Lower level of tri-level is musty smelling
I have a tri-level house but the lower level isn't used very much because it smells musty and has spiders and other creepy bugs. The area is separated by a small 3' high wood door. The smaller side is the crawl space with a sand floor. It smells musty but looks and feels pretty dry. The larger area has a linoleum floor and part of it is walled off where the laundry area and a 2nd bathroom are. There are no leaks, drips or anything. Currently I just use it for storage and doing laundry. What can I do to make this area smell better and more livable?
As I write, I'm in the process of setting off a bug fogger. Then I'm going to scrub the floors and set up a dehumidifier (it's just a mini one). Will this be enough? Anything other suggestions?
About the wood door separating the crawl space: it fits pretty snugly, but is there more I can do to seal it from the main section? I don't know if all tri-levels have this little door so hopefully you know what I'm talking about. I can post a pic if needed.
