Is there a product or spray I can use to stop cockatoos ripping out my kikuyu grass lawn.

Hello Joe, unfortunately we don't have a product that will deter cockatoos from ripping out pieces of your lawn. If you have had recent rains or have deeply watered your lawn, it is likely they're taking advantage of worms that come closer to the surface for air, and should only be temporary visitors. There are some bird deterrent products on the market, but apologies we don't a spray in the Yates range to stop them ripping out grass.
