The best thing to do here is to give me a call. In most cases I will be able to advise what the problem is; from rats in your loft space or something biting you, to whether that insistent noise you are hearing is from a wasps nest or just a smoke alarm with a flat battery.
Different types of rodent make different types of noise ad do birds walking over your roof or nesting in your soffit. As I do not charge for the initial visit I could diagnose your problem, give you a quote for a solution , and you will have lost nothing if you decide not to go ahead or if it turns out not to be a pest problem.
