I keep a flat spade in the truck and, “after the rain,” I peel back a 1‑sq‑ft patch — if I count 6+ grubs, I spot-treat with trichlorfon the same day and then water it in about 0.5" so it reaches the root zone. If temps are already under 50°F, I skip nematodes since they don’t move enough to be effective.
After the “recent rains,” I’ve had good luck doing a quick soapy‑water flush (2 tbsp dish soap in a 2‑gal pump sprayer over 1 sq ft) to scout — if grubs pop up, I hit those spots with H… bacteriophora nematodes at dusk and keep it moist for 3 days. Small caveat: if soil temps are under about 55°F, I switch to trichlorfon instead because the nematodes are sluggish.
