FORT WORTH, Texas -- Husband and wife Mario and Brandi Nickerson are handling precious cargo inside a red bucket labeled "venomous snake."

"The things that everyone else doesn't like we take them in, and we take care of them -- that's just what we do -- that's what we love to do," said Brandi Nickerson, a co-founder of Nature's Edge Wildlife and Rescue a nonprofit she started with her husband since 2012.

Since then, about half the animals they handle are snakes, especially this time of year. "A lot of people think snakes are aggressive or can be aggressive, but they're not aggressive, they're defensive," said Mario Nickerson.

That can mean that perfectly harmless snakes are killed by homeowners that just don't know any better. This Facebook page they manage is playing a role in stopping that.

"It was started with the mission of just trying to identify snakes and hopefully curb people from killing them and to be honest, it's done that," Mario said.

About 67,000 members are part of the page, "What kind of snake is this? North Texas."

"Take a picture, post it and we can usually get an ID within five minutes if not a lot sooner, and tell you if that snake is venomous or not and go a lot further, and tell you the roll that plays in the ecosystem," Mario said.

The big take away? Snakes will leave you alone if you don't bother them. In other words, take your picture from a distance.

Their advice -- keep your lawns mowed, bushes trims and if you do come across an unwelcome guest, chances are they'll slither away before you have a chance to post the picture.
