cat poop problem
My wife and I moved into an older house about a year ago, and had been dealing with a cat dropping odor we couldn't get rid of (we don't even have any pets). It was especially bad when it rained or was damp out.
Looks like I found the problem, but I don't know how to take care of it. The house was neglected for several years, and the previous owner apparently let the crawl space door hang open. The neighborhood is full of feral cats, and apparently, the crawl space was their "litter box" I discovered this when I was down there fixing some plumbing issues about a month or so ago. When we looked at the house during the summer, I got under there with the home inspector, and neither one of us caught this because it was dry out and had not rained in several weeks (the foundation vents were open too). The stench however was so bad this time I could not even go down there.
I am thinking I might need to wait till summer, but what will need to be done here? I am thinking an arduous task of excavating about 6 inches of all the dirt in the crawl space is going to be the only way to take care of this. Any other better or easier ideas?
