I have a old sago palm and for years its had Milly bugs all over it and that may not be the correct name but it's the white fuzzy cotton looking insect,it's been coming back every year and we been fighting that insect four years it's hard to kill with that rough trunk on the Sago. They just bury down in there,but this year it has no new growth,how can I tell if it's dead,and will those insect eventually kill something that big if they get ahead of us treating them.
