I don't understand what you mean? I was around plenty of clover as a child and never got stung once, neither did my siblings. It's not that hard to avoid bees/wasps/bumblebees. Besides, most times they are too busy buzzing around the clover flowers (when they are in bloom that is) to even be bothered that you're there to begin with. The bloom doesn't even last that long.

If you teach the kids to respect their environment and be cautious during blooming time, they are pretty good at avoiding getting stung/bit by the pollinators in general.
