What's That Bug? does not endorse extermination

what are these flying bugs?
Hi Bugman, you’ve got a great website! Can you tell me about the bugs that are in my yard by the thousands? They’re all over the Portland, OR area. They don’t seem to bite, but are terribly annoying. They’re about 3/4 inch long and when flying, a bright orange body is visible. Are they likely to leave soon?
Thanks for the info,
Bev

Hi Bev,
You have Western Box-elder Bugs, Boisea rubrolineata. It feeds on Box-elder, Ash and Maple. Adults and nymphs aggregate in huge numbers, and often get inside homes to hibernate. They are difficult to erradicate, and since you have mating activity, you are well assured of future generations.
