5.0 out of 5 stars Demolishes Two-spot Spider Mites
By Sudoku Caulton on June 3, 2018
My baby apple tree (grown indoors from seed) was infested for almost two years by two-spot spider mites (which I identified by magnifying glass and found they are a common scourge among apple trees.) I tried hand washing each leaf.I tried fumigation the whole thing with sage smoke. I tried the Three-Ways Organic pesticide. I had gotten so obsessed I was scanning leaves with the magnifying glass DAILY and almost always could find a couple, or the eggs, and I was spraying twice a week.

A garden pest site said the best approach is 1% horticultural oil spray, and I bought this one. Sprayed it heavily, just ONCE about 5 weeks ago. Not a single bug since. Not one. A few leaves (which I had left dripping with spray) did go brown on the edges. But the tree shot up at least 6 inches since I sprayed it. I still check a leaf or two once or twice a week. But clearly this spray kills the spider mites AND THEIR EGGS. So grateful ; ).
