Get rid of Flies

My back door is always left open, which means I always have disgusting flies coming into my kitchen. I found this thing on Pinterest, that I though was a way to make women on Pinterest do something stupid,  but I was desperate and tried it. I filled a ziplock baggy with water, and added 4 penny's. I hung it above my stove. I have only seen 2 flies in my kitchen in the last MONTH!!! I can't believe this trick works. Since it worked so well for me I though I would share it with you.

Thank you PINTEREST!!!!!!
