I haven't dealt with armadillos personally, but I've heard live traps baited with fruit or worms work well. Place them along their paths near the damage. You might also try calling a wildlife removal service if trapping doesn't work
Thank you for the reply. I tried worms to no avail - he's a tricky SOB! I might set up a game camera to see what hours at night it's most active. We have been dry in Blanco county and every spot I try to water it attacks- likes the soft dirt to dig for grubs,etc.
