The first light of morning can reveal random pockmarks in what had been the perfect lawn the previous evening. The culprit is not likely the neighborhood teenager with a reputation for inappropriate practical jokes.
The offender usually is the nine-banded armadillo, sometimes referred to as a Florida-speed-bump or Possum-on-the-half-shell. In addition to manicured landscapes, they also encroach in natural areas and destroy sensitive habitats.
Armadillos eat adult insects and larvae, but also quail and turtle eggs. They incessantly dig holes in their search for food, many times uprooting plants in their food search. Their foraging holes are approximately one to three inches deep and three to five inches wide.
Using insecticides in landscapes to decrease the armadillo food supply is not guaranteed, but may help reduce the digging. In cases where there is a large, and always ravenous, armadillo population this reduction of food may increase digging activity as they search more diligently for a smaller food supply.
Another consideration is all chemical treatments have to be reapplied on a permanent basis for long term control. Always read and follow label instructions for safe use of insecticides.
Armadillos rest in a deep burrow during the day and are usually active after dark. Burrows openings are approximately seven to eight inches in diameter, about the size of a one-gallon plastic jug, and up to 15 feet in length.
This exotic invasive may burrow under driveways, foundations and patios potentially causing structural damage. Additionally, their burrows in pastures pose a potential leg-injury hazard to large wildlife and livestock.
Several live-trapping techniques can be used to capture armadillos as they exit of their burrows. Because armadillos are nocturnal, trapping techniques designed to capture them as they emerge from their burrows should be applied late in the afternoon and checked several hours after darkness.
Fencing is another option to discourage the presence of armadillos. Relocating captured animals is illegal and not recommended because it only transfers the problem elsewhere and can spread this problem species.
Fossil records indicate the armadillo’s ancestors were as large as modern-day rhinos. One can only imagine what front yards would look like if they still existed.
