There must have been other Yeerk invasion spots

They didn't have mass-produced Kandronas until like the late #30s; they woula had to start with pools.
I think they definitely had pools in Cleveland and Columbus, Ohio.
They had to!

Well...we never saw them until the #30s, that doesn't mean they weren't there, theoretically x3

Not just the one in Northern CA where the Animorphs fought.

When the book series was released in 1996, there were 5 billion people plus and counting.

It would have taken years or even decades for yeerks to conquer the human race either completely or enough of a percentage of humans to take over the world with relative ease.

Why did Visser 3 choose that particular city for his main base?  Why didn't he move his main base when he ran into opposition from the Animorphs?

They already pretty much explained this in the books, that Edriss specifically chose the U.S. as a starting point as that's where the concentration of power was.  She chose L.A. as a starting point due to all being the major communications/broadcast hub and found a sort of more manageable satellite area around the general vicinity (I guess just any average mid-sized common California city/big town) to lay roots in.

So, there probably wasn't a situation of multiple little Yeerk operations nationwide, the plan seemed to be "slowly take the U.S., once that nation has a foot on its throat, expand forcefully".

But why didn't Visser 3 move his base when the Animorph attacks began?

I boggle at the fact that the Mighty Yeerk Empire couldn't arrange to smuggle a portable Kandrona generator to Tom when he had to leave town for 4 days to attend his grandfather's funeral!  (The Conspiracy, IIRC).

[Chad32]

Me too. Hell, they could have just followed him, and switched Yeerks one night if he couldn't get a PKM. his should not be such a crisis that plan B, after just begging to stay, is to do a drive-by shooting on Tom's dad.

Not to mention that, because of imcompetence on the enemy's fault, Jake blew the best opportunity to save Tom since book 1. Maybe not handing tom over on a silver platter, but still. It was an idiot plot, and probably my leats favorite book.

As stated in Visser, the Yeerks decided to start with America because it was seen as the most powerful Earth nation. They could have kept going in secret until all or most of the US were Controllers before declaring open war on the rest of the world. Doesn't sound so stupid to me.

It's possible that there were Yeerk forces in other countries, but think about the vast amount of time and resources it would have taken to build an underground Yeerk Pool and an Earth-based Kandrona generator in secret. To do that in multiple in countries would take a long time and be mostly unnecessary since they had access to Kandrona rays on the Pool Ship. And if we assume that the only Earth based Pool was in California, then it wouldn't make sense to start infesting humans in other countries if they had no easy access to Kandrona rays.

I would build lots of mini-Pools for the Yeerk agents in other countries.

I would seek to infest the United Nations.  The infested UN ambassadors would then infest all the national leaders!
