Hi all. Truly Nolan is coming to deal with mouse infestation in my attic. According to my husband, they don't clean up the droppings. It's a drywall ceiling so he's planning on putting boards up there to crawl around and just spraying bleach or tea tree oil on it all and leaving it there. Can that work? Doesn't sound good to me. Do any of you know someone who knows what they are doing and can remove the droppings for us? Thank you all
