How long will it go after applying Advion gel that you will find dead roaches
You will not always see dead roaches after using Advion Cockroach Gel Bait. This is because roaches are going to die where ever they die and this could be behind cabinets, in wall voids, or other areas inaccessible to you. You want to continue to bait as long as you see activity. With a heavy infestation, you can expect several weeks before you see full results. Please take a few moments to read our roach control article for more information on a complete roach treatment.
