Soak any area that has been sprayed with Simple Solution or Nature's Miracle. Be sure to use a lot and hit every surface. Do not wipe up. Allow to dry. Repeat if needed. In extreme cases, try Bac-A-Zap from the exterminator supply store. Bac-A-Zap is used by pest control to eliminate the odor of dead animals so it works right away, while the other solutions take a couple of days to eliminate the smell.
