[Jurassic World] How did they clean up Isla Nublar in order to build the new park?

The T-Rex i can understand was hunted down and put to sleep. 

But what about the velociraptors? They are too fast and sneaky. How many men did they lose before declaring the island safe again?

Is it even safe?  Or are there huge red zones that still need cleaning?

There were only 3 Velociraptors. 

2 got killed fighting the T-rex, the other one was probably still stuck in that freezer. 

The only other carnivore on the island is that spitting dinosaur, so that was probably the most difficult to deal with. 

They probably lured them into traps considering that they're generally curious at first before attacking (based on their behavior with Nedry).
