Living in Canada, we don't have Armadillo's here, Not really familiar with them but I do think they are kind of neat, didn't realize they did much damage,, Of all the pictures I've seen of them I'm thinking beer is the best resource for them, as most of the pics I've seen are of an armadillo laying on it's back with a bottle of beer in it's mouth.. So wouldn't that work? Leave out some good beers, and let them drink until they pass out then just collect them up, and of course put them into a 12 step program...........
Cheers
