About Orthene
A fire ant mound can hold thousands of workers and a queen that keeps the whole operation running. Step on the wrong patch of lawn barefoot and you'll understand why homeowners get serious about killing the colony, not just the ants you can see. That's the problem Orthene products are built around. This site breaks down the lineup — indoor ant bait, outdoor mound treatments, granules — so you know which one actually matches the ant problem sitting in your kitchen or your backyard.
The Products
Orthene splits its lineup by where the ants are. Indoors, the Ant Killer Ant Bait comes as 12 small stations you break apart and set along baseboards, under sinks, near pantry shelves, wherever foraging ants have been spotted. Worker ants feed within about 30 minutes and carry the bait back to the colony, so the visible ant trail thins out over the following days rather than disappearing overnight. It's labeled for common household species like pavement ants, odorous house ants, and Argentine ants — not fire, carpenter, or harvester ants, which need a different approach.
That different approach is the Fire Ant Killer line, sold in 12 oz and 14 oz bottles. It's a dry granule you sprinkle directly on the mound — no mixing, no watering in. One 14 oz bottle covers up to 189 mounds, which matters if you're dealing with a yard that has more than one problem spot. Ortho pairs this with a broadcast granule step for longer-term prevention, treating everything from lawns and turf to ornamental shrubs and flower beds.
Our Approach
We don't test every pest product on the market and we're not chemists. What we do is read labels closely — active ingredients, application instructions, what a product is and isn't rated to kill — and compare that against what homeowners actually report after using it indoors, outdoors, around vegetable gardens, or near animal quarters. Acephate shows up as the active ingredient across the Orthene fire ant treatments, and we think that's worth stating plainly rather than burying it in fine print. If a product only works on certain ant species, we say so. If setup takes five minutes or fifty, we say that too.
Why We Recommend Orthene
Ant problems rarely fix themselves, and guesswork wastes a weekend. Orthene's split between indoor bait stations and outdoor mound granules covers the two situations most households actually face. We put together the guides on this site so you can pick the right one the first time, skip the wrong aisle at the store, and get back to a yard you can walk across without watching your feet.
