We'll, I've been a damn yankee for over 24 years now.
Skunks and ground hogs along have been on the east coast (and native to NC) since boats came to the eastern shores in the 1600's and they didn't migrate here recently to NC
Never saw an Armadillo in NC to be honest, but did see a alligator on the eastern side of the state. Wouldn't know what a fire ant looks like.
Coyotes came in about 40 years ago from Tenn.
From what I remember Dakota white tail are generally a larger breed of deer. Generally, NC is over populated with white tail and they are a lot smaller than most deer you'll find up north. Honestly, guys hunting deer in NC will shoot anything on 4 legs for the most part from my experience.
I'm guessing your on the east side of NC?
