3.0 out of 5 stars Better for smaller trees, January 7, 2009

We bought this spray to treat gall mites on our Silver Maple trees. It worked to reduce the number of mites but didn't completely cure it. In order for it to work you have to pretty much saturate the entire trunk and branches. From what I've read, the oil suffocates the mites so they can't come out and settle on the leaves where they reproduce. You have to spray the entire tree in the Fall after the leaves fall off and in the Spring before the tree buds. If you have a larger tree, this might not be possible.

I spray it (diluted) on cucumber plants to treat spider mites and on orange trees to treat scales. It worked OK on the scales, but I am not sure it did anything to the spider mites. Those little red critters are every where now, on cucumbers and string beans. I am still trying to find an "organic way" to treat them.
