Have a small infestation of houseflies in your home? Avoid chemical sprays, and pour them a glass of wine instead. Flies are attracted to the sweet smell of wine, so keep about 1/2 cup of red wine in a bottle and place it where flies are frequently seen. Add a little dish soap and water inside the wine bottle. When flies enter the bottle, the dish soap will coat their wings and make it impossible for them to escape. You can also pour the soapy wine mixture into a bowl and cover it with plastic wrap; poke a few holes so they can enter but not escape.
