Essential Oil Room Spray to get rid of pesky house flies naturally: "Lavender, eucalyptus, peppermint, and lemon grass essential oils can be mixed together to create a powerful fly-be-gone spray. Spraying this mixture all over your home will keep the flies from wanting to get in."
We noticed zip lock baggies pinned to a post and a wall. The bags were half filled with ...water, each contained 4 pennies, and they were zipped shut. Naturally we were curious! The owner told us that these baggies kept the flies away! So naturally we were even more curious! We actually watched some flies come in the open window, stand around on the window sill, and then fly out again. And there were no flies in the eating area!
