In Breaking Bad in an episode called Hazard Pay, after Walter has killed meth boss Gus Fring, Walter, Jesse and Mike buy a fumigation company called Vamonos Pest. It is used as a front for their continuing criminal enterprise, but they also use some of the homes they fumigate to cook the meth so they will remain undetected.
Once a week, Walt and Jesse pick a house for a temporary cook location. Badger and Skinny Pete bring in all the lab equipment which is stored in roadie cases for Vamonos Pest. The Vamonos crew tents the house as usual and does the bug bombing after Walt and Jesse cook the meth. The crew also has to be sure not to burglarize the house they cook the meth at, so the homeowners don’t get suspicious. Before they bought the business, the Vamonos crew had their own racket they were running. They would supplement their income by burglarizing the houses they fumigate or selling duplicate house keys or alarm codes to other criminals. So obviously, many people are in on this. And they all need to be on Walter’s payroll, so they keep quiet.
One day, as Mike is divvying up money made after a batch of meth was sold, Walter makes the comment that now he’s making less money than he did with Fring. He’s a bit indignant and Mike calmly says, “Listen, Walter. Just because you shot Jesse James don’t make you Jesse James.”
Just because Walter killed Gus, it doesn’t make him better or even as good of a businessman as Gus was. Gus had been in the meth business for years and had gained experience through the years. Walter, on the other hand, didn’t consider all the people he would have to pay off and how to scale the business to make the most profit.
