They look like black poppy seeds and are about the same size. Juvenile mites are much smaller and more brown in color. Mites like to hang out in the nook and cranny areas such as eye corners, under the jaw, under scales, and in heat pits. But they can be found crawling anywhere.
You can definitely feel them when running your hand down the length of a snake. Just feels like dirt rolling between.
And they burst like fleas when you pop them.
