Dry open grassy areas or open forest adjacent to grassy areas. They can also be found in urban, suburban and agricultural areas, and on barrier islands.
How to Find
Walk along field-forest edges, particularly in Spring and Summer. These are the fastest snakes we have (thus the “racer”) and can flee readily, but will also stand their ground and strike repeatedly. Bite and release musk when handled, squirming to get away. Non-venomous, but the bite can be painful.
