Oh! Thank you - I've got some mint essential oil so I'l try that. Or is it a special commercial spray that you can buy?
I have to admit I hate the thought of poisoning/killing anything - even a rat, so I'm putting off calling the Ratman just yet. Left to myself I'd catch it and release it into a forest somewhere, but I was told in n uncertain terms when we had our last rat (was talking to next-door neighbour - she says it was over 20 years ago because she can remember me warning her to take her kids plastic toys (slide etc) in overnight because of the risk of infection, and her oldest is 28 now.
I told DH that if I could I would catch it and let it live out its natural life in an outdoor wire rat-prison with a slide tray at the bottom so I could clean it out.
I'd be too wary to touch it, but I'd not object to dropping feed through the bars and giving it fresh water etc.
We were having a look at where it may have come in and think it might be a transient, just looking for somewhere to dine out and maybe rest its weary little verminous head for the night. TBH, with four dogs and 2 cats in the close vicinity (and that's just our house - other neighbours have more) I think it's unlikely to want to move in. The Ratman told us our other one was just a visitor (he Knew About These Things) and would leave after the winter anyway - but as I say, it got terriered.
Polecats eh? I'll bet they stink!
