Exterminator sprayed insecticide. Freaking out.

I just had my regular exterminator visit my house for a mouse issue indoors. It’s ongoing. I walked out the door and saw that he was spraying insecticide on my Joe pye weed and iron weed. I immediately told him to stop. He said he sprayed the length of the plants. He was very apologetic and I did explain native plants to him. I immediately rinsed off all of the plants for about five minutes with a strong spray from my hose and then rinsed off all the plants surrounding them with the same hose at a strong spray. I also tried to rinse as much of the soil as I could. are these plants/ the insects now visiting them now totally fucked? He said it was broad-spectrum. I’m so upset.
