So I emailed the suppliers and received a prompt reply:
Hi Geoff,
The slugs will have eaten them - all I can say is that you must have a large amount of slugs. They do eat them and go away and die. Any other animal should not eat them. Maybe you need to put more down next time and monitor it.

So I responded:
Thanks for the prompt reply.
You jest!
That sounds a very commercial answer but I shall put some more down and let you know.
