A simple and inexpensive trick may help keep your home and barbecues fly-free this summer. Some, however, remain skeptical.
AWM says to essentially fill a handful of ingredients into a bag of water and nail it above the door.
First, the site explains, one must gather together a plastic sandwich bag, some lime juice, table salt, a few pennies, and water.
After adding about 2.5 cups of waters into a bowl, one must stir and mix together a large amount of the lime juice and salt before pouring the contents into the bag.
Just before sealing it shut, add a few of the pennies.
One can either hang it on the doors or hang it from the barbecue using a bent-up paperclip. Just be sure, the site warns, that no water can escape the bag.
“Here’s the reason behind the effectiveness of homemade repellents. Flies have visual receptors called ommatidia,” one user said. “Unlike humans, they don’t have pupils that controls the amount of light that enters their eyes. Our pupils do, their ommatidium do not. Therefore, the reflective light or flickering light “scares” them because they can’t focus.”
The user explains another light trick one can use is spinning an old CD.
“The spinning CD that reflects the sunlight is a knockout for those pesky flies!!! Trust me…it works,” the individual said, while other users added that this trick indeed worked for them.
“I’ve seen a few flies,” waiter and stand-up comedian Shan “Aladdin” Ahmad, who used a similar trick, said of his restaurant, reports NOLA, “but compared to last year it’s almost 100 percent effective.”
But there are non-believers, like bug expert Zack Lemann, as well as the website TruthOrFiction.org.
Lemann explains when he experimented with the technique and found it to be a failure, while Truth Or Fiction added, “The claim that flies have poor eyesight is false. Their eyes are made up of thousands of individual lenses that can see polarized light and color spectrums that human eyes can’t.”
Meanwhile, they say, the popular TV show “Mythbusters” also tested it in 2010 and found it did not work.
