As the title says really. We've had the same issue in the past, hence I had things in to try and help.
Realised when I got home that there was a rat in the kitchen. Opened the back door and made a lot of noise, then left the door open for a while so it could get out. Couldn't hear it anymore, so shut the door, found a hole where it must have come in. Tipped peppermint pellets into the gap and stuffed it with wire wool. Went and did some other stuff and then went back to the kitchen. The bloody thing has pulled the wire wool out and is back in the kitchen.
Ugggh. I don't know what to do. Landlord refuses to do anything about it, can't afford to move.
Does anyone have any tried and tested methods? Or do I need to call in pest control? Is that expensive? I am unbelievably skint right now.
