Flea Beetle – Control
Q: What could cause all these holes in my eggplant leaves?
A: It’s flea beetle damage. They attack radish and mustard leaves too, but eggplant seems to be their favorite food in my garden.
You can use organic controls like diatomaceous earth (click for sources) or Pyola (a pyrethrin/canola oil combination) or a synthetic insecticide like carbaryl (click for sources) or Bayer Systemic Vegetable Insecticide (click for sources).
