We have many spots that are growing yarrow. How do we get rid of it and still be safe for small pets?

Common yarrow can be quite invasive and difficult to control. They spread through roots, making it a plant that needs to be dug up. I would recommend digging up as much as you can, then applying either Round-up or boiling water to the area where it was, to kill off any of the remaining roots. Be aware that both Round-up and boiling water will kill whatever plant growth it touches.
