The US has far stronger rule of law than Mexico (one of the reasons so many Mexicans desire to come to the US), and I'm primarily talking about the difficulty of uprooting the narcos in Mexico.
That said, yes, I would expect to see a rise in cartel violence in the US at least out into the medium term. "Attack a farm" is a bit cinematic, but "threaten executive's children to extract kickbacks" is quite plausible in certain areas. Their area of influence now tracks traditional drug trafficking routes & illegal immigration routes, which covers a hell of a lot of the US. That doesn't mean they're necessarily dominant over that the same way they are in MX, but is something one should be aware of.
Their problem is that they will lose most of their income which will reduce their power. They may try some kidnappings, but then they also have to contend with the U.S. power plus the ability of the other side to buy protection.
