i have literally dozens of bees/wasps flying around my plants at any given time, yellow jackets, honey bees, shiny black wasps, and typical black/yellow striped wasps. they love the nectar! i have never been stung, and have been doing this for years. i take that back - i was painting our house last summer and found out the hard way i was standing on the yellow jacket's nest entrance. anyway, i've never been stung when i'm by the Sarracenia. i think they are too preoccupied with the nectar to care about someone watering or cutting off dead leaves or whatever. if you don't bother them, they won't bother you.
there's always a few that are going to get caught, but it seems, especially with the wasps, they'll chew a hole and escape that way.
