Christim from Jackson, Mi writes
I have 42 5-year-old Norway Spruce trees. Eight trees have been hit by the pine weevil. I plan on treating them with this systemic. Is it recommended that I also treat the remaining trees, or hold off until I see evidence of infestation?
Applying a systemic insecticide such as Bio Advanced 12 Month Tree & Shrub Insect Control Landscape Formula prior to any signs of insects or damage is recommended to get ahead of any future infestations. This product is applied once a year and protects from the roots up throughout the trunk, branches, limbs and foliage. Please view the product label for more information.
