I HATE flies! How can I get rid of the flies in my bathroom?

This is going to sound crazy, but try it anyway--I was amazed that this worked.. Get 2 ziploc bags and some pennies. fill the bag up with water and pennies and tape them to the window and the mirror in the bathroom. This keeps flies from coming in. To get them out, I would try lavender oil and spray it everywhere, but especially along the baseboards and any cracks. Basil and bay leaves also work well. The cleaner its kept, the less flies. Also, try moving the trashcan out for a few weeks, or tying the bag in the trashcan up everytime its used. Hope this helps.
