We have a serious odor problem within our house. We have a crawlspace with a dirt floor. We live in an area of town that is often standing in water with any amount of rain. I feel if we could find a solution to drying that space, it could possibly help with the odor. Any suggestions?

Drying would be the best start but you likely have mold already growing and this needs treatment. Spreading lime will help kill what you have but you must get rid of the moisture to really prevent a repeat of what you have.
