The spruce budworm is a small brown moth which lays its eggs on balsam fir, white spruce and sometimes red and black spruce. Newly hatched larvae make nests in protected areas where they overwinter. Feeding commences in the spring with defoliation becoming apparent later in the summer.
DAMAGE
The caterpillars feed on the needles of spruce and fir trees and in great numbers can cause serious defoliation and in cases of large outbreaks, result in wide scale tree mortality.
There are specific solutions for different species of moths.
