Sowbugs

Sow bugs, also known as woodlice, are very similar to pill bugs in habits, size (approximately 1/2-inch long), and color (slate gray with an armored plate look), except they have a small tail that makes rolling into a ball impossible. Sow bugs are most active at night, as they are nocturnal.

Sow bugs are drawn to their main food source: decaying organic matter. Much like pill bugs, sow bugs tend to remain outdoors. During the day, they can be found resting in dark places: under rocks, trash, vegetation, and boards or just below the surface of the soil. If they do come inside, they are most often found in dark and damp areas like basements.

Sow bugs can sometimes damage the roots of plants when they feed. However, when they do wander indoors, they don’t inflict any damage.
