My sewage line came loose under my house. It was loose for awhile and now there is standing water under there house. I put a fan blowing on the water to gas it off but it stinks real bad. When the water is all gone what can I spray or put under the house to kill the smell. I thought I would mix clorox and water and spray it to kill any fungus. Would that also kill the smell?

Spread powered lime on thee surface area.

I wouldn't use any clorox though.

You should be pumping this out and not trying to evaporate it, its sewage. You should also hose it down and then spread lime like oneson says
