Although on the funny side, I did, on my neighbours behalf call in the
local ratman, to sort out the compost heaps and he left his little
plastic trays full of poison and the rats ate them, the trays that is.
The poison was goe in hours, and the trays about a day later, though
no bodies turned up anywhere !!!

My Ratman left his poisoned grain under the shed in a transparent plastic
bag.

"It will gnaw through it" he said "And that will be the end of it"

The bag was not touched days later when he came and took it away - though
my rat did move out, presumably having taken the hint.

It was a hell of a rat too - about the size of my rabbits (and they are
quite chubby).
