A lot of people hang water bags over their doors to keep bugs away.

I do not know about you, but I feel like the bugs get worse every summer. Even better, don’t go outside after dinner, because that’s when the bugs seem to multiply and start making plans for how to attack.

But you shouldn’t have to worry about being outside because of annoying bugs. If you want to keep bugs out of your house, try this really simple and cheap hack from Newsner.

For this easy project, you’ll need these things:

freezer bag that is strong
A pinch of salt, a splash of lime juice, a few coins, and water
First, put everything else on the list into the freezer bag. Once the bag is sealed, hang it above your door or somewhere else near your house where bugs like to hang out. No matter where you hang the bag, make sure it gets a lot of sun. Lights inside your home will also work if you want to hang the bag somewhere.

To answer your question about how hanging a bag with water in it could possibly keep flies away, here it is. The bugs get lost when the water and coins reflect back into their eyes. They find it hard to see and fly, so they quickly learn to stay away from the area where the bag is hanging. One of the best things about this hack is that it doesn’t use any chemicals or bug-killers.
