Armadillos dig their holes only to seek food. They feed on the little creatures like ants and grubs that reside under the surface.

In their food-seeking, Armadillos create larger-sized holes that can be up to 6 inches wide.

Earthworms act similarly to the Armadillos as they create holes along their food-seeking operations.

However, earthworms seek moisture/water, and they are more active during the spring and summer, that’s when you’ll most likely encounter the earthworm’s holes, which are smaller-sized compared to other holes.

Fix: You don’t need to kill earthworms which are beneficial for the soil, then you need to deprive them of moisture by keeping the area dry and watering wisely.
