Ortho 0275510 refers to a legacy fire-ant product listing. The useful distinction is its dry mound-treatment format: it should not be confused with an indoor ant bait, a general-purpose household dust or a different Ortho lawn granule product.
Check the actual container
Older Orthene Fire Ant Killer labeling identifies an acephate powder for outdoor mound treatment. The EPA’s historical label record is useful for understanding that product, but a 2007 record does not establish the instructions or availability of every package sold today. Match the product name and registration number and use the labeling supplied with your container.
Do not buy old stock with a missing or unreadable label. A seller’s model number, photograph or claim about how many mounds a bottle treats cannot replace the application and precaution panels.
A mound treatment has a specific job
This format is intended for treating visible mounds in labeled outdoor locations. It does not provide evidence that unseen nests across an entire property have been controlled. After treatment, evaluate activity according to the product directions rather than assuming the first dead workers mean the colony is gone.
The historical dry-powder directions explicitly say not to water it in. Do not borrow watering instructions from another fire-ant product. Similarly, do not turn the powder into a homemade spray or apply it inside a house because it kills insects outdoors.
Handling and practical limitations
Use the factory opening and dispensing directions without modifying the cap or seal. Keep powder off people and pets, avoid dust exposure, and follow the container’s protective-clothing and reentry instructions. Keep the original labeled container securely stored.
For a small number of accessible mounds, targeted treatment may be easier to manage than a whole-lawn application. For numerous mounds, uncertain identification or an area where people and animals cannot be excluded, seek advice on an appropriate overall control plan before purchasing more powder.
What this review can establish
We have not verified a universal three-year shelf life, a current price advantage or a guaranteed kill time for model 0275510. Those should not determine a purchase. The defensible assessment is narrower: a correctly identified, properly labeled mound product may fit that task, while an unidentified old bottle does not.
Our ant-control guide compares treatment categories. Choose by the ant problem and permitted site, and obtain current product information from the manufacturer when the legacy listing and the bottle disagree.
