The Advion Cockroach gel bait and Advion Cockroach bait arena formulations contain different sources of sugars and proteins, which attracts cockroaches differently. "The Big 8" allergens are not present in the Adion Cockroach gel bait. Advion Cockroach bait arena consists of a solid paste that is housed in a plastic container, providing protection against contaminants, children, and pets. Further, the Advion Cockroach bait arena is useful in areas where harsh conditions may compromise gel baits, such as high moisture or humidity, extreme temperatures, or dust. In addition, it can be used in sites that are difficult to service regularly.
