Sometimes wasps have other ideas about "treading on them" like "You are near and made a sudden move, you are threat". It gets worse when you are allergic to wasps. I've worked near a place where transport company cleaned their syrup and milk carrying trailers, so we sometimes had a lot of wasps and one of coworkers had to constantly have adrenaline with him. If he got stung and couldn't do it himself, we were trained on how to jab him and call ambulance.

FWIW, this bit is true of everyone I've known who was aware of an anaphylactic allergy, independent of their likelihood of exposure to the allergen. "Carry an EpiPen, know how to use it, make sure some of the people around you are aware of your allergy and know how to handle a reaction" is a very light-weight and reliable solution to "something relatively common could easily kill me".
