We have spruce gall issues, and mites or some type of insect that takes out the tops of the spruce trees. Spruce gall seems to start in the fall, mites at the beginning of summer.
Bayer Advanced 12 Month Tree & Shrub Insect Control Landscape should only be applied once per year. We suggest consulting with your local cooperative extension office Master Gardener for alternate options.
