If you’re faced with a grub infestation, and you don’t want to use a chemical pesticide, turn to Mother Nature instead! Beneficial nematodes are small microscopic worms. They are mixed in with water to wake them up and sprayed on grass. Once in the soil, they search for a host, which is usually a grub. The nematodes carry a pathogen that they inject into the host grub, and that pathogen multiplies and kills the grub within a day or two. Then the nematodes lay their eggs on the dead grub. New babies go out and search for more. Mother Nature comes through again.

In general, treat when larvae are present and actively feeding, in late April until mid-June and again in early August through October.

Best applied when lawn is wet. Time applications around rainy periods or water lawn prior to application.

Step 1
Remove sprayer lid.

Step 2
Open nematodes globe and place the pouches in the sprayer. To avoid clogging the sprayer, do not tear or open the pouches when placing into the sprayer.

Step 3
Activate nematodes by adding about 2.5 cm (1 in) of warm water in the sprayer. Activated nematodes are sufficiently small so that they will pass through the mesh of the pouches.

Step 4
Add room temperature water to fill sprayer bottle.

Step 5
Fasten lid securely and shake vigorously to evenly disperse nematodes. Nematodes are sufficiently microscopic to flow through mesh of the pouches.

Step 6
Attach garden hose to sprayer and turn valve to “Mix” position to begin spraying.

Step 7
Start spraying in most affected area of lawn first and complete spraying outwards to provide total nematode coverage. Agitate spraying solution often during application because nematodes are heavier than water and will sink to the bottom of the bottle.

Step 8
Keep lawn moist for the next 3 days (or 1 week in dry weather) to ensure nematodes are flushed into the turf canopy where grubs are present.


Tips

  • Treat when larvae are present and actively feeding, in late April until mid-June and again in early August through October (varies slightly by geographical location).
  • Apply nematodes to lawns when the soil temperature is between 10 °C and 30 °C (50 °F - 86 °F) and water lawn copiously in the following days.
  • Apply to soil in the early morning or evening to avoid heat and direct sunlight.
