White grubs is the common name of the larvae of several beetles:

• Japanese Beetles
• June Bug or June Beetle (also known as May Bug)

Potato tubers are one of the things they like to eat. They make large, shallow holes in the tuber, and although they are still safe to eat, the potato won’t be good for storing.

Chickens love to eat these grubs, so let your chickens help you find them when turning soil.
