I've been hearing a ticking noise coming from a part of the loft (but only from a small area above one of the corners in a room). It sounds like a clock ticking very fast. It happens on and off all day and all night. I live in a bungalow next to fields used for sheep and cattle grazing. Have lived here for a long time and have had problems in the past with mice and squirrels getting into the loft but it's been pest-free for the last few years since various repairs were done. I'll have to call an exterminator eventually because I can't get up to the loft myself.
Has anyone come across anything similar? I've gone through YT videos listening to insect sounds and haven't found anything like it. Just can’t think what it could be...
