Q.Pests
Live in Winchester, VA. When do I begin to spray Bifen for bag worms? I can many see small bags on a thick and tall row of junipers. When do I start to spread Eco-bran for grasshoppers? I have many young deciduous trees…too tall and wide to cover. Will I likely lose them with the expected cicada brood to hit our area?
