Fight Japanese Beetles at the Source with Nematodes!

Japanese beetles have become a serious problem in southwestern Ontario. Japanese beetles can quickly turn your ornamental plants and thriving lawn or garden into a chewed-up mess. Thankfully you don’t need harsh chemicals to take control. We are pleased to offer Lawn Guardian, a natural, Canadian-made solution that targets beetle larvae right in the soil before they emerge. By applying beneficial nematodes at the right time, you can stop the damage before it starts and protect your green spaces the eco-friendly way.

Lawn Guardian contains a targeted blend of beneficial nematodes—microscopic, soil-dwelling organisms that act as natural predators to turf-damaging pests like Japanese beetle grubs. Once applied to moist soil, these nematodes actively seek out and infect pest larvae, ultimately breaking the life cycle before the adult beetles can emerge. It’s a highly effective, chemical-free way to protect your lawn—safe for people, pets, pollinators, and the environment. The nematodes are applied to the lawn and gardens by using a hose end applicator.

The best time to apply Lawn Guardian is in early fall. Additionally nematodes can be applied in the spring, just be sure to wait until the soil temperature has reached atleast 10 degrees.  In the fall Japanese beetle larvae are newly hatched and actively feeding near the surface of the soil—making them most vulnerable to nematode attack.

For best results:

• Apply in the early morning or evening when temperatures are cooler.

• Ensure the soil is moist before and after application to help the nematodes move through the soil.

• Avoid application during hot, dry conditions or direct midday sun

By disrupting the life cycle of the beetle you can significantly reduce the beeltes in your yard and the damage they cause using safe, environmentally friendly nematodes!
