Western Conifer Seed Bug

Found in coniferous forests and around residential areas where pine, Douglas-fir, and cedar trees are present; commonly seeks shelter indoors during cold months.

Feeds on the developing seeds and cones of coniferous trees by piercing them with a needle-like proboscis and sucking out the nutrients.

They are active flyers and are often found basking in the sun; in late autumn, they aggregate on the walls of buildings to find crevices for overwintering.

They do not bite, sting, or carry diseases, and they do not cause structural damage to homes. They are considered a nuisance pest indoors due to a faint pungent odor they release when threatened. In the ecosystem, they can reduce the seed yield of timber trees.
