Battling Leaf Miners in My Dahlia Garden

I'm growing dahlias for the first time in years, trying them in grow bags this season, and they seem to be doing well. But they're under attack by leaf miners. Any suggestions on how to deal with them? I've got an organic pest spray with Spinosad on its way, but someone suggested I might need to deal with them systemically. If this is true, any suggestions on what to use? I also saw a YouTube video where the guy made a concoction of 500ml of water, 2 teaspoons of vegetable oil, and 1 teaspoon of dishwashing soap and sprayed the leaves thoroughly. Think that would do the trick?
