Place compost heaps away from vulnerable plants. But don't be too tidy as ground beetles like to hide during the day, large stones and pebbles will do for them. Keep them there with a concealed, dry home with straw bedding and don't light bonfires without checking for sleeping 'hogs. Beer cans can be quite effective, I discovered this when I lived near to a main road and late revellers used the front garden as a bin. They seldom finished the beer so the cans were already baited, the slugs crawled in and drowned in a stupor, I suppose.
Alternatives are grit, cocco shells, weathered cinders, wood ash or crushed egg shells.
Strips around pots would also be decorative. Phasmarhabditis hermaphrodita which occurs naturally and is used in Slugsure. They invade the slug and bacteria which they carry cause the slug to stop feeding, go underground and die. As they decompose the eel worms reproduce. I suppose it's like giving them the 'flu'.
