I've never heard of fig wasps before, and I don't really care if we have them here or not. I love fresh figs, and fig jam (which I make a very delicious version of I have to say) and if they've got grubs in them, well, it's just extra protein anyway. Same with guava's. It's pretty hard to get a tree ripened one of those without grubs in it.
We're pretty rustic over here.
