Rod Crouch's Profile

I visited a local rum shop in Barbados, and noticed that there was several clear plastic bags hanging from the ceiling three quarters filled with water, I asked what they where for, and he said it keeps flies at bay, I visited on several occasions, and sure enough I saw no flies, well I am 74 years old and very skeptical, but at home I have a window where flies accumulate, I use fly spray but they keep coming back, so I decided to give it a try, I got a Clear food and Bread storage bag 10in x 14in filled it 3/4 with water, and hung it level the top of the window, it has been there a week now and the flies have disappeared, do not ask me how it works I have not a clue. The man said to change the bag every 10 to 12 days.
