I had a serious ant 🐜 problem. I'd been using product from garden centres but the little expletives thrived on them. Not now, I've turned into a mass murderer.I know this stuffs expensive but compared to the cost of replacing a brick path or drive its nothing. And, I've still got half a container left for new infestations. ### ⭐⭐⭐⭐ It's good *by on Reviewed in the United Kingdom 12 August 2025* It's good ### ⭐⭐⭐⭐⭐ Ant killer for grass *by on Reviewed in the United Kingdom 9 July 2026* Excellent, effective and would buy again. ## Frequently Bought Together - Karlsten Ant Killer Spray 5L – Extra-Strong Cypermethrin Formula for Indoor & Outdoor Use – Fast-Acting, Long-Lasting Pest Control – Kills Red & Black Ants, Stops Infestations - NOPE!
