    • Wow! Works GREAT!
Size: 2 - 12 OZ Bottles Style: Mound Treatment
This ant killer is fantastic. A mound pops us, you give it a good coating with this powder and it pretty much kills on contact. We live in Oklahoma and last year, I got bitten by one too many fire ants. This year, it's personal. I have already eradicated three mounds and am ready to do battle with any others that try and take root. Be mindful to stand downwind because this stuff stinks! Bad. But it absolutely gets the job done. Highly recommended. ... show more

I recently used Ortho Fire Ant Killer Mound Treatment, and I must say, it exceeded my expectations in every way! Living in the South, fire ants have always been a persistent problem in my yard, and I’ve tried several products over the years with mixed results. However, this one truly delivered fast and effective results. Effectiveness – Quick and Long-Lasting One of the best things about this product is how fast it works. After sprinkling the granules directly onto the mound as directed, I noticed significant ant activity reduction within hours. By the next day, the mound was completely inactive! This treatment doesn't just kill ants on the surface—it goes deep into the colony, wiping them out at the source. The best part is that it offers long-lasting control, so I don’t have to constantly reapply it. Ease of Use – Simple and Mess-Free Another huge plus is how easy it is to use. The granules come in a convenient, resealable bag, making application simple and mess-free. Just sprinkle the recommended amount on the mound and lightly water it—there’s no need for complicated mixing or additional steps. Safety & Residue I also appreciate that this product is odor-free and doesn’t leave behind any unpleasant residues. It’s safe to use around the yard when applied correctly, and I didn’t have to worry about any lingering chemicals affecting my pets or garden. Value for Money Compared to other fire ant killers I’ve tried, Ortho Fire Ant Killer is a great value. A single bag covered multiple mounds in my yard, and since it works so effectively, I didn’t have to keep reapplying, which saved me both time and money. Final Verdict – Highly Recommended! If you’re dealing with fire ant problems, Ortho Fire Ant Killer Mound Treatment is a must-have. It’s fast-acting, long-lasting, easy to use, and provides excellent value for the price. I’ll definitely be keeping this on hand for any future infestations. Highly recommend! ⭐⭐⭐⭐⭐ 5/5 Stars! ... show more

    • Ortho Orthene Fire Ant Killer: Because Your Yard Deserves to be a Fire Ant-Free Zone
Size: 2 - 12 OZ Bottles Style: Mound Treatment
Fire ants, huh? The little buggers that turn your backyard into a battlefield. You’re just trying to enjoy your Sunday BBQ, and suddenly, BAM, you’re fighting for your life against tiny red demons who seem to think your feet are their personal target practice. Well, guess what? Ortho Orthene Fire Ant Killer is here to save the day, and it’s not playing around. This stuff is like the fire extinguisher of the insect world, except it works faster and is much better at not causing fires. Let’s break this down: Ortho’s got a secret weapon, it starts working in 60 minutes. That’s right, in the time it takes for you to binge-watch one episode of The Walking Dead, this stuff is already in action, tearing through fire ant colonies like it’s a one-man wrecking crew. And not just the worker ants, oh no. It goes straight for the queen too, because if you want to stop the operation, you go straight to the top, right? Think of it as a tactical strike on the entire fire ant empire. And don’t worry about messing around with complicated instructions. Just sprinkle this 12 oz. of fire ant-fighting magic on the mound and sit back while the ants get their eviction notice. If you’ve got a serious fire ant issue, grab the 2-Pack, because you’re going to want backup. PROS: • Kills the queen: It’s like a game of Ants vs. Us, and guess who’s winning? You, with the queen gone and the rest of her minions scrambling for survival. • Starts working in 60 minutes: It’s like a turbocharged anti-ant missile. If ants had feelings, they’d be seriously bummed right about now. • Easy to use: Just sprinkle it, and BAM, instant karma for the ants. No complicated steps, just results. • Kills mounds: If you’ve got a yard full of fire ant mounds, this stuff is like a party crasher, coming in and taking down all the invitations before they can even spread. • Effective: It works like a charm. If only we could get it to work as quickly on other pests, like that guy who always parks too close to you at the grocery store. CONS: • You might need more than one application: If you’ve got a major infestation, you might need to go back for seconds. But hey, ants aren’t known for being smart. • Can be a little dusty: A small price to pay for watching those pesky ants disappear into oblivion. In short, if you’re tired of feeling like the fire ant king’s personal doormat, Ortho Orthene Fire Ant Killer is the hero you’ve been waiting for. It’s quick, effective, and gets straight to the point. You’ll be able to enjoy your yard without worrying about fiery critters popping up like uninvited guests. Consider it your personal fire ant bodyguard. Because who doesn’t want that kind of protection? ... show more

Our apartment got infested when a neighbor in another apartment moved out. We tried the advion cockroach that's really popular and for awhile it seemed to work until we noticed some were just evolving. This powder took them out! It smells horrible! I can guarantee you that, open all the windows, wear a mask... however you won't see not one roach after giving this a try. 2 months ago wedeepcleaning under all appliances, sprinkled this there and everywhere in our apartment even under the couch. We now haven't seen not one of them pesky things anywhere!! ... show more

    • Great! could deter anything with the smell!
Size: 2 - 12 OZ Bottles Style: Mound Treatment
This product works great but STINKS! It smells like someone farted on my lawn. I'd leave too if I was an ant. We had 3 hills located in different areas on the front lawn and for about a week it smelled like someone crop dusted my yard. The ants are gone though.
