The Golden Skull Alliance struggled to secure their spoils. Even after they had taken control over all of the important systems of the captured pakklaton ships, the vessels continued to deteriorate as the voribugs kept gnawing on everything.
The soldiers tried their best to detect and exterminate any concentration of voribugs, but there were way too many juvenile bugs that slipped away.
There were also cases where one or two voribugs remained undetected because they lingered around ship components that produced a lot of activity. The relatively weak lifesigns of an immature voribug would get drowned out by more powerful energy emissions of important systems.
Even if the Larkinsons shut down all of the systems, all of the residual heat and energy inside the alien vessels wouldn't dissipate immediately. The damn voribugs seemed to possess a vague instinct that encountered them to find the most annoying hiding spots on a starship.
