Spruce Spider Mites

If infestations continue, spruce spider mites may kill tree branches and possibly lead to tree death. Save your trees from these pests with the following tips.

CHILL OUT

Spruce spider mites thrive during the cooler temperatures in spring and fall. They range in color from green to orange-red and attack more than 40 species of conifers, including:

• Arborvitae
• Fir
• Hemlock
• Juniper
• Spruce (specifically dwarf Alberta spruce)

AFRAID OF NEEDLES?

Spruce spider mites feed on the sap from tree needles. Flecking and yellowing may occur near the feeding sites. Intense feeding may cause browning and premature needle drop. Silk webbing and cast skins from previous molts may indicate increasing infestation.

SPRUCE UP

You can help to curb spruce spider mite populations in the fall and reduce the number of overwintering eggs. Appropriate treatments include miticides or dormant oil, specifically in the north. Contact your local, licensed Davey service professional to determine the best treatment for your trees and landscape.
