I just spray three days ago, not seeing many big ones seeing most medium size ones, not seeing small ones either, just wondering how long should I wait to spray again.
Demon WP and Gentrol should be applied once every 90 days to indoor cracks and crevices and outside crevices on the exterior of the structure. We highly recommend applying a professional roach bait gel to the cracks and crevices that you have not sprayed with the insecticide/IGR mixture. The bait should be applied once every two weeks (make sure to clean up old bait).
