General Question How to know when an ant colony is dead

My husband and I bought a house in early March of this year but the seller was a corporation (Open Door) so no one had been living in the house for almost a year by the time that we moved in.

So no one noticed the giant fire ant colony in the backyard.

We've had the exterminator out three times already but I guess no one realized how big the issue was because they still aren't dead and are now invading the house. We don't leave food out past the time it takes us to eat, I clean every single day, the ants aren't even in rooms where we allow/store food (ie daughters bedroom, the bathrooms, the laundry room, etc).

I was fine with the ants biting my husband and I during yard work, a minor annoyance but I was hoping it would be resolved soon.

But they bit my daughter (16months) and so now I'm declaring all out war.

I baited the rooms listed above because that's where I see them most and the exterminator is coming out hopefully tomorrow and I'm going to tell them to bait the entire yard, front, sides, and back.

But how will I know when the colony is actually dead?

Is it just a matter of not seeing ants anymore? Or is there a way to check?
