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.

Nematodes must be stored at consistently cool temperatures (refrigerated.) This makes them ineligible for shipping. Once nematodes arrive at Peter Knippel Garden Centre, we will assemble your order and contact you when it is ready for pickup.
