Tree Spraying

Treating trees and shrubs for pests is a necessary service that Woodchuck Tree Service provides. The method of application depends on the time of year and the surroundings. We offer high pressure tree spraying for a number of pests. We do systemic pesticide applications to the trunk or root zone and also injections to the trunk.

Pine Needle Scale

Pine Needle Scale affects pine and spruce trees. Needles appear discolored and begin dropping. Scales look like very small, white, sesame seed shaped insects. During winter, eggs incubate under mature females. Spraying is best done in the spring when the eggs hatch and the larvae are in the crawler stage.

White Pine Weevils

White Pine Weevils attack the tops of spruce trees. Insects hatch from the soil in the spring and feed on the top portion of the tree. Spraying should be done to the tops of the trees in the spring or fall.


Aphids can be on many species of trees, but do not usually cause any problems. Aphids feed on sap from the leaves. They produce a sticky substance called honey dew, which can coat anything and everything below the tree.

Cooley Gall Aphids

Cooley Gall Aphids form galls on spruce trees that often look like cones. Infestations can be very devastating, stunting growth and damaging branch tips. Spraying should be done in early spring or in the fall after the eggs have been laid.

Bark Beetles

Mountain Pine, Douglas Fir, and Spruce Bark Beetles destroy the cambium, and can kill trees in one year. Spruce and Mountain Pine Beetles fly August through October. Douglas Fir Beetles fly about June 1. Preventive spraying must be done before the beetles fly to keep healthy trees protected. Infected trees show globs of pitch on the trunk of trees and needles will yellow of the following spring. A good coat of insecticide once a year to the trunk will create barrier to infestation.

Aspen Diseases & Insects

Aspen trees can be victims of several diseases and insects. Two to three applications of preventative spray will help control leaf fungus.

In his final years of bike racing, Dan purchased a truck and chipper and started Woodchuck Tree Service, LLC, in 2010.
