I have noticed several people talking about RIFA (Red Imported Fire Ants, Solenopsis invicta) and wanted to throw some links out I have used to clean up issues with invasive species.
Here in California, you can call:
Free removal if you live in Orange County:

CDFA fire ant hotline: 1-888-4FIREANT or 1-888-434-7326
Or for pests in general call Pest Hotline: 1-800-491-1899

Since I don't live in other states, not sure what they offer or if their services are free.
However, here is a ton of links for states for you to see if it's offered:
