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 a blend of beneficial nematodes that are microscopic worms which are native to Canada. Lawn Guardian is a mix of two nematodes, one (SF) that is close to the surface approximately 3″ and one (HB) 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.
100% Safe for people, pets, plants and even earthworms.
The lower mainland In BC is considered a microclimate so if applying nematodes for chafer beetle in this area, the optimal application time is mid July to mid August. This is when the eggs have just hatched and the grubs are at their most vulnerable.

Helpful hints: 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 to water your lawn for nematode application?
Nematode need water channels to make it to the level of the grubs. The soil moisture needed for nematodes has been described well wrung out sponge. Another test our owner John has developed is the plug test. Dig down to the below the turf grab a handful of dirt make a plug in your hand, now when you open your hand if said plug falls apart you need to add water if it retains its shape there is enough water for the nematodes to hunt and survive.
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.
