Ellie, this may be a granny sucking eggs obvious thing to say, but .....
When are you getting stung?
Are you dressing for the worst but hoping for the best?
I wear a very thin fleece over my upper body while inspecting - gives more depth of clothing than warmth.
I also wear a baseball cap to keep the brim out of my eyes but protects contact part of head as well?
I also have a red badge on one of the pockets, this seems to draw their attention and it regularly gets stung -but its on a double layer pocket - so I dont.
Gloves, only wear something thin if you plan to handle/mark bees otherwise go for thickness. I have some good thick black nitrile gauntlets, still got more feel than leather but easier to keep clean, the girls can't even get a sting into them, let alone through.
There is nothing macho about getting stung 'because I don't need gloves' etc
Perhaps I am lucky? I know my suit gets stung with regularity, but I don't
Risk assessment: eliminate risk if you can, manage/mitigate if you can't.
I hope there is a way through this for you. R
PS ammonia applied immediately after a sting in theory helps because highly alkaline, also a scraping action to remove the sting - never squeeze the venom sack to remove!
