Since Christmas I've heard loud scrabbling at night over our bedroom. DH thought it may have been a bird. I didn't and convinced him to put a mouse and rat trap up there. Today while near the loft, whatever is up there loudly banged/scrabbled/trampled over the loft hatch. DH came hoe and checked the traps. Both have been set off and emptied of chocolate (no jokes about the Easter bunny being up there please) and I'm thinking that there has to be something pretty huge up there to set off a rat trap and not get caught in it. Should I get the exterminators in or is that a no brainer...
