I had potted some garlic to grow recently, and yesterday when I lifted the pot to clean under it, the soil seemed to look like pest excrement, of some sort. Here is a picture. Can someone help me understand what this is and if I need to be concerned?

Thanks![enter image description here]1

They might be worm castings. They look similar to the ones in this picture. Maybe check the soil to see if you can find any worms, if you're concerned. They shouldn't harm the plants.

Alternatively, they could be from caterpillars, but it looks a little wet for caterpillars to want to venture there.
