I saw this stuff, Fito Slug Stoppa, in Lidl today for about 1.30 a box: http://www.webbsdirect.co.uk/product.asp?pf_id=161805Looks good, it's a 'barrier method' - the slugs can't crawl over it - rather than a toxin. Might go and get a few boxes tomorrow, bound to come in handy. But probably doesn't help much in this sort of case, where they magically appear from the soil... I'll just have to be more careful in preparing pots and compost for seedlings.
