It might be easier to breed or to hybridize a new species of large hornet or wasp, which are amenable to electronic control from a chip they are carrying - which implants into their own nervous system. Some of them are over 5 cm in length already. They are probably amenable to being steered by certain natural stimulate.
This kind of remote control is happening with mammals - why not insects? http://www.independent.co.uk/news/science/scientist-who-gave-rats-sixth-sens e-promises-bigger-revolutions-ahead-8498635.html It would probably be easy to change the venom that the hornets carry to some kind of nerve toxin. Yikes.

We are basically there now, assuming these things aren't too noisy. Eric
