Sometimes down-home wisdom is just the best.
Reports from the country here in America claim that the best and least toxic way to keep flies away is to put a few pennies in a Ziploc bag, fill it with water and somehow lash the thing to the supports for a porch roof or opening to a house. (This method has not been proven successful in the open air.) For some reason, and no one is quite sure why the common housefly (moscono in Italian) will simply not venture where one of these baggies is.
This morning I checked this simple idea out on Google.
Below are comments on this fly control idea. I’m now a believer!
Zip-lock Water Bags:
#1 Says: I tried the zip lock bag and pennies this weekend. I have a horse trailer. The flies were bad while I was camping. I put the baggies with pennies above the door. NOT ONE FLY came in the trailer. The horse trailer part had many? Not sure why it works but it does!
#2 Says: Fill a zip lock bag with water and 5 or 6 pennies and hang it in the problem area. In my case it was a particular window in my home. It had a slight passage way for insects. Ever since I have done that, it has kept flies and wasps away. Some say that wasps and flies mistake the bag for some other insect nest and are threatened.
#3 Says: I swear by the plastic bag of water trick. I have them on porch and basement. We saw these in Northeast Mo. at an Amish grocery store & have used them since. They say it works because a fly sees a reflection & won’t come around.
This way of doing things has been tested on Mythbusters and other places. They did not have success. But, they also were not experimenting with a structure with a roof. One friend who says the trick really does work, confirms that these baggies are always attached to a structure with a roof.
So, for those who have a fly problem in a house or under a porch roof, there might well be the non-toxic cost-effective way of dealing with them
