One of the stars of "Billy the Exterminator" was the one buggin' out this weekend -- when cops in Louisiana busted the guy for felony marijuana possession.
TMZ has learned Ricky Lee Bretherton -- one of the bug fighters on the A&E reality show -- was arrested on April 10 when a routine traffic stop turned into a big, green drug bust.
According to Leesville PD, officers approached Bretherton's car and located a "quantity of suspected marijuana as well as a container that had more suspected marijuana as well as drug paraphernalia."
Bretherton and a female passenger were each arrested. Bretherton was charged with felony weed possession, felony drug paraphernalia possession and a traffic charge.
Bretherton's bond was set at $4198 -- he was released on his own recognizance.
