[3] Both previously and in his current show, Bretherton is known for his unusual fashion style, consisting mostly of Goth-like black garments (many of them leather) with large silver jewelry and steel studs and spikes in various configurations.

He has stated on camera that the leather is tough enough to block most bites and stings, while the studs/spikes serve to intimidate animals and make them reluctant to attack him.

Many members of Bretherton's family, such as his parents, "Big" Bill and Donnie, and his brother, Ricky, as well as other employees, make frequent appearances.

[citation needed] Billy Bretherton entered the United States Air Force at age nineteen intent on a career in law enforcement.

His extermination career began in earnest while stationed at Nellis Air Force Base in North Las Vegas, Nevada.

"Back in 2004 Pilgrim Films contacted us and wanted to shoot a pilot for Discovery Channel (that was a) reality pest control show", said Bretherton.

In late 2012, Bretherton left Vexcon because of personal family issues and moved to Illinois; officially ending the show after six seasons.
