Scratching Sound in Wall behind Refrigerator
Started hearing scratching/tapping noises in the wall behind the refrigerator about a month ago. We have a crawlspace so I am wondering if that has enabled some vermin to get into the walls. I have not seen any droppings or evidence of infestation just the random scratching sound, seems to happen at night before bed and around noon or so during the day when things are quiet.
Could this be mice? Is the humming of the fridge attracting them? I want to call an exterminator but at the same time I don't want to spend $200 being told what I suspect. I also shudder to think that I would have to have someone come in and smash drywall to get to the mice and then have to pay money to replace/repair the damage. This home is newly constructed for the most part, just the foundation, siding and one room are in the same shape prior to two years ago. The drywall, roof, studs, wiring, bathrooms, etc were all replaced.
