My sister shared a recipe for bug spray with me the other day that her SIL that owns a nursery shared with her. It WORKS!!!!
1/4 cup buttermilk
2 cups flour (either self rising or plain)
enough water to fill the rest of a gallon jug
Mix all this together and put in sprayer and spray your plants and bushes. We both have tried it out and it really works. You will see the difference!! Just shake it up real good so the flour doesn't settle to the bottom!!! I don't know if it kills the bugs or they just can't stand buttermilk. Try it!!
