please read PH's post again.I find if I ask on here, I get extra info, like on your post about them being a statement of intent...a book wouldn't explain that as well as you did, as you added that even if it has larva in, you can ignore it.
too right about that last bit!!! that was how I ended up in a queenless mess!!Yes, it is an egg in a play cup that you can safely ignore. Once there is jelly in there, you have a grub, if you can see it or not and the clock has started ticking.
That slight misunderstanding could be a costly error to make.
