I think this product is for use in a closet, I intend to resume my other closets. It turns green in a fortnight and months so I plug to remove moisture overnight. by against has not remove the closet smell of mold, maybe with time. I did not dare leave the cupboards too open with moths (flying), but I just installed mosquito nets. this product is more environmentally friendly and economical than the bags that I have usually renewed every month.
