A possum died wks ago in the crawl space below the house there are active white maggots in the vent how long before the awful smell goes away?

Answer 1

The smell from a decomposing possum can linger for several weeks, especially if maggots are present, as they indicate the body is still breaking down. Once the body is completely decomposed and the maggots have emerged as flies, the odor should gradually dissipate. To speed up the process, it's essential to remove any remnants of the carcass and clean the area thoroughly. After cleanup, using odor neutralizers can help eliminate any remaining smells.
