Using dimethoate 4E on them this year. It has some systemic action as well. Other chems in replies will work too, but with 70 acres of Christmas Trees, it pays to rotate to a different chem now and then. The key is to get them when they are a quarter inch or less. Once that bag is fully developed, you need to use a biological insecticide. We use them every year as well. Dipel and Conserve are both good ones
