Place a few cotton balls in the bottom of a glass jar. Add the vanilla extract and then the mint and basil leaves. Place a piece of cheesecloth on top. Place in places where flies are likely to enter, and they won’t venture in!
4. The Bag & Coin Trick
Fill a clear plastic bag with water and then a few pennies. Hang the bag in a place where flies can fly or near your outside doors. The reflection created by the water and the coins will scare the flies away.
5. Vodka & Cloves
Add some vodka, water, and cloves (or clove essential oil) to a spray bottle. Spray the solution on exterior doorways, window frames, etc. to keep pesky flies at bay.
Hopefully you can use these tips to keep flies outside, where they belong, all summer long. Good luck!
