How To Make A Homemade Fly Trap – DIY Guide

Is there anything more annoying than the common house fly?

It’s not that they do any major harm, but you’ll end up chasing that thing around for days trying to swat it with a rolled up newspaper, only to be a bit slow and just startle everyone in the house instead.

Trust me, I’ve been there.

The good news is, there is an easier way to get rid of the house fly.

Here is a great tutorial I found on how to make a homemade fly trap, using things you probably have in your kitchen right now. To read more about flies and their tendencies, as well as some of the science behind this trap, check this out from UFL.

The steps below come from a video posted by Build.com on Youtube.

Step 1: Cut A Plastic Water Bottle Near The Top

You want to cut it completely off, but don’t throw either piece away – you’ll use both parts when assembling the trap.

Step 2: Flip the top of the bottle over, and insert into the larger part – top down.

Note: you should leave about 1 inch of space between the top of your water mixture and the top of the bottle, like so:

If the sugar water mix doesn’t do the trick, you could also try adding some yeast to the mix – which can make the trap even more appealing to flies. To see the entire process in action, check out the video below from Build.com via Youtube:
