What bug borers in your Blue Spruce tree?

The primary pest that bores into Blue Spruce trees is the spruce engraver beetle (Scolytus spp.), which can cause significant damage by tunneling into the tree's bark. Additionally, the Douglas-fir beetle (Dendroctonus pseudotsugae) can also affect spruce trees. These beetles create galleries under the bark, disrupting the flow of nutrients and potentially leading to tree decline or death. Regular monitoring and management practices are essential to protect Blue Spruce trees from these pests.
