Does hanging water in a plastic bag really repel houseflies? Here's what experts say
There's no doubt that house flies are a problem in every household no matter where you live. They can invade mostly kitchens, bedrooms, living rooms and other areas even when hygiene levels are up.
But while we think there’s just no way to stop the little flying things from entering our homes,there are some tricks and hacks that many claim can keep them away.
One popular trick, which almost everyone has seen, involves hanging a plastic bag of water in a housefly-affected area. We’ve seen it in shops, small eateries and even homes.
But does it actually work?
The surprising thing is that the hack is not just used by Indians and the people in the sub-continent during peak summer months. It happens to be a popular pest control trick in America as well, with the addition of something extra.
The addition involves adding some coins to the plastic bag before hanging it from a wall or door.
Supporters of this DIY trick claim zip-tops or ordinary plastic bags filled with water and some coins repel houseflies.
The science here is that the bags mess up the eyesight of a flies, which are made up of hundreds of individual lenses that are perceptive to changes in light. So, when the light hits the bag of water with coins, it refracts and confuses the flies. And that's why they fly away and go to some other area.
Supporters and testers of the trick certainly seem to think it works. Some have even theorised that the plastic bags fool a fly into believing the filled bags are another insect’s eye or surface water, causing them to fly elsewhere.
But experts are not convinced.
Scot Hodges, a fly expert, told Fox Digital: "I have visited properties that have had the penny-filled bags and flies, so my observation is that this is not something that can be relied on."
He added that the solution to the fly problem is good hygiene and proper sanitation.
He added: "Most flies feed on dead or decaying organic matter, which is what typically causes the flies to appear. From there, they lay their eggs in the food source and more flies hatch out and the cycle continues until the food source and breeding site is removed or corrected."
