Beer IS an answer

Despite my best efforts with coffee, pine needles and the torch, our weather cycle of a few warm days and then a few wet ones means that it is a constant battle to beat the slugs. I really do not want to use derris dust if I can possibly avoid it (anything that smells that bad can't be good to put on my food). So I decided to sacrifice some of my precious home brewed beer and set out slug traps. A little plastic pottle with a couple of centimetres of beer in the bottom and dig it into the ground a bit to give the slugs easy access. On my first attempt with only 1 trap, I caught 9 slugs and the second night I caught 12. Inspired by this, last night I put three pottles around my square foot garden. And the result? Three slugs! Oh well, I suppose the hard part was having to drink the remaining beer each night as the sun was going down.
