I am very allergic to these wasps. Some people think they are bees because they are so small. I carry a needle kit in case I am stung. I was told by an ER doc that I am between a person who swells excessively and/or dies. I am not sure about dying from them as I'll probably hyperventilate and die first.

Thanks Doc! They scare the #@!# out of me.
My grandma would say soaking down some tobacco with saliva and applying to the sting is the best.
