Will this product harm pets if they eat the grass in the area it is applied?

Based on what you've stated I would keep them out of the treated area for a couple of days just to be safe.

We've been putting this product down for 3 years now and my dogs don't have any problems with this product, that is why it is great. Once it has been watered down, it goes to work. I can't really speak to the scientific facts of pesticide harms and effects, but my dogs and family have had no ill effects than before using this product.

Animals such as dogs and cats can reenter the application area after it has been watered in and been allowed to thoroughly dry. While we wouldn't recommend allowing them to consume grass in the area, when used as directed it will pose no unreasonable health risks to cats or dogs.
