HOW TO UNFRIEND ARMADILLOS
Posted on Jul 13, 2013

Try an ultrasonic pest deterrent device. A few different models promise to remove armadillos, skunks, and other visitors from your yard. A less expensive method (that won’t annoy your dog or cat by accident, as an ultrasonic device can do) is to simply make the areas they dig in smell bad to the armadillo.

Armadillos have sensitive noses. (The armadillo’s olfactory bulbs — the part of the brain that detects odor — is about 1/3rd the size of their cerebrum, the part of the brain used for thought, learning and memory.) Anything with a strong, noxious odor can help evict an armadillo from a den. Mothballs have been used successfully in the past. They also do not like the smell of pine mulch (they avoid foraging in areas with needles). Placing mothballs around the areas you most want to protect can keep pesky burrowers away. Peppering your whole lawn with them might be a bit drastic, but they might help you save your flower garden.
 
Removing an armadillo that lives in your yard
If you have an animal burrowed in your yard, you probably want it to leave. The simplest method of removal would be to try something with a strong odor to encourage it to move out. Dropping mothballs down the hole might help evict it. If that doesn’t work, you could always try a rag soaked in vinegar or ammonia (anything with a mild form of ammonia, like Windex, should be enough to do the trick — if it smells bad to you, it ought to smell absolutely awful to an armadillo).
 
Trapping an armadillo
If the armadillo that is causing you problems doesn’t live in your yard, or if you can’t find the burrow, you might consider trapping it. Armadillos are usually active early in the morning or late at night. You can either get up early or stay up late and attempt to net the critter if you see it, or you could get a normal amount of rest and let a live trap do the work for you. If you would like to try a live trap, first make sure it is big enough to hold an armadillo. They are around the size of a large cat when fully grown. Bait the trap with fresh fruit or earthworms. Worms probably will work the best; fruit might just attract a raccoon instead. If you use worms, put them in a nylon stocking. This will let the smell out without letting the worms escape.
