Repel Houseflies with Cloves and Clove OilS

If you prefer natural pest repellents in your home, the folks at The Kitchn explain that whole cloves, or even clove oil in homemade cleaning products, will keep flies at bay.

Apparently, flies hate the smell of cloves, and one way to keep them at bay when you're enjoying a backyard barbeque or just enjoying a breeze with the windows open is to hang whole cloves in a small square of cheesecloth or, as the WikiHow link below explains, decorate an apple with whole cloves studded into it and put that where the flies tend to hang around.

Since it's the smell of cloves that the flies don't like, we'd suggest taking the tip a step further and grinding them up, or using clove oil instead when you mix homemade cleaning products or even air fresheners—cloves smell great to people, but if flies hate it, it'll keep them away.
