And it is likely that it doesn't stop the infestation because many if not all insects have become resistant to pesticides. And chinch bugs fall into that category. The overuse of pesticides and other lawn care products have made it increasingly difficult to control insects. When I was a kid, and playing baseball and football ,the fields were all in pretty good shape. No one used lawn care products.
The lawn care industry has made billions by convincing home owners that they need the perfect lawn. Do you honestly think the lawn care companies are producing top of the line products?? The answer is no they are not. They are producing products that barely work for the most part because they want home owners to continue to purchase their products in the hope that the lawn will look better. It's all one giant con game.
