Can I treat Pine Needle Scale, on my spruce tress in the fall or should it be done in the spring? I just found

it and want to do something right away.

Pine needle scale on spruce or pine is treated in the spring. You can either use a horticultural oil or a labeled insecticide when the crawlers are active. See the link below for a pamphlet on evergreen insects which has the needed information on what to apply and the timing for pine needle scale. Thank-you for using eXtension.
