Thanks Kate for the cautionary. The reactions that I have been experiencing of late are pretty rad swelling and almost instantaneous infection, and this last time a little dizziness included. Whether that qualifies as severe I'm not sure, but it is a step or two beyond when previously barely getting any reaction at all from stings. i really do fear the Giant wasp in particular, like the bad guy who rides into town and people stay in their houses and close their curtains as a result. One hostile encounter is definitely enough. I need to get an expert opinion on whether further consideration is required. Appreciate the heads up.
