About this product

Ortho Orthene Fire Ant Killer is meant for the mounds popping up in your lawn or flower beds, working directly on the colony rather than just the ants wandering across the grass. It's a dry powder, so there's no mixing or watering in; you sprinkle it over the mound and let it work. One 14 oz. bottle is labeled to treat up to 189 mounds, and it pairs with Ortho's granule treatment as a second step for longer-term prevention.
