[starship troopers] why don't the arachnids launch a full scale attack on earth?

After behemacoytl consumes the Sky Marshal, he had ample time to send the information back to the other Queens to launch a full scale attack in earth, as they now knew about all of earth's military.

They can't. They didn't hit Buenos Aires with an asteroid either.  The government did to drum up support for the war while drawing attention away from domestic problems.  Unless you believe that the bugs threw a rock across the galaxy and the Federation somehow missed it?


Buenos Aires was an inside job.


There is no indication at all in the movie that the Bugs have FTL, they probably colonized other planets the slow way.
