Long story short, my flat has been taken over by mice in the past week. I live in a top flat of a 3 story building. It hasn't been an uncommon occurance at this time of year (over the past few years)
However, this year seems to be particularly bad. I've tried to cover up as many gaps as possible and put traps down, but over the past week there hasn't been one night where I haven't seen one. At one point they were running over my sofa.
I've never been scared of them, but since last week my anxiety has been through the roof. I can't relax in my own home 
Does anyone have any advice on what to do? Or how to get rid of them?
