I have red and black bugs outside my back door. They are also getting into the house the adult ones can fly; the babies are all red.

Are they a bright red with black. Do they sort of bunch up or huddle together? could be Japanese beetles.
If a dull black/brown with red, they might be box elder bugs which are a nuisance but don't bite.
