With Oakville, Mississauga and Milton municipal pesticide banns in effect, beneficial nematodes are the most effective way to control cranefly larva, June bug larva (white grubs) and other turf damaging grubs in your lawn, including European Chafers and Japanese Beetle. White grubs and certain larva feed on the roots of grasses and in the spring when they have reached their maturity they hatch out of the ground and become Japanese Beetles, European Chafer and June Beetles. We want to eliminate as many grubs as possible to prevent them from maturing and coming out of the ground to damage trees, as well as to prevent the grubs from damaging the lawn. Nematodes are naturally occurring organisms that actively seek grubs and once found they enter the white grub release a bacteria in the grub which causes it to die. Nematodes will not harm humans, pets, wildlife, birds, soil, earthworms, water sources or the atmosphere. Nematodes arrive on a damp sponge within a plastic bag and are kept cold and dormant. To use, you soak the sponge in room temperature water and then apply the water to your lawn or garden using either a watering can or hose-end sprayer. The application is not difficult, but the timing is important. You need to apply in mid-May to mid-June, while the grubs are still in their larvae stage. Cool and cloudy late spring weather when frost danger has passed is ideal. The second application is from mid-August to mid-October. Please give us a call or drop by if we can help with your grub problem or nematode application.
