luck.
