As a Floridian, I can tell you that ants are a year round problem here, UGH! Terro is the only thing that's worked for us. Just make sure your pets cannot get to it, as it'll make them really sick!
I am not sure it'll work on Carpenter ants. Those suck because they eat your house
You might have to resort to a pesticide spray
Good luck with this, I know it's frustrating!
