Kill ants and their nests in the home with Rentokil Ant Killer Gel. The bait station contains a specially formulated gel containing the active ingredient d-Phenothrin, which not only kills off the ant colony but also the queen in the nest, thereby halting reproduction. The worker ants are attracted to the gel and carry it as food back to the nest. Suitable for indoor use only. Prevent access to bait stations by children and/or pets.
