Tiny white kernels in grass

Asked January 4, 2019, 1:46 PM EST

I’ve been finding tons of tiny white kernels in my yard. More concentrated under my oak trees. Some have an orange skin on them. But most are white. Any idea on what they could be? Thanks!

Thank you for your question. I can’t see these structures very clearly, but I wonder if, instead of seeds, they are oak galls, discussed in this Extension article: https://entomology.ca.uky.edu/ef408 You would see them on your oak tree’s leaves, and then they fall, and the insects inside them emerge in the spring. If you cut one open, you would see the developing insect. If this is what they are, they will not hurt the trees, and need not be treated. You might want to take a few into your county Extension office for a certain ID. Here is their contact information: https://campbell.ca.uky.edu Good luck!
