So your mother-in-law is due for a visit over the holidays. Upon her arrival you can see it on her face, as she then says what's that smell? Suddenly your horrified. Your house smells of a lingering odor.

Well lets start at the obvious. Do you have any pets be it either cats or dogs. If so that's probably your first guess. It may not even be something as simple as urine or poop, often time pet dander is what can dwell in your carpet with out even being noticeable. If it is urine you may have just a small spot or two? One thing you can do that can be more revealing is using a black light to see whats being in your carpets. You can hire the services of TLC Carpet Care.
