A Simple DIY to Rid Your Outdoor Space of Flies.


No Sprays. No Chemicals.


No Bug-Zappers. No Swats.


Cheap to Do. Pennies. Really.


Just a Simple Hanging Bag of Water!

But Exactly How Do No-Fly Water Bags Work?


It’s All About REFRACTION and a FLY’S COMPLEX EYES…


Flies have a highly sensitive array of eyes which allow it to see in multiple directions at once. The insect’s head mostly consists of a pair of large complex eyes, each of which is composed of 3,000 to 6,000 simple eyes. These eyes can’t move or focus on objects like human eyes, but they provide the fly with a mosaic view of the world around them. A housefly bases its sense of direction on the direction sunlight comes from. Some entomologists believe that when these complex, sensitive eyes experience refracted light, the insect becomes confused and flies away.

Now that You Know How Water Bags Work…In Theory…Whip Up a Few Water Bags to Cover Your Outdoor Space to Have it be Fly-Free.


What You Need:


Quart Freezer Plastic Bags.  LINK.

Scissor.  

Fishing Line.  LINK.

Pennies.

First – Poke a Hole in the Top Thick Closure Section of the Bag. Gallon freezer bags are thick and work great.

Next, fill the bag 3/4 full with water.

Drop in 3 shiny pennies.

The pennies will SINK to the bottom of the bag.

Carefully zip the bag seal to close tightly.

Now bring the water bag outside.

Slip the fishing line into the top hole of the bag. Loop and make a strong knot.

Hang in areas with the most sunlight and where you want to be Fly Free.

The bag swinging gently works best to get the biggest reflection.

Now Sit Back and Enjoy Spring! Flies Be Gone! Fly Free!

    I tried this and it didn't work! I put 3 bags on the corners of my patio roof and I still had flies galore.

      Hi Pat. The bags only work if in sunlight. Perhaps that is the problem. The bags also need to hang freely and swing around to bounce and reflect the light. Hope this helps! Jeanne I'd Doodle T and Me!
