A sports stadium with a bat problem is tackled. Also: a vacant house filled with mice and an enormous snake.

Billy tries to catch a bothersome beaver, but discovers some poisonous water moccasins blocking the way. And when a dentist's office is filled with a mysterious stench, Billy sniffs out the cause--it's a dead cat under the building.

Billy meets the two houses from hell. In the first, he races to get rid of destructive termites so the client and his family can sell their house and get out, but everything that can go wrong does go wrong. And at the other house, Billy has to chase a family of possums that has moved into the walls.

Billy deals with a case of reptile dysfunction when he's called to a ranch to handle an alligator that's threatening some pet llamas. Plus, there's more dysfunction back at the office when Ricky breaks up with ex-wife Pam--again.

It's time for a creature feature. There's a mystery creature living inside the walls of a fancy home, but when Billy investigates, a violent animal attacks. And later, Billy must deal with a major black widow infestation at a home where three small children live and play.

Even Steve Irwin, the famed "crocodile hunter," probably never faced a hair-raising situation like this. Billy must brave a dozen alligators to get rid of a dangerous fire ant infestation at a gator park. Later, he must squish out one of the worst swarms of roaches he's seen in 20 years.

This episode is definitely not for the faint of heart. When Billy and Ricky are called to an old haunted plantation plagued by raccoons, they find the biggest mound of raccoon excrement they've ever seen inside the attic. (Hey, it's a dirty job, but someone's got to do it!) And things get even worse when Billy goes to the home of a deaf couple inundated with hundreds of wasps!

A big gator has been threatening the dogs at a family farm, and Billy is called in to save the day. But when he catches the beast, the gator attacks and takes a bite out of Billy.

Lots of people get snake tattoos, but a real-live snake has invaded a tattoo studio. And it's the most venomous snake Billy has seen in 20 years. Later, Billy gets one of the strangest calls of his career --six wild turkeys are running amok at a club! And Donnie and Bill Sr. secretly take out a personal ad for Ricky and then set him up on a blind date.

Billy must face down a wild bobcat that has killed a family pet, but the elusive cat isn't easy to catch--and there's a surprise in store that Billy doesn't see coming. Later, Billy battles to get rid of a wasp infestation that has forced his client right out of her home.

Dam it all! When Billy fights to trap a beaver that has been eating through the trees on his client's property, he discovers there are more than just beavers lurking in the wilderness. Later, Billy takes on an extreme roach infestation that has forced his client out of house and home. And things get pretty rough back at Billy's home, too, when tensions between him and Mary begin to escalate.

Skunk alert! Billy goes to a horse farm where a potentially rabid skunk has been on the prowl, but when he catches it, he gets more than he bargained for. Later, Billy takes on what he thinks is a simple mice job--and winds up getting bitten by a snake!

Billy faces an angry mother raccoon trying to protect her young from his snare, and then goes on a mission to exterminate a seven-foot-long beehive. But bees aren't the only thing that are causing a buzz in the Bretherton family. Ricky's ex-wife, Pam, has returned to work at Vexcon, and that's rubbing some of the Brethertons the wrong way.
