I'm an ant fan. Simply find a decent sized hill, wrap the antlers in tin foil (or anything to keep the sun off) and tie it down. I usually like to remove a couple of shovels full of ants and hill, put in the skull, and put the ants back on. Do this at the start of summer (say in June) and by August you will have everything gone. It may be hard to find, since the ants will have repaired and rebuilt the nest around it, but, dig it out and you will be amazed!
