Review: KILLED ROACH INFESTATION IN 3 MONTHS - This is the solution to your roach problem!!!! When i moved into my home it already had roaches and we couldn’t get rid of them for literal YEARS. I saw this recommended to me on tiktok and tried it out not expecting much. I poured the powder in places like under the fridge, crevices where i’d find roaches, by doorways on the outside, and around the garbage can in the kitchen. In the span of 3 months.. the roaches completely disappeared. More and more were found dead. They love this stuff because it smells like literal garbage. If you want to attract them more you could pour some sugar alongside the powder. It also stopped ants from coming in during the summertime so that was a huge plus. Yes this powder is made for ants, but it works wonders on roaches, even better than their dedicated roach killer.
Review: Buy it it works!! - 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.

## Questions & Answers

**Q: will this work to get rid of crawdads**
A: YES, it will.  I'm sure you're referring to the pesky lawn/yard crawfish that live underground and create mounds after every hard rain.  It's a real pain in the butt to have to remove the mounds before cutting the grass.  Either dump a little down each hole and add some water or mix it in a bucket with some water and pour a little down each hole.  It's time consuming, but eventually they will be gone.  I'm not sure if it kills them or just chases them off.  I tried it after reading online that one of the ingredients works on crawfish.

**Q: Why will this state that it will not ship to my address in Texas, however, no problem with the shipping of the same product that is in the 4 lb size?**
A: Everything in Texas is bigger? So you need the Taxas size

**Q: Does this kills roaches?**
A: Heck yeah it kills roaches! Within one hor of application, I started seeing them come out of hiding and die. You want to appy a light puff of the powder along the baseboards and wherever else you think they may hide. Don't put too much though, its not necessary. Vaccum it up the next day if you want and apply again for atleast a week straight. Yes,, product smells like boiled cabbage, but who cares, its worth it. I applied this for a single week, and didn't see another roach for 3 years!! And when I did, I applied the powder again for a day and quickly took care of the problem.

**Q: What happens if you disturb the mound?**
A: I have used this product for a long time.  I find it works fastest if I DO disturb the mound slightly.  I put a small amount of the ant killer on the mound. then I poke the mound a few times with a stick about 2 feet long.  Then I stand back!  The ants go crazy and carry the poison into the mound.  Just be sure to STAND BACK!!!!!!

### ⭐⭐⭐⭐⭐ Ortho Orthene Fire Ant Killer: Because Your Yard Deserves to be a Fire Ant-Free Zone
*by Z***R on December 14, 2024*

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?
