If I went out every night at about 11 p.m. in the summer I would find slugs. 110 was my record, to be fair some nights I will only find about 8. But every night they will be there. I wouldn't mind but next door but one to me is a totally overgrown garden where they could chomp to their hearts delight, but they seem to prefer my garden.
I also sink large yoghurt pots into the soil with some beer in the bottom, if I don't go out some nights (and to be fair some nights I just can't be bothered) then there will be loads of slugs in them in the morning. I usually put at a couple in each flower bed, but don't worry once the slugs get a whiff of beer they will travel.
I have been known, on warm balmy summer nights, to hover around the yoghurt pots to catch the slugs on their way in. That way there is more room for the ones who will visit once I have gone to bed.
I know, I am sad. As I said before, OH thinks I am mad.
I can remember once trying Bargain Booze to see if they had any cheap beer. As I seemed to be spending quite a time checking the beer shelves, the manager came to ask me if he could help. I told him I was looking for the cheapest beer he had. He looked a bit surprised so then I told him what I wanted it for. Bless him, he went into the back and came out with a load of cans which were out of date and gave me them for free.
