could you shut up the hive and move it a few feet for a few days, place a new hive on the old spot with some jam inside it and place a false floor in it covered in sticky rat and mouse glue...
all the wasps that know about it bound to get caught in it after a day you'd think.

Possibly. It could achieve the same result. I guess the only way to find out would be to try. You'd need to be sure that no bees went in and there's potentially the problem of dealing with the glue afterwards?
