Live-trapping these animals is an ideal way to control them, however, most folks that try this technique have poor results. The reason for this most do not know how to go about it. They buy a live trap, set it up and bait it with a variety of baits including bananas, rotten vegetables, fresh fruit name it. If you find an armadillo in a baited trop, more than likely it accidentally walked into the trap.
Some suggestions about humane placement and release would be helpful.
