Smoke from a recent fire leaves particles and odor molecules that settle deep into drywall, carpet padding, upholstery, HVAC ducts and wood framing. Any remaining soot or damaged materials should be addressed first so the fogging step can focus on the embedded odors.

The space must be empty of people and pets during treatment and ventilated afterward. Heavy smoke odors in Java, SD may need more than one visit to reach full effect.
