You would actually need both products. Transport and Gentrol are two very different concentrates in how they work. Transport Mikron is a liquid insecticide that you would dilute with water and spray for residual control over the roaches and other insects. The Gentrol IGR has no killing properties in its ingredients as it is purely a birth control for the insects. Using an IGR like Gentrol is pertinent in making sure you halt the infestation. You can mix the Gentrol and Transport together in the same gallon of water and spray them at the same time.
