How to Get Rid of Fruit Flys

For ABSOLUTELY no reason there are sooo many fruit flies in my house.  To get rid of them I have found an easy, safe, and non-chemical way to get rid of them.   In a short glass, put a couple ounces of apple cider vinegar, and a bit of dish soap.  Then swirl it around so the dish soap dissolves. Set it  out, and the flies will come to drink up the cider, but their wings will cause bubbles to form.  Then the drown. And that's how you get rid of fruit flies!
