Earth Care’s Odor Remover Bag uses a natural earth mineral that is mined and processed to attract and remove all types of odor and smoke molecules. It is ideal for removing dead rodent odor and works even if the dead carcass is not removed. Its content is bio-degradable, non-flammable, non-toxic, safe around children, pets, and mother earth. It is easy to use, lasts an average of 3-4 months and contains no chemicals, toxins or fragrances. Earth Care does not mask odors, it removes them. Earth Care’s Odor Remover Bag can take from one hour to several days, but it is more effective since it removes odors versus masking them and is very simple to use and cost effective.
