Jim, what you have there are potato bugs, or "tater bugs" as the old timers would tell you. What you really need is some diazinon if you can find it. Don't worry about killing a few lady bugs, Clemson University released millions of them by helicopter into the local govt. forests for the fight against the pine beetle, so I've been told. Since that time, we have been infested with the critters. They get into houses, buildings, and I even had em in my new truck . How they got in I don't know but I don't think you will hurt the population of them with your seven dust. The potato bugs are really bad up here, they hit the potato vines, tomato, and a lot of other green leaf they will eat. "good luck"
