What is the white pine weevil?
The white pine weevil is considered one of the most destructive tree pests in the U.S. It primarily feeds on the white pine but has been known to favor a few other species such as the spruce and fir. This insect is extremely small in size, averaging at 7mm in its adult cycle. They tend to gather in the leaf debris at the base of your trees in winter, to emerge in spring and attack its hosts. The damage from a white pine weevil is extensive and can escalate extremely fast. If you suspect white pine weevils on your trees, it’s important to get a tree care estimate by a certified arborist immediately.

How do I get rid of the white pine weevil?
Unfortunately we cannot recommend any at home treatment for this pest, as it is so destructive and must be maintained properly. An application of insecticide should be applied by a tree care specialist between March and April when drops of resin are first detected. Depending on the extent of the damage, the remaining infected portions of branches should be removed and burned to prevent further outbreak.
We recommend a regular tree health inspection by an ISA certified arborist to prevent pests and decay from taking over. Click the link below to set up a free estimate with one of our arborists and start your tree pest prevention plan today!
