If you really think they are Giant Asian Hornets, you should report to the authorities, probably the state Department of Agriculture. As stated above, I don't think they have been found in the U.S. except a few in Washington. But if they are there, the authorities will want to find any other nests that may be in the area and destroy them. Those hornets will devour a honey bee colony in a couple of hours and are extremely dangerous. I believe I have read that their sting can cause kidney damage or death for some individuals.
