Detailed Review
Ortho Orthene Fire Ant Killer1 is a targeted granular treatment designed to eradicate fire ant colonies in outdoor spaces. Supplied in a two-pack of 12-ounce bottles (680g total), it gives homeowners a direct way to treat active mounds on lawns and around garden beds without needing complex equipment.
The formula works quickly, starting to kill fire ants in just 60 minutes. It targets the entire colony, including the queen, to prevent the mound from recovering. Application is straightforward: simply sprinkle the specified amount of dry granules over the mound according to the label. Because the product requires no watering-in, treating problem spots takes very little time and effort.
Coverage is extensive, as a single 12-ounce bottle can treat up to 162 mounds across your yard. You can use it around various ornamental plantings, including trees, shrubs, and flowers, as well as throughout open turf areas.
While this product excels at direct mound treatments, Ortho notes that using their Fire Ant Killer Broadcast Granules (sold separately) provides the best overall results as part of a 2-step system. In addition, this treatment is strictly intended for outdoor use.
Verdict: Ortho Orthene Fire Ant Killer1 is an effective, fast-acting solution for property owners dealing with aggressive outdoor fire ant mounds. With its simple dry application and high mound capacity, this two-pack is well suited for anyone needing quick colony elimination across their lawn and garden.
