do you eat candy often? Or maybe something else that is sweet? Flies smell even the most unnoticable smells. At least so i think.
There is this fly in the house and it always comes by me! (not that I'm smelly or anything) Why?
Are you wearing perfume, or hair spray? Sometimes they can attract insects. I quit wearing them because they attracted bees and I had some severe reactions to the last few stings.
