Glenn,
Didn't see any answers to your questions so here it is from the desert southwest
where the ants will eat anything. Yes you can bury a shell here and the ants will
clean it out. Actually, I have only tried it once away from the beach and
something (probably a coyote dug up my shell and carted it off). But I have heard
others tell of using ants here. I prefere bleach but the ants will probably
oblige. As for the Tibia, last one I saw listed was by Guido Poppe, I think.
Finally, welcome to Conch-L. Hopefully your next question will get a bit more of
a response. I think everyone is a bit worn down by some heavy conversations on
ethics and the environment.
Have a great superbowl Sunday,
