You might enjoy the superhero web-serial Worm. Then again, you might not- I had some issues with the story myself, and I don't know your tastes well enough to guess. But it certainly fits the criteria of being aware of just how much destructive (and occasionally constructive!) potential is available to someone with the ability to control all the insects (and, in the case of Worm, arachnids and other invertebrates) in the area.
