Fratricide is a Gas
Our guy Dilke is the first to be miniaturized to help earth solve over crowding problems. Essentially, everyone needs to get small so there is more room. Dilke is a “microagent” and is looking for the source of some poison gas. I guess since he is miniturized, now your every day bugs are giant killer monsters. Sounds scary to me. All I can think of is a roach motel as a hiding place, but I bet that wouldn’t be good for miniature humans either.
