      Great question! Ortho Fire Ant Killer Mound Treatment affects the nervous system causing paralysis, and the insect must come into contact with the product. It will kill the mound and the queen, as well as keep new mounds from forming.

          Hi Patricia! Thanks for your question. After applying Ortho Fire Ant Killer Mound Treatment, drench the mounds with 2 gallons of water. When watering, do so gradually so water soaks into soil and does not run off. Do not make applications in the rain.

              Answer This Question

              Thanks for reaching out! I understand you're looking for some guidance on how to best use our product. To get the best results, here's what you should keep in mind: Keep the area clear: Avoid disturbing the treated area by keeping people and pets off of it until the product has been watered in and the soil is dry. Wait for it to dry: Make sure to stay out of the treated area until it's completely dry. Once dry, it's set: Once the product is dry, it's very difficult to dislodge the residue, so any exposure would be minimal. No reactivation: If the area gets wet again (from rain, dew, or watering) after it has initially dried, the product won't reactivate. Unsure about drying time? If you're not sure how long it takes for the product to dry, it's always a good idea to wait about 24 hours.

                  I used this product in conjunction with expensive 12 ounce Ortho Orthene Fire Ant Killer (the white smelly powder stuff). Per the directions, I first applied the white powder to the mound, then I applied these Ortho 3 lbs Fire Ant Killer Mound Treatment granules as directed, then I watered the two poisons in to penetrate the mound as directed. The result is a higher kill rate result than when either of these products by themselves, and I did treat all of my property as directed. It does kill all of that mound location, but new mounds do appear, I do know that it is a myth that "if you kill the queen you kill the colony", the truth is that ants cannot eat a solids they can only digest liquids. When you dig into an ant mound you will see larva creatures living down in the mound. It is the job of these larva ants to digest the solid foods brought in by the workers and they convert it into a liquid that feeds the whole colony. So if you kill all of the larva ants, the entire colony starves to death (that is how ant bait poisons work, the problem with baits is that if it rains the poison coating washes off leaving only the food, plus the danger to pets). What I don't know is whether the eggs that I see in the mounds survive this poison and then hatch and form new mounds. Regardless, though this is not a one-time cure for fire ants, but my above described procedure gave me the best results that I have ever been able to get.

                  It does what it says, period.
                  [This review was collected as part of a promotion.] Ortho Fire Ant Killer Mound Treatment does exactly what it says. I was very carefully to follow the directions. I made sure I didn't apply a single grain on the mound. The ants vacated within the allotted time. In 5 mounds I found only one ant. I liked the way the directions explained in detail how much & where to apply the product.

                    I cannot live without this product. Here in SW Florida these fire ants are very MEAN and this stuff kills them fast. I make sure I do not get low on this product, always have a spare bag.
