When you have food out in the open, you’ll probably have fruit flies buzzing around as well. Researchers have found a quick way to trap these pesky pests in one place so you can release them far away later.
Here’s what you have to do:
- In a small jar, pour cider vinegar about two centimeters deep.
- “Cap” off the jar using a plastic funnel or even a makeshift one from paper.
- Tape the funnel to the jar’s opening so no flies can escape.
Flies are attracted to the smell of rotting or aging fruit. They use their sense of smell to find the source of the odor. They are attracted to things like acetic acid, which is a molecule found in vinegar and the source of its pungent smell.
The vinegar inside the jar will lure them inside the trap while the funnel lets them in without any chances of them getting out. Just remember to replace the vinegar every two days.
Fruit flies are originally an African species that gradually spread across the globe. They are called a “cosmopolitan” species because they are found wherever people are.
What is your reaction?
