The solution to hitting yourself in the knackers with a hammer is not
to look away and hope it stops, the solution is to put the hammer down
and move away to a safe distance.  Fix the /problem/. (Yes, I know
this was a reply to a direct question, but sometimes the question is
so wrong it can't be answered in the form it's asked :-))

Either store a definitive list of host keys and construct your
known_hosts file pragmatically, or devise a way to remove entries when
instances are terminated. Don't simply eschew an important part of the
layered security that using ssh gives you. It's not just about
encryption.
