How long to wait to spray? Or should I do everything at same time?
You should use all of the products at the same time. Spray the Demon into cracks and crevices around door frames, window frames, baseboards and under appliances. Place the Advion Gel bait directly in cracks and crevices in cabinets, drawers and around counter tops (places where you wouldn't want to spray because you would contaminate food products or dishes). Place 1-2 Gentrol Point Source in each room where you have noticed roach activity. By using all of the products together you will get much better results in a shorter amount of time.
