Finding the source.
From Moreno Valley out to Riverside and San Bernardino, trash bins in summer are the usual culprit. Likely a dead animal. Bad smell plus big shiny flies?

If something died nearby.
Follow the smell and the flies. Wear gloves, bag it, and disinfect the spot. A wall may need a small hole opened. The flies stop once the source is gone.
