We've had a minor mouse problem twice in the past 18 months. The first time, we paid for the council service. It had zero effect and as far as I know the specialist poisons they put down went untouched until they took them away.The most we got out of it was a bit of information:1) Mice are neophobic (afraid of change). I've read advice somewhere that you should move your traps about so the rodents don’t learn where they are. Apparently this is not true at all, as they are far more likely to avoid a new thing than one they're familiar with. When laying traps or poison, expect them to go untouched for a few days at least.2) Wire wool. It's been said already, but this is really the ONLY thing that helped us. I once caught a mouse in a trap, but it had no effect on the minor infestation. Crawling around the flat with a bag of wire wool and a screwdriver to jam it into EVERY tiny hole or gap anywhere near the floor finally got rid of them. As Mark said - mice don't just live in your place, they move beneath and up and down buildings as they can and your neighbours may or may not be taking action against them.Our mice were coming up from the estate agents office we live above, via holes around the internal plumbing, and into our kitchen through a gap under a work surface. Once we worked that out, lots of wire wool (and some gaffer tape) made it difficult enough for them that they went elsewhere. To make sure, I stuffed every tiny hole everywhere I could find in the flat, so they couldn't find an alternative route in.Also check for what I think are called "air bricks" around the outside of the building. If any of them are accessible to mice, place a fine wire mesh over them to prevent access, while retaining the important ventilation.If you actually have rats rather than mice...not sure what to advise. Rats are another thing altogether, I think you'd need to call in the professionals.
