So it's a good thing that we found a simple and environmentally friendly trick that will help you get through the summer clean and free of flies.

Keep reading and see how to make the upcoming summer more pleasant.

You don't need much to make this homemade fly trap - in fact, you probably already have everything you need at home.

What you need:

• Heavy duty freezer bag (a large Ziploc bag will do)
• Table salt
• Lime juice
• Some coins
• Water

Put everything in the freezer bag and very quickly you will have a device that is the nightmare of every fly.

Fill the clear bag with water and hang it high outside your door.

Because you need a light source for this trick to work, the best thing to do is to hang the bag as close to the light you have outside as possible, so the flies stay away day and night.

Why do flies hate it so much?

Most insect repellants are based on different smells. This insect repellent is not based on smell, but rather it has to do with the way flies see the world.

Sparkling coins in the water create discomfort and a frightening appearance for the flies.

The flies have complex eyes and the coins in the water create an illusion for them and they don't want to approach the area.

What the flies see in the bag is a reflection of light, something the human eye can easily handle. But for a fly, it's a completely different story.

Let's take the common fly for example. These insects are born with a pair of huge eyes relative to their size. The eyes that consist of 3000-6000 lenses see the world in a mosaic pattern. Pretty cool, isn't it?

The coins in the water create a refraction of light that confuses them, forcing them to leave.

Now that you know this simple trick that flies hate, it's time to build your own trap. Enjoy a fly-free summer!

What do you think of the trick? Have you tried it before? Many who have built it have testified that it works great, so you should definitely give it a try.
