Caterpillars on my arborvitae shrubs
There are about 3-4 caterpillars per tree. They are brown with rust colored fuzz and some golden yellow in their "fuzz." Are these bagworms? I need to know how to get rid of them. I have 20 arborvitae (each 6 feet tall), planted 18 months ago here in Coos Bay, OR and they are doing really well up until now.....Please I can use any info you may have on this~ Thanks!
