Being a biker that used to attend a run & camp out every weekend I always carry Absorbine Jr. They make a convenient size small dab on bottle. My ex-got stung by a wood bee (nasty SOB's they are) dabbed on the A Jr. and in 20 minutes the welt was gone and he couldn't feel it at all.

I got stung at least 15 times by yellow jackets while mowing in the bushes one time and again in 20 minutes ........... no pain or welts at all. Same thing with a small scorpion.
