Barrier of Death
This poison is crazy powerful. Any roach/insect that makes across the barrier has not lived more than a few inches once crossed. It is POISON and does not discriminate between fire ant, cockroach, cat, child... so take care where you lay your barrier.

OMG 🤗with a huge WOW…
Orthene is most definitely thee best product to eliminate the fire ants/ black sugar ants and the small roaches. I also have the liquid gallon spray. I'm speechless at the results so I had to share it for others with a pest issue cuz no matter how clean I keep my home they still find a way to get in. For faster results mix with sugar, place in small pieces of foil, bottle tops or cut up a paper plate. If you have small children please place completely out of sight. Also mix %26 place when kids aren't home because the powder one has a strong smell which will subside after about an hour. Please read the instructions thoroughly.

I saw someone on TikTok using it for roaches and tried it. Let me tell you, IT WORKS for me! What I didn't like was the smell, I felt like I was going to vomit. Within two weeks all gone.
