If you have fruit trees, you know what a pain it can be to keep the fruit bug free. Dormant oil spray is expensive, but often has to be used. Here is a homemade Dormant spray that doesn't contain oil of any kind, but it's effective:
A gallon of water
2 TBS baking soda
5 TBS hydrogen peroxide
2 TBS liquid castile soap (like Dr. Bronner's)
Mix it all together and spray your fruit trees or bushes after they've gone dormant this fall and again in the spring before they wake up.
