Hi Laura,
That is a kind of true bug (Order: Hemiptera). It looks like a
a scentless plant bug (Family: Rhopalidae), a seed bug (Family: Lygaeidae) or a seed bug relative (Superfamily: Lygaeoidea). I can't see enough details in your photo to ID the bug more specifically, but if you have specimens, I could take a look at them and tell you more.
If you want to send in specimens, they can be sent to me at the OSU Plant Clinic.

Meanwhile, scentless plant bugs and seed bugs are typically only nuisance pests when they get indoors. They don't bite or cause damage to structures or possession.
Here are some tips for controlling nuisance boxelder bugs from the PNW Insect Management Handbook. These may also help in your situation...
Inside homes, insecticides have limited value and are not recommended. Use a vacuum cleaner to pick up bugs in building interiors. Prevent bug entry by repairing screens and caulking around windows and doors, screen soffit, corner trim and attic vents, etc. Sealing is best done during the summer months when the bugs are not present.
Outdoor insecticide treatment has not been very successful. Residual sprays (by a pest control operator) where bugs congregate on building sides and near the foundation may reduce entry indoors but will not eliminate the insects.
