Hi Rae
Yes I have tried slug pubs. I think it just attracts them. Also my slugs seem to drown and not wander off to poison birds.
I thought that it was the slug pellets that poison birds. As I garden organically I do not use slug pellets.
I have even seen slugs climb up my broom plant to make the branches droop over on to my Hostas. And they say they have small brains. :?
Usually I plant twice as much in hope that the slugs will leave me some for being kind.
