I know to spray around the the plumbing, looking for long term protection.
Our most popular product is Dominon 2L for termite treatments. You should treat the entire area before they pour the slab. This is called a pre-treat. You should apply the product at a rate of 1 gallon per 10 square feet. Some of our customers also use a 5 gallon bucket and pour the 5 gallons over 50 square foot sections which will be much faster than using a hand pump sprayer which comes out slowly. It is very important to apply more around the perimeter edges of the slab, around plumbing pipes that will come through the slab, and along expansion joints if you know where they will be. Since these are the more likely entry points of termites you want to make sure you treat more heavily around these areas. You should take general precautions when applying any product which would be to wear gloves, protect your eyes if it is windy, and treat only in the designated area where your slab will be poured. This treatment will protect your home for 7 years, after which you would want to re-apply a termiticide around the perimeter of the house as outlined in our How To Do A Termite Treatment article.
