Why are there so many flies on my artificial grass?
Flies and gnats gather on artificial grass because there is pet-waste residue or decaying organic matter in the infill for them to feed and breed on, usually in the damp, shaded parts of the yard. The fix is removing the food source: pick up solids daily, flush and enzyme-treat the pet zones, power-brush and rinse the organic layer out of the infill, and sanitize. TIMELESS Turf Restoration does this as part of a Premium Restoration across the Grand Strand.
What they are feeding on
House flies and blow flies come to pet waste, fresh or the residue left after it has been picked up. Fungus gnats and drain flies breed in wet, decaying organic matter, which is exactly what pollen paste and leaf litter become in damp infill by midsummer. If the flies cluster over the dog's spot, it is waste. If the gnats hang in the shaded strip by the fence, it is organic buildup. Both mean the infill has a food source in it.
Why sprays fail
An insecticide kills the flies present and does nothing to the residue. The next generation hatches or arrives within days. The only fix that holds is removing what they are there for.
The fix
Daily pickup. Then a proper odor treatment of the pet zones, which digests the residue with enzymes, and a deep clean that power-brushes and flushes the organic layer out of the rest of the yard. An antimicrobial finishes it. Yards with a persistent gnat problem in the shade usually also have algae, and usually also have a drainage reason the strip stays wet, which we point out.
