Nematode Grub Management manages infestations of white grubs primarily caused by the European Chafer Beetle or Japanese Beetle (June Bug). This grub treatment can be purchased separately when insect problems are detected or suspected, however they are best used as a preventative! Grub treatment is always a separate service with most companiesn including LawnSaversn but can be included with either of our lawn care packages, and we will further discount the service for you with your program loyalty discount! If you’re looking for a grub control company in Toronto, you’ve come to the right place.
Purchase a “scarecrow” motion activated sprinkler to repel them from Lee Valley Tools or Lowe’s Canada.

LawnSavers has been utilizing cutting edge “Nematodes” a type of round worm, for years to naturally manage populations of White Grubs in your Soil. There are literally thousands of species of Nematodes in the world, but oly a few known to be helpful combatting against typical turfgrass damaging grubs and insects.
Nematodes are only successful at managing grubs when the grub larvae are very young. In the Greater Toronto Area this means that applications are best suited for approximately late August through Early October (check with your LawnSavers professional). All university trials in our local climate show very little control when applied in the Spring, so be careful what your retailer, supplier, neighbour or lawn care company is claiming, you could be wasting your money! (the grubs are too large and lethargic to be innoculated and die before pupation sets in. The soil temperature at the habitation level must be at least 12-15 deg C. or they will not infect their hosts. Nematodes will have no effect on pupating larvae! (research By Dr. Michael BrownBridge (Vineland Research) and Pam Charbonneau (OMAFRA))
NEW & PROMISING: Steinernema glaseri: These are being studied to possibly one day being used to control late stage grubs in the spring. This species is one of the largest entomopathogenic nematode species and they measure at about twice the length of Steinernema carpocapsae and eight times the weight. Steinernema glaseri has been found to be effective against coleopterous larvae, particularly scarab beetles. This species is a cruiser, neither nictating nor attaching well to passing hosts, but highly mobile and responsive to long-range host volatiles. Thus, this nematode is best adapted to parasitize hosts possessing low mobility yet still living within the soil profile. Field trials, particularly in Japan, have shown that S. glaseri can provide some control of several scarab species. It’s large size, however, reduces yield, making this species significantly more expensive to produce than other species. A tendency to occasionally “lose” its bacterial symbiote is also a challenge. Moreover, the highly active and robust infective juveniles are difficult to contain within formulations that rely on partial nematode dehydration. In short, additional technological advances are needed before this nematode is likely to see substantial use. University of Guelph’s turfgrass institute is conducting ongoing field trials to test efficacy before we can safely say that it will have a marketable effect on scarab beetles in the Spring.

Heterohabditis Bacteriophora is the newer strain of Nematode that is the ideal predator of the European Chafer Beetle larvae. At LawnSavers we apply these at a much higher rate in order to increase the likelihood of infection in the grub and to increase the likelihood of a better kill.
Proper storage and application of your nematodes is critical in order to have any success- These creatures are EXTREMELY temperature sensitive. These living organisms usually die after 30 days. They MUST be stored in a refrigerated environment. They can not be subjected to freezing or heat. LawnSavers orders our Nematodes on a weekly basis, has them shipped in climate controlled containers, and use our supply within 5 days in order to ensure freshness and viability of the nematode.
