I've had an orchard for four years. This year, the tent caterpillars have decided they are taking over. Can you tell me, besides using BT, what are some other ways to get rid of these pests? Should I have sprayed with BT earlier, like before they went into pink bud, or can I spray now that they are blooming? What would make them come in this year instead of last or the previous years?
