Solenopsis invicta are a lot more aggressive too. The good news is that you will not be finding them everywhere. Orange County is probably getting it the worst, but it is both too dry, and too cold sometimes up here around Ventura County for them. Also I doubt you will be finding them in the desert.

Both Linepithema humile and Solenopsis invicta originate from the same place. Also, here in Simi Valley at least, I have never seen a single worker of Linepithema humile. I have a feeling that Nylanderia vividula are aggressive towards them and since they have a very strong foothold in Simi Valley, they can keep them out.

I only see S. invicta in North County. Anaheim for sure.

Up in LA I saw my first solenopsis colony at my house earlier this year.

I haven't ran into a single Solenopsis invicta colony here yet. I haven't really been looking but I'm sure I would have noticed them if they were here. I want to try and catch a queen these upcoming seasons. 

 

Edit: Never mind. It seems they haven't established here yet. Which is weird because they are in California and New Mexico.

Solenopsis invicta killed somebody in arizona, and it was a huge thing. BTW I've never found an actual colony, i just see the queens in my pool. 

[kellakk]

Yeah, I can confirm that they're pretty much everywhere from Orange County to San Bernardino County too now.

[Thomas_Nguyen2456]

I don't see anything in North Hills.

I kind of want some.

Texas has tons of them...

This species reproduces like crazy. I see alates most days in the summer, and sporadically throughout the entire year.
At least they've kept argentine ants in check here in Austin (we've got both). It seems like the RIFA take over areas most effectively after a large disturbance that kills off lots of native ants, like a pesticide spray or construction. I've seen quite a few places where people applied lots of pesticide over everything thinking try had fire ants (when they really only had a few colonies), then try had hundreds of RIFA mounds 6 months later.
The only species that survive in these areas aside from S. invicta seem to be Crematogaster and Dorymyrmex.
It seems like in areas that have a good diversity of ants (like my house), S. invicta don't take over everything.

I'm from where S.Invicta was introduced. And they've spread from here. Running a muck on crops. I do see them living with and around Argentine ants and others. After getting into anting I noticed tons of them. I caught 11 of them last week. In about 70 years they spread from coast to coast.
