So I have mice, was just sitting in my kitchen and saw one run over my coffee maker "shudder". They've eaten 3 bags of poison so that clearly doesn't work! I've tried all kinds of traps, nothing. We live in a terraced Victorian in London, so it's difficult to find/plug all the holes and they seem to be rife round here. The only thing I haven't used is the sticky traps, but they horrify me. They seem so cruel and I'd then have to kill them all myself. I contacted the council and they do 3 visits with poison for £130. Has anyone used a professional? Do they use stronger poison? If it would get rid of them I'd do it, but don't want to throw away £130 on the same poison I've been using! Any other tips? I keep the kitchen clean, no food left out for them to eat. All the usual stuff.
