My mother knew the benefits of using natural products like Olive Oil, long before I did. So, when my rose bushes recently started showing signs of the pesky nasty scale insects. I decided to use a remedy my Mother had told me about.
First, I grab a new .99 cent spray bottle from the Dollar store and filed it with about one third the way with good old fashion Olive Oil and the rest with distilled water. I than proceeded to spray my rose bushes and woola! The pesky bugs were gone.
