Nematodes

Controlling Lawn Pests Naturally

 Nematodes are naturally occurring, microscopic worms that are applied to lawns for control of White Grubs.  They infest and kill their prey within 24 – 48 hours and take 7 – 21 days to clear the area. They continue to reproduce, with the young seeking out new pests to infest.

 When do I apply Nematodes?

Apply Nematodes as soon as possible after purchase during rainy, overcast weather.  Nematodes are sensitive to sunlight and temperatures below 13C.

 Apply when insects are actively feeding with a hose-end-sprayer.

How do I apply Nematodes?

Before applying, water your lawn thoroughly (or apply them during/after a rainfall).

 

  • ·        Nematodes are stored on a damp sponge that covers 3,000 Sq. feet.
  • ·        Place the sponge into the hose-end-sprayer and fill with water, shaking vigorously for 15 – 30 seconds.
  • ·        Attach garden hose to sprayer and turn on valve to begin spraying.  Start spraying in most affected area of lawn first and complete spraying outwards to provide total nematode coverage.
  • ·        After application, water for 30 – 45 minutes

 To optimize performance: Water 30 – 45 minutes each day for the next 3 days to ensure nematodes are flushed into the root zone, where feeding grubs are present.

 Other Facts: If your coverage area is less than 3,000 Sq. feet, you may apply the remaining solution to vegetable and flower gardens.
