You basically have to take the rock and bore the little buggers out. I spent a couple of hours digging those suckers out 3-4 pcs of rock. They will spread if you don't remove them.

So boiling isn't an option? The rocks aren't that big and manual removal would leave me with pretty much nothing but small rubble. I don't really feel like going out and buying more rock that might have the little buggers on them.
