Years ago after a visit here I arrived back at my house in Turkey and an excited neighbour was telling me how he had seen a big mouse on my roof .
I had no idea of what he was waffling about until I went inside the rat had bit through a 100 gallon water pipe to a tank sat on the roof that in turn the water sat on top of the concrete ceiling for 6 weeks covering everything in my bedroom in black mould a sight I will never forget.
Advice here is get it out at any costπ€
