During the summer months, there's a high chance that your home is full of fruit flies. These things fly around your head, make a home on the food on your kitchen countertops, and breed like crazy. Before you know it, your whole house is infested, and there's nothing you can do about it... or so you thought. One grandma hack involves trapping fruit flies with a simple bowl of apple cider vinegar.
Ideally, you should mix two teaspoons of apple cider vinegar with three drops of dish soap and one tablespoon of water for it to be as effective as possible. Then, wait for the flies to fly into it.
