How do we know that these products aren’t harmful to humans or wildlife?

The pesticide industry is one of the most highly regulated industries in the United States. Before a product is registered by the EPA, it must be rigorously tested for human health and environmental safety. This process can take up to 10 years and involve up to 120 different tests and studies. Today, manufacturers may invest as much as $150 to $185 million or more in product safety testing before a new pesticide ever comes to the market. These safety tests are required, designed and reviewed by EPA scientists and are conducted according to EPA standards.
