Apologies to far more attractive Jennifer Garner for borrowing a piece of her credit card commercial pitch, but seriously if Moldy Mike the Fungi needs to dress up like this to crawl under your house (he must), and if up to 50% of the air in your house at any given time was once in your crawl space (it was), then shouldn't it make sense for you to be fully aware of what's happening down there???!!! (it does)
For the love of family, health and home, please please please make sure you know the answer to this question!!!
