This stuff works so so good on the ant issues we have. For pretty extended amounts of time. Obviously eventually they will pop up somewhere else but overall great product. Just know going in it smells awful lol Read more

Works on German cockroaches even though it’s for ants

YulyFebruary 19, 2026✓ Verified purchase

I bought this product because I had German cockroaches in my kitchen and nothing else was working. Although it’s originally designed for ants, it worked really well on cockroaches. It comes with two bottles, and the powder is easy to apply; I placed it in cracks, corners, and behind appliances. It doesn’t have a strong odor and doesn’t leave sticky residues. Within a few days, I noticed much less activity, and it lasts a long time. It worked much better than other products I had tried. I highly recommend it if you want to control cockroaches effectively.

Ortho Orthene Fire Ant Killer: Because Your Yard Deserves to be a Fire Ant-Free Zone

Zoe MechlerDecember 14, 2024✓ Verified purchase

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? Read more

Buy it it works!!

Sabrina P.January 10, 2026✓ Verified purchase

Better than a exterminator a little is all you need. I purchased this for someone who was experiencing roaches entering their unit from a unsealed hole in the wall after having water pipes replaced. After putting this around the perimeter of their apartment in less than a week not another roach was seen ever again. It stinks when you first open it but not a lingering smell that remains. Just during initial palceing of the powder. but works!!!! Very effective roach eliminating. Easy to use. Read more

It actually works!

CadiJanuary 25, 2026✓ Verified purchase

I first put a small dose because I didnt realize how large the mound was, and had to poison them again. However, within a few days the ants were dead. You can see some of them piled up dead in the picture. Great product for pesty ants, very easy to use. I will say it does have a yucky smell, but it sure is worth it because of how effective this poison was. Read more
