Dead branches? Strange holes? It might be bronze birch borer! 🪲

The bronze birch borer (Agrilus anxius) is a native pest to North America. This insect is found in southern Canada
and the northern United States and is a serious pest of native white or paper birch and the European white birch.
Bronze birch borer attacks are more frequent on ornamental birches planted in the urban environment than native
birches growing in natural forests.

Healthy, vigorous birches are most resistant to bronze
birch borer attack. Good tree vitality can be
accomplished through fertilization according to soil
test reports, irrigation during dry periods, proper
pruning, and appropriate mulching of the root zone.
Pruning should occur when early dieback symptoms
are evident in the upper crown. Fall pruning is
encouraged since it limits fresh wounds and sap
bleeding that may attract adult borers. Preventative
and therapeutic chemical treatments may be applied in
areas that have a history of bronze birch borer activity.
Contact a Bartlett Arborist Representative to
learn about control options for this pest.

That's not snow, it's Cooley Spruce Adelgid! 🐛

The feeding activity of this arthropod pest can result in severe damage to ornamental trees and may also cause the formation of cone-like galls on developing twigs, which can hinder growth and predispose the tree to further infestations from other pests or diseases.

Galls from this insect will be one 1-3" long, occurring primarily at the tip of the twig. The Cooley Spruce Adelgid primarily targets Blue, Engelmann, and Sitka Spruce as well as Douglas Fir trees.

offers a highly successful treatment program to control Cooley Spruce Adelgid and keep your trees healthy 🌲😄
