Are skunks or raccoons digging up your lawn? Do you have large patches of dead grass? These are signs you have lawn grubs. Lawn Grubs are the larval stage of May/June Beetles, Japanese Beetles and European Chafers. Lawn Guardian consists of beneficial nematodes that are microscopic worms which are native to Canada. Lawn Guardian is a mix of two nematodes, one that is close to the surface approximately 3” and one that goes deeper approximately 7”. NIC nematodes are isolated Canadian Strains that are Produced by NIC in Ontario, on a live host. They are fresher, more keyed to Canadian pests and 100% organic.
In the spring (May) when soil temperature is 10C (50F) or warmer and grubs are seen in the soil. An application will stop grubs from damaging your grass roots. Apply in autumn (end of August to September) eliminating grubs thus preventing fall and following springs damage. Next years application should be in the fall.

Length of grass and nematode applications
How long should grass be when I apply the nematodes ? The grass needs to between 1 to 2 inches in length. The nematodes need to be easily washed into the soil from the blades of the grass.
Should grass be kept moist after the nematodes have been applied? Yes, the lawn should be wet for 3 to 4 day after the application. This allows the nematodes to find the grubs and start to control this pest.
How much time should pass before the grass is first cut after the nematodes have been applied? You can mow your grass the next day.
SPECIAL NOTES: Note: Beneficial nematodes are most effective when soil is moist and remains moist for 3 to 5 days after application. Lawn Guardian is easy to apply using a hose-end sprayer and comes with full instructions.
Application of 10 million nematodes should take approximately 40 minutes to apply using our hose end sprayer.
