Western Conifer-Seed Bug
Western Conifer-Seed Bugs are an Ugly, Stinky – but Harmless – Nuisance.
The western conifer-seed bug (Leptoglossus occidentalis) is believed to be native to North America west of the Rocky Mountains. However, western conifer-seed bugs have been expanding eastward and were first found in Minnesota in the late 1980’s. Today, they extend all across the northern United States into Canada.
Western conifer-seed bugs generally become a nuisance pest in the fall, when they seek shelter before the coming winter. Much like boxelder bugs and lady beetles, western conifer-seed bugs enter structures through cracks and gaps.
If these fall pests become a nuisance around your structure, call Adam’s.
