When battling with the life cycles of various lawn munching pests, it is imperative to apply beneficial nematodes in the Spring and Fall. We’re witnessing widespread damage to lawns in the Oakville, Mississauga and Milton areas and with our 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. Many people use the pheramone based traps to catch the adults, but you need the nematodes for the grubs that haven’t yet come above ground in their life cycle. 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 until application. To use, you soak the sponge in room temperature water, making a concentrate. Next, you apply the water to your lawn or garden using either a watering can or hose-end sprayer. It is important that your watering can or sprayer be free of chemicals that may harm the nematodes. The application is not difficult, but the timing is important. Ideally, you’ve already completed a first application mid-May to mid-June, while the grubs are still in their larvae stage. It is now time for the second application. Also, the forecast for the next few days is a wet one, which makes it a great time to apply nematodes. They need to be applied to a wet lawn and watered in daily to really soak into the ground. So, if mother nature can help out with this application, all the better. If you missed nematodes in the spring, don’t worry, it isn’t to late, but you should still do your fall application now or in the next few weeks.
