You can now take your water bottle and fill it up with just enough warm water to completely covers the banana slices and sugar.
Then, using a spoon, mix everything together thoroughly.
For the next step, you need to remove the cap from the top half of the bottle and flip it so it’s upside-down.
Then you should place it inside the bottom half of the bottle that contains the mixture, with the mouth facing downward.
Now that your contraption is built, you’re ready to catch some flies!
Just simply leave the device out in an open area of a room where flies are a problem and wait for the little pests to come to it.
If you’re wondering how the trap works, then let me explain.
The trap works by drawing the flies down through the opening of the bottle into the mixture in the bottom part. Once they’ve sated themselves down there, they struggle to get back out of the trap!
Your bottle will get pretty gross-looking after a couple of days, but leave it out for at least a week to maximize the amount of the insects you’re able to kill.
This trick is so simple, I’m surprised I hadn’t heard of it sooner!
It’s certainly a lot easier to have around than one of those sticky fly strips.
What do you think? Would you try this at home?
