Fly repellent - pinner said "I had to repin this again for you to see. YES IT WORKS! Oh my, it looks hokie but our temps have been upper 90's and no flies in my back yard have been spotted. I spoke with a women who grew up on a dairy farm and she swears by it. She said they used 5 pennies. Go figure."
Keep this in mind if you start seeing lots of spiders around your place. Natural spider killer or preventer... take one cup of vingar, one cup of pepper, a teaspoon of oil and liquid soap. Put it into a spray bottle and spray along the outside of your outside door and along windows; refresh after it rains.
