How do you keep armadillos out of your garden?

I have put a fence up every year and not buried it and they haven't bothered the garden. Obviously being such good diggers I suppose they could get under it if they really wanted to but I think it wasn't worth it for them to mess with when they can dig up other places instead? I don't use any pesticides or chemicals as they kill the pollinators, which is, of course, counter productive. Hope that helps.

Since this reply, I have found a way to deal with these critters. A friend brought over a trap, made to catch these guys. He placed it in an area that was in a path the armadillo took. Important - don’t put any food in it. It was left there for a month before catching him. Then he took him to a wooded area and released him. It works!

"People often use mothballs in inappropriate sites and against incorrect pests," Stock said. "The only recommendation that counts is the product label, which is a legal document whose instructions must be followed – particularly on where mothballs may be used and which pests they will control."

Mothballs should not be used inside attics, crawl spaces, gardens, trash cans or vehicles. "Often, mothballs are used in these locations to control pests other than clothes moths," Stone said.

They include squirrels, skunks, deer, mice, rats, dogs, cats, raccoons, moles, snakes, pigeons and a variety of other animals. Any such use is illegal.
