Query: Holy hell, does this stuff work!

So the other day I was minding my business tree-trimming, when 15-20 red ants thought it would be a smart tactical move to crawl onto my feet and let slip the dogs of war. Well, they won that battle but thanks to this product, they lost the war.After hosing off my feet and applying liberal amounts of calamine, I fired off an order for some of this well-reviewed ant poison. I received and applied it Tuesday night, and went to check results Thursday morning, 36 hours later.The nests are annihilated. Completely dried up, devoid of ant life. Ghost towns. I missed one nest, it was still full of ants, but every single mound I poisoned is 100% dead. I call that pretty effective. I am rarely impressed this much with the effectiveness of a product. If you have fire ants and want them to die a near-instant chemical death, because that's what the get for being jerks, this is the weapon of choice.
