Large wasps coming into house at night, attracted to light. Never saw so large of a wasp or bee.
Hi, I do not know where these large wasps or bees are coming from. The do not seem aggressive. Over the past 3 nights I have needed to kill at least 5 to 7 a night. The light attracts them in the kitchen. So they hang by the door and fly in when they can. Thanks.
Those are European hornets. As you've noted, they fly and are attracted to lights at night.
Their nests aren't easy to locate. We suggest turning off outside lights and drawing shades if you can. They won't be around much longer.
Here is our page on them: http://extension.umd.edu/hgic/european-hornets
