Nematodes

I don't like using anything 'chemical' or 'introduced' if there's another way (cheapskate!)
So, once the weather starts to warm up, I'm out there with a torch and a piece of slate - triangular - flat bit to make the snails two-dimensional, and the sharp edge to make the slugs into two!
Any others spotted during normal gardening get an instant flying lesson into the field over the road.
After a week or so, the numbers diminish to easily manageable proportions. But you must keep on top of the slimy beasts.
Incidentally, my compost heaps are always full of slugs - variety of great big yellow, black and grey ones.
You'll never be completely free from pests, just keep 'em under control.

Build a shallow pond no more than 2.5 foot deep and in the region of 600-1000galls, put in a bit of oxygenating weed.
Build in some cover round the edge-old logs etc.
Wait for frogs to colonise--remarkably quickly normally
Next year you may find a slug or 2 but not many.
Once local birds, esp thrushes, realise they can get an undisturbed early morning drink, very few snails either.(plenty of smashed shells on the favorite stone )
This has worked for me for years.
All you need to do is to clean all the detritus out every couple of years in the late autumn.
Hope this helps.

I usually grab a four pint empty milk container (with the lid) and nightly go out armed with a torch and wearing a pair of gloves and collect as many slugs and snails I can get my hands on, filling the empty milk container. Once I have either run out of slimies or got bored, I screw the lid on and put them in the wheelie bin for the dustmen to take away.

I have found this is the ONLY way to remove them as far away as possible.
