I live in a flat above a shop and have mentioned to my landlord on more than one occasion that there are mice in the flat and that I have been trying to get rid of them. He hasn't even acknowledged the problem, let alone offer to help. I've bought various traps and have caught a couple, but I think prevention is the better solution. I need to stop them getting in in the first place. Has anyone been in this position before? I just want them out. Finding their droppings everywhere is grim and I feel like I am constantly cleaning.
