Killed two in traps (the sprung "splat" variety) baited with a large
pile of poison:

But we have a third - it just eats all the poison - and the trap does
not go off ! It's really strange - done that four times now, so I guess
it's very sick..

No need for expensive poison - just good bait. I have used rasins or prunes
in the past.

You need to TIE the bait to the release arm with a bit of wire, if you don't,
they can nibble it away without springing it, so use tiable bait, not a
paste.
