For herbicides/pesticides that have been applied, we recommend waiting about 1-2 hours, but you should always double check to make sure any product applied has dried before allowing children or pets around treated areas. Humans and pets should always remain inside during an application. The drying time for herbicides/ pesticides can vary depending on environmental factors. Before letting your children or pets out to roam the area where the chemical was applied, double-check to ensure the area is completely dry. It's important that you know that the products we use have all been carefully screened and are regulated by the United States Environmental Protection Agency.
