Western Conifer Seed Bug

Found primarily in coniferous forests, but often seeks shelter inside buildings or under bark during the winter.

Feeds on the developing seeds and cones of various coniferous trees (such as Douglas fir, pine, and spruce) using piercing-sucking mouthparts.

Nymphs and adults feed on tree seeds throughout summer. In autumn, adults frequently aggregate on south-facing walls and enter homes to hibernate. They are capable of flight and produce a loud buzzing sound.

Harmless to humans as they do not bite or sting, and they do not cause structural damage to homes. However, they can produce a pungent odor if threatened or crushed. They are considered minor forest pests due to reducing seed yields.
