The Gel Bait is waterbased, and will dry up after a few days. The cockroaches will continue to eat it, however, applying fresh bait periodically is highly recommended. Just scrape up the old bait and toss it in the trash. A putty knife or spatula will work. If the roaches are dead and gone, then stop applying bait. Preventive baiting is not recommended, only to control existing infestations.
