Western Conifer Seed Bug

Found in coniferous forests and surrounding residential areas throughout North America and Europe.

Feeds primarily on the sap of developing cones on evergreen trees like pines, Douglas firs, and spruce.

They are active during warmer months and seek shelter in houses and buildings during late autumn to overwinter. They produce a distinct buzzing sound when flying and a foul odor if threatened.

They are nuisance pests in homes but do not bite, sting, or cause structural damage. In forests, they can impact seed production, which can be a concern for tree nurseries.
