I don’t know what kind of bug I have in my yard but when I’m pulling up weeds out come thousands of small flea type bugs but I’m not sure they’re fleas. I live in the upper desert.
We’re in New York so I’m not to familiar with insect pests of the high desert. It may be that you have Sand Fleas but, with out see one it is just an educated guess. I’d suggest capturing some and brining them to a local garden center for a more accurate ID.
