    • I got stung by 3 of them once and it hurt bad. I’d learned from my late mother to wash an insects bite/sting right away so it doesn’t swell(I think it relates to washing off whatever chemicals they release onto the skin when they sting you). So I immediately washed their stings and they didn’t swell. It was painful, though.
