I have some animals in my loft, I can hear them scratching around up there. A month ago it was once a day in the night-time, but now I can hear the noise a few times a day and a few times in the night. I've been up inside the loft and I can't see anything up there at all, no nest or droppings or anything.
Here's a picture of the inside of the loft, around the area where I hear the scratching most often. I've lifted up the insulation and I can't see anything under it either. There's loads of spaces where the animals might be getting in from one of the neighbouring houses. Why do animals even want to be in my loft if they're not making some kind of a nest up there?
I made a recording of the scratching noise that I'm hearing. Does anybody know what animal this noise is likely to be? I guess maybe pigeons or rats? I live in a terraced house in the north of England.
My landlord's response is that he can't see anything, therefore there's probably no animals. Is there anything I can say to him, apart from showing him the recording, to encourage him to do something about it? Is there any other way for me to find any additional evidence about the animals? Maybe there's something I can see if I look more carefully in the loft?
