Ive used nemaslug quite a few times in the past and its fantastic stuff, especially during periods like last year when there were the extended wet periods (that lasted almost the whole summer). The downside is that it is expensive, but I suppose it depends on how much you value the crops / hostas - there is nothing worse in my opinion than munching on a strawberry to find a juicy slug inside.
Chickys tip is spot on about applying it to borders, I would also apply it to your key crops e.g. Lettuce, Potatoes, Strawberries, hosta's if you have enough. The cheapest place I have found them is Nematodes Direct at 10.49 with free P&P.
