Pest & Grub Control in Saint John, New Brunswick

Saint John, New Brunswick's largest city with a population of approximately 130,000 in the metropolitan area, sits at the mouth of the Saint John River on the Bay of Fundy in zone 5b. The city is influenced by the Bay of Fundy — home to the world's highest tides, with a tidal range exceeding 14 metres — which creates a unique coastal microclimate with cool, fog-prone summers and relatively mild winters for the latitude (-8°C January average). This maritime influence extends the shoulder seasons but can delay spring warm-up compared to inland communities.

Local Lawn Care Conditions

Saint John's heritage Uptown district features Victorian-era row houses and brownstones with small but visible front yards where maintenance quality directly affects the streetscape. The city's residential areas include the established south-end neighbourhoods near Rockwood Park (the largest urban park in the Maritimes at 890 hectares), the Millidgeville waterfront, and the suburban communities of Rothesay and Quispamsis in the Kennebecasis Valley. The University of New Brunswick Saint John campus and the Saint John Regional Hospital are notable institutional properties. New Brunswick's Cosmetic Pesticides Ban Regulation prohibits cosmetic pesticide use on residential lawns. The city's soils tend toward acidic (pH 5.5 to 6.5), and the high humidity and precipitation (approximately 1,400 mm annually) create favourable conditions for fungal lawn diseases.

Our Pest & Grub Control Service

White grubs are the single most destructive lawn pest across Canada. These C-shaped larvae — the immature stage of European chafer beetles, Japanese beetles, and June beetles — feed on grass roots just below the soil surface, severing the root system and causing irregular brown patches that peel back from the soil like loose carpet. A secondary damage layer comes from wildlife: skunks, raccoons, and crows tear up grub-infested turf to feed on the larvae, often causing more visible damage than the grubs themselves.

How It Works

At Mow.ca, our pest and grub control programs use an integrated approach combining biological controls, cultural practices, and targeted treatments that are effective while being safe for children, pets, and the environment. Our primary biological weapon against white grubs is Heterorhabditis bacteriophora — a species of beneficial nematode that actively seeks out and parasitizes grub larvae in the soil. These microscopic roundworms are applied as a liquid drench in late August to early September, when soil temperatures are above 15°C and newly hatched grubs are small and most vulnerable. Nematodes are a registered biological pesticide that is exempt from provincial cosmetic pesticide bans and safe for use around people, pets, and waterways.

For properties where nematode application alone may not achieve sufficient control, we also offer Bacillus thuringiensis galleriae (Btg) — a bacterial biological insecticide registered by the PMRA for use against white grubs in turf. Btg works by producing proteins that are toxic to grub larvae when ingested, but harmless to mammals, birds, and beneficial insects.

Why Choose This Service

Beyond white grubs, we also treat for chinch bugs (Blissus leucopterus), which damage lawns by sucking sap from grass stems and injecting a toxin that causes yellowing and death. Chinch bug damage is most severe in hot, dry conditions and often mimics drought stress. Our treatment approach for chinch bugs includes Beauveria bassiana (a fungal biocontrol) in provinces with pesticide restrictions, and targeted insecticidal applications in unrestricted provinces. We also address sod webworms (Crambus spp.) and European crane fly larvae (Tipula paludosa) — the latter being a significant pest in BC's Lower Mainland.

Grub inspection is included with every pest control visit. Our technicians perform a pull-test by lifting a one-square-foot section of turf in suspected areas. The treatment threshold is five grubs per square foot — below this level, healthy turf can typically tolerate grub feeding without visible damage. Above this level, treatment is recommended.

Pricing & Scheduling

Pest and grub control pricing ranges from $75 to $180 for a standard residential lot, depending on the pest type, treatment method, and property size. Nematode applications are typically at the higher end due to the cost of live biological product, but they offer the most environmentally responsible control with no re-entry restrictions — your family and pets can use the lawn immediately after application.
