We have mice. And I think the problem is escalating. We have put down a Rentokil child-safe poison (one where the poison is inside a little tunnel) but the mice don't seem to be taking the bait. We've also been leaving a snap-trap out at night, but again they're not taking the bait.
If we call in Rentokil or similar, will they do anything we couldn't do ourselves? Any advice? I'm starting to get quite worried about it!
