It does not bring levels to mix, it just says to pulverize the mounds of ants and plants, and not to water for the moment. I make the mixture of 2/3 teaspoon in a gallon of water with some soap?
Try googling the manufacturer's website to see if you can find any more information. I would not want to guess on the correct levels. If the website doesn't help, try searching on "Orthene wetable powder"
