The best advice I can give is to try to keep them out of buildings, structures, etc.
You can apply Termidor SC to the base of the buildings as a spray, and you can also do limited ground spraying (this use is restricted in many counties in Texas, read the supplemental label to see if you county is listed).
Termidor is not used indoors other than as a foam (Termidor Foam) inside walls, voids, etc.
For the open acreage areas, the only possible solution is the KM Ant Pro system. This system provides a feeding source for the ants that kills them. The cost of doing this over 19 acres would be fairly prohibitive, but again, that depends on how bad the ants are and how bad you want to get rid of them. You would need about 8 KM Ant Pro Dispensers per acre.
There are no easy cures, remedies for the Tawny or Crazy Rasberry Ant. There are also not very many options for control. Texas A&M is aggressively researching this ant, but so far, no easy controls have been found.
Its kind of like trying to change the weather. It's mother nature at work, and no way to stop it. Only do the best you can do to avoid it.
