Start scouting for spruce spider mites

Growers
will want to begin scouting again for spruce spider mites. Spruce
spider mite is a “cool season mite,” and we sometimes see populations
build in the fall of the year. Pay particular attention to Fraser and
spruce trees you plan to harvest this year.
Check for mite activity by closely inspecting the older needles near the
tree stem or by sharply rapping shoots over white cardboard or a
notebook with white paper.
