Advion Ant Gel Bait by Syngenta is labeled to control 19 different key ant species. That is more ant species than any other gel bait currently on the market. The highly attractive and palatable formula delivers fast results and maintains its effectiveness over longer periods of time. The active ingredient Indoxacarb allows ants to consume the bait and return to the nest where they contaminate other ants, resulting in significant if not elimination of ant populations. This product is labeled for indoor use. Please see product label for all listed ant species.
