During this project we contact HEPA vacuumed one air handling unit, all of the ductwork and all the floor registers/grills servicing the 1st floor office space/lobby at the 530 Old Whitfield Street building. There was dead mouse smell in the building that was causing unpleasant odors throughout the floor. After cleaning, fog ductwork with Envirocon (Fungistat, Bacteriostat, Deodorizer).
