Do moth balls keep armadillos away?

While mothballs are useful for keeping away unicorns, gryphons, griffins, manticores and moths. They do not seem to work on armadillos. The only way I have found to keep the house from being over-run by armadillos is to invest in croquet mallets and hoops.
You use the croquet mallets and hoops for a game of croquet with the rolled up armadillos, this upsets the armadillos, and they soon stomp off, muttering to themselves, never to return.
