“Get Rid of Fruitflies with a Homemade Fruit Fly Trap. Pour just enough cider vinegar to cover the bottom of the jar. Add a drop of dish soap (it will break the surface tension of the vinegar so the fruit flies can't just sit atop the liquid). Now, cover the jar with plastic wrap and poke a few holes in the top.”
