Clean up the yard. Keep it mowed. Trim off low limbs that offer shade and shelter, thin bushes, that will make it less attractive to critters. They dig dens in sheltered locations so open everything up to eliminate hiding places. Don’t plant vegetation up against buildings. Close off any porches or decks or crawlspace under buildings and sheds.
Make sure there are no open trash cans and that all kidded cans have bungee cords or other fasteners to insure animals cannot lift the lids.
Animals are attracted to junk laying around, brush piles, water, and of course, a food source.
Don’t put out birdfeeders if you don’t also enjoy the other varmints that are attracted to the grain. Raccoons especially will congregate where there are birdfeeders, or cat ladies who leave food outside for stray animals and pets.
Most animals aren’t a big bother, and can actually be enjoyable, if you just have a tidy yard and don’t leave any kind of pet food or birdseed out overnight. I have bobcat, coyote, fox, raccoon, otter, opossum, woodpeckers, hawks, owls, eastern diamondbacks and water moccasins plus all the harmless snakes and turtles, ducks and wading birds here. The only species that is extremely bothersome are the raccoons and peiple’s wandering dogs, and coyote. But I had very little trouble with raccoons when I had a dog, even though they were very attracted to my poultry.
Armadillos are just looking for grubs, which is beneficial. If you don’t want armadillos, treat your grass for insects regularly to insure that there are no grubs. They will dig in any mulch laid down because mulch attracts insects they like to eat.
Some very sound advice. Thank you.
