    Hey Dave, Good question. The active ingredient in Ortho Orthene Fire Ant Killer is Acephate. Acephate is a systemic insect control that kills by contact meaning the insect must come in contact with the product It affects the insect nervous system. Orthene Fire Ant Killer is a powder which the worker fire ants will walk through, tracking the powder into and throughout the mound to the queen. If you have additional product questions or concerns, please do not hesitate to reach out at 877-220-3089. We're here to help!

      When I apply Orthene as directed the product blocks the nest entrance at the center of the mound. Should I poke through the product to reopen the entrance or leave the product alone and let the ants dig through the product to reopen the entrance?

      Answer This Question

      Hello Tim and thank you for your question! Orthene Fire Ant Killer is a powder that worker fire ants track into their mounds, reaching the queen. For Orthene Fire Ant Killer to be most effective, the ants need to be active and the mound undisturbed, ensuring the worker ants unknowingly carry the product into the colony.

            Ants made a nest in and around my flowering plants in my garden. Can I put ortho ant killer around these plants

            Answer This Question

            Ortho Orthene Fireant Killer1 can be used around flowers, trees and shrubs. The product can be used around and up to the base of the plant, but is not registered for use on plants and should not touch the foliage of plants. If the product is accidentally applied to plants, wash them off with water.

              Answer This Question

              When used according to label instructions, Ortho Orthene Fire Ant Killer1 poses no unreasonable health risks. At a minimum do not allow pets such as cats and dogs and other non-grazing pets into treated area until dust from applying has settled. For best results keep pets such as cats and dogs and other non-grazing pets out of application area for up to 24 hours so that the mound is not disturbed. This allows the ants to track the powder into the mound to effectively kill the ants in the mound, including the queen.

                    [This review was collected as part of a promotion.] The bottle is easy to open and use. The concentration is good. I like that it’s safe for the environment. I didn’t notice any residue. But the smell is very off putting. Fire ants don’t stand a chance.

                      Good priced…
                      [This review was collected as part of a promotion.] I received this ortho ant killer in exchange for my honest review So love how clear the label it the ease at opening it and the bottle is sleek, however that’s about it for me… It smelled horrible when I opened it it blew up at me glad I did it outside. I sprinkled it on gave it its time and still just ants for days. Also huge pain had to chaperone the dog make sure she and none of the kids went over there I get it’s a killer but ugh. I might give it another try I’ll update if it changes my mind. It is got a good price I guess

                        Smelly but effective.
                        [This review was collected as part of a promotion.] I have a few red ant mounds in my mulch beds below my plants. I’ve noticed an increase in red ants in the porch since my plants have been planted and are growing. They love crawling around in there… I don’t care for them much. Using this product I’ve seen a slight decrease in red ants on my porch now, they are still there but not as many. The product is easy to open with the help of the lid notch, just read the directions. It has a unique smell that I’m not a fan of, but I’m sure it’s helpful to the ants. I sprinkled I’d say maybe a teaspoon over the mulch where the ants are but it looks a lot. The whiten powder can’t deter people from touching and staying away. When using I suggest wearing gloves and a mask. There is a lot of dust kickback.

                          Don't Believe the Label, Sounds too good to be true.... It Probably Is.
                          I have purchased both Ortho Orthene Fire ant Powder and Bag of Granules. I spot treated the mounds and then broadcasted the bag in the entire treated area. All the ants did was move from the current mound location to one to two feet away and make another mound. I then treated the Mounds as directed on the Label only to find another several new mounds within two foot diameter of the original mound. This product is not worth the time.

                            Great product for stopping pesky ants!
                            [This review was collected as part of a promotion.] This worked really well to stop the ants from coming into my home. The small container makes it easy to store. The thin powder texture allows for deeper penetration of the ant hill. Definitely worth the price!

                              This stuff works wonders. Have no idea what is in it and it has a strong odor. After sprinkling this doom powder on the ant hill and checking the next morning there was no activity. It zapped every ant in that hill I am totally impressed by the excellence of this product. No more fire ants.

                              This works very well to keep fire ants under control. I keep a bottle of orthene fire ant killer on my riding mower. While mowing when I see a fire ant mound, I treat it immediately before I lose track of where it is located. What I don't like is that it smells really bad, and it is very very white. I wish it was a color that doesn't stand out so vividly.

                                Difficult to open safety lid
                                This container has a yellow lid that must be squeezed on two sides to open, much like a medication bottle. However, it is very difficult to do so. In fact i was not able to get the lid to rotate no matter how hard i squeezed. I had to return all that i purchased due to this difficulty and have contacted the company. My hands a fairly large and i play racquetball and other sports. Its not a question of strength but of design.

                                Hi Chris! We're so sorry to hear you're having trouble opening the Ortho Orthene Fire Ant Killer. We want you to have a great experience with our products, so let's get this sorted out.

                                To open the cap, turn it counterclockwise until the cap locking tab reaches the locking tab on the container. Once in this position, the cap will stop turning counterclockwise. Then, squeeze the cap only in the spots that say "squeeze hard" using the slightly raised grip spots on the lower portion of the cap. Squeezing only in these two positions will change the shape of the cap to more of an elongated oval, allowing the locking tab on the cap to bypass the locking tab on the container.

                                We're confident in our products and offer a product guarantee. If, for any reason, you're not satisfied with the results after using this product, you're entitled to get your money back. Limitations apply. If you need further assistance, please don't hesitate to reach out to us at 877-220-3089. We're here to help! ortho
