Eastern Moles live beneath Maryland lawns, meadows, fields, and open woodland in moist, workable soil. Raised surface ridges and fresh soil mounds are the usual evidence; seeing the animal itself is uncommon and generally follows flooding, excavation, or accidental exposure.

Records occur year-round and peak in May, June, and October. Because observations depend heavily on people noticing soil signs or exposed animals, the calendar is a record of detectability rather than underground activity alone.
