I've never hired an exterminator, I have lived in TV for eight years and I grew up in Florida. Two products I use;
This bug spray is $4.44 at Lowes and they 68 in stock at the store on 466A. Spray it along the floor at all the entrances to your home. The sliding glass doors, the front door and the door from the garage.

This powder is $3.28 at Lowes and they have 16 in stock. Put this powder on the floor behind your refrigerator and stove and in the garage somewhere that animals cannot reach, we put it behind the washer and dryer. There is a similar product at Walmart called Roach Away, which is what I'm using, but they are identical.

The only time I might see an ant, is after a big rain storm and if so, usually in the bathroom. This product is available at Publix for $4., it's a small bottle, if you see ants put a small amount of this somewhere on the floor in a corner, you'll find dead ants within a couple of hours, they will come out and drink this stuff and die on the spot.
Your Welcome!
