Surviving a Murder Hornet attack!
Surviving a murder hornet attack really depends on how fast you can run. That should always be your first line of defense, run like hell!. If you do happen to get stung, I really suggest that you don't panic and seek proper medical care, and not listen to some fictional characters that have not read one medical journal in their life. However I have read that its like getting poked with a red hot poker and the swelling will go down in 24-48 hours. Again seek proper advice. So in closing.
2. Don't panic.
3. Seek professional helps.
Hope this helps. This article and accompanying comments do not reflect any ideas or thoughts our fictional characters may have on the subject.
