With my tongue firmly implanted in my cheek...
Books, I "...double dog dare ya.." to climb up a tree and get a wasp nest and then make wads, shoot them at an official NCOWS event and then report back on how well they worked. The nest must be kept in your home for one full year as the test will otherwise be moot.
Please include pictures from the emergency room of your nurses applying specific ointments, bandages, slings, etc., as that will be the definitive answer to this question.
Best regards and don't shake the nest before stripping off the outer layers!
