Lets talk about the dry herbicides and insecticides that you may apply to your yard and the effect of moisture on them. We talked about the effect of a rain coming on top of a liquid application that you might use as a fluctuant to stop the product from washing away. Dry products can have the same trouble because in order for them to activate, like this particular product has deltamethrin in it which is a real effective fire ant control and fleas and cinch bug control in the yard. It's going to take moisture to activate this insecticide. But very few people, when they do the application can guarantee that they're going to get enough water to activate the product and therefore it's watered in with a sprinkler system. Now sprinkler systems can apply very nice slow precipitation to the area to give the activation that is required for this herbicide. But you want to put controlled amount of water on there. Probably a half inch no more to the area because if you leave it on all night, you activate the insecticide tor herbicide for a little while and then after that your washing it away. You may not have run off that comes out of your yard and goes down the gutter down the street but you may have leeching where as the water is infiltrating through the soil and going into the sub soil and taking your herbicide or insecticide with it and once it gets down beyond where the pests are, where the roots are, it's not going to do any good it's just going to go into the ground water at worst and be ineffective in the least.
