European Hornets attracted to porch light

This insect shows up on our covered back porch above the door at night only after the porch light had been on for awhile. I never see them during the day. I believe they live behind the porch light. They are about 1 1/2 – 1 3/4 inches long. My wife thinks they are cicada killers, but I believe they might be scarab hunter wasps. They seem pretty docile and have never stung anyone. I do have a sting allergy and have some reservations about using this door at night. Anyone light you can shed on this would be very much appreciated.

Dear Rick,
These are European Hornets, an introduced species that might be negatively impacting native species by preying upon them and displacing them in the food chain.  They might have a nest in the attic.  We have read on BugGuide that they are attracted to lights, so your letter is evidence that is correct.

Dear Daniel,
Thanks for the quick reply.  You certainly nailed this one.  According to the literature you referenced, the nest will move on after the queen dies.  (I made a small donation to your site.)  Thanks again.

That was very kind of your Rick.  Thanks for the support.
