Materials Needed:
ball jar,or any empty glass jar
apple cider vinegar
rubber bands
aluminum foil


Put about 1/2 inch of apple cider vinegar in jar.With foil make a cone shape big enough to fit in jar with enough to wrap around top of jar.(the cone tip should be about 1/2 inch above vinegar) Wrap top of foil around jar with rubber bands to hold in place.Place jar nearest to fly problem area.......The fly's will enter,drink the vinegar,become gorged and drown,unable to fly out of the opening they came in....presto no more fly prob!

I do something similar. I use apple cider vinegar in a cup with a drop of dishwash soap in it to remove the surface tension of the vinegar. I cover the top of the cup with plastic wrap and pop a few holes in it.

Flies are usually gone within a day or two.

You can also use a mixture of 2 parts corn syrup, 1 part sugar. Mix it, soak strips of a brown paper bag overnight. hang over a bowl(to catch the drippings). Maple sryup and brown sugar...umm I guess anything sweet and sticky. Molasses or honey would make a good fly paper too. I've also read that flies don't like pine, so pine sap would be a no-go.
