I can HEAR THEM!! Found mouse poo in my flat for a few days and saw a beast, so blocked holes, bought traps (but didn't use them in the end) and they seem to have gone. The neighbour in the studio upstairs is a bit boaksome and has rubbish bags piled up on her balcony, so am taking it she isn't TOO bothered about food/rat/mouse hygiene). She is always out in the evenings, and I can hear quite large sounding scurryings on the ceiling and it is freaking me out!! I don't want them back again!!
. It just feels uber gross as they are studio flats, so these creatures are less than 2 meters from my bed!
