Q: I was reading up on controlling the leaf-footed plant bugs on my pistachio and almond trees and came across a recommendation by the University of California to use a pesticide containing bifenthrin. I see some Ortho products for lawn and garden contain bifenthrin. Is this a pyrethrin or something similar like you are recommending? Could this be used to spray the almond and pistachio every two to three weeks until it gets hot?
