In south Texas, residential communities are often built on top of bayous, marshes and swamps, allowing alligators to live dangerously close to small children and pets. It's common to see alligators in backyards, under cars, on golf courses and in shopping center parking lots.

When that happens, residents of Houston turn to Christy Kroboth, also known as "Gator Girl." Kroboth is a former dental hygienist who now makes her living wrangling reptiles. She and her business partner, Chris Stephens, trap nuisance alligators and relocate them to areas where they'll pose less risk to the community.

CNBC caught up with Kroboth and her business partner, Chris Stephens, outside of the Bayou City sneaking up on a gator – with a fishing rod.

When a 900-pound alligator that Kroboth dubbed "Godzilla" showed up in the local Home Depot parking lot, 100-pound Kroboth did not hesitate to jump on his back and tie him up.

"It takes a lot of courage," Kroboth tells CNBC. "My mind tells me, 'Stop, get back! It's dangerous!' but the other part tells me, 'That's your job, you gotta get these gators!'"

After the gator takes the bait, Stephens reels it in close to the surface, as Kroboth wrangles it with a lasso before wrapping its jaws shut with her signature pink tape.

"I got into the nuisance alligator program because most of the [other] guys… kill the alligators," says Kroboth. "I got into it to beat the guys out there — and take the animal alive." And Kroboth makes a decent chunk of change doing it.
