Any forested habitat with soil loose enough for burrowing. Also found in open fields and lawns.

How to Find

Look under coarse woody debris and within rotting logs, particularly in areas with moist, not wet, soil. Non-venomous. When handled they attempt to push their way between the fingers with their head or tail spine, but they do not bite.
