My Grandma’s Fruit Fly Trap Works Every Time and Costs Basically Nothing

How to Make a DIY Fruit Fly Trap with Apple Cider Vinegar

To create a easy, low-cost fruit fly trap, you’ll need a jar or bottle, some dish soap, apple cider vinegar, and plastic wrap. To make the trap, you’ll add apple cider vinegar and dish soap to a jar, wrap plastic wrap tightly around the top, and poke a few holes. The fruit flies will be attracted to the apple cider vinegar and get trapped inside the jar.
