I have a small collection of soaps & creams in my shave den. All of them are in screw top plastic tub containers stored in a wall mounted cabinet. I am a neat freakish, perfectionistic, clean freak and I am having a problem with fruit flies in the shave den this past month (not swarms, but I kill about 2 per day and am not having this problem anywhere else in the house). I am baffled by this as everything is sealed. Has anyone else had this issue and if so how did you correct? Do you think there is a collection of soap residue down the drain or something that is attracting them? Any advice is much appreciated.
