Just finished reading Amy Grants article, Natural Pest Repellent: Do Hot Peppers Deter Pests In The Garden. In her article she mentions that research has indicated one variety of pepper was found useful against spider mites, but then fails to mention which one. Please give the reference citation to the original research article she was discussing and the specific variety of pepper that was mentioned for control. thank you.
Use Cayenne Peppers in this mixture.
