The reason small flies are so frustrating in Ontario is that killing the adults changes nothing. The larvae are growing in a hidden pocket of wet organic film somewhere in the Ontario building, and every day another batch of adults climbs out. Small flies rest on walls and ceilings near their breeding site, so where they gather is a clue to the source.
In Ontario, a thorough inspection often includes pulling a drain cover, lifting a floor mat or tipping a soda gun holster. Larvae live in the film that collects in those places.
The product is low-toxicity and food-safe when used as labeled, which is why providers in Ontario favor it for kitchens. It works on the breeding film, not the visible flies.
Any product used should supplement sanitation, never replace it. Providers in Ontario may use a light residual on resting surfaces or an aerosol knockdown for a large flush of adults.

Most fruit fly advice online repeats the same unsourced claims, so for Ontario homeowners the statements below are tied to specific surveys, studies and published cost guides, and each one says what it does and does not prove for a Ontario property. Ten to 82 percent of apartments were nuisance-positive depending on the building, across 19 low-income New Jersey properties monitored by Wang and colleagues in 2018 and 2019 and published in 2023; the study is a related indoor context, not a fruit-fly prevalence measure. Five point six percent of the 54 basements inspected by Bertone and colleagues in 50 North Carolina homes in 2012 had fruit flies, a small-sample presence figure and not a national infestation rate. Context for Ontario, not a local measurement: for restaurant operators, the finding cuts both ways: 61% of patrons in Orkin, a pest-control provider, undated, provider-sponsored surveys said they would keep eating fly-touched food, a stated intention, and not a fruit-fly-specific result. Keep this in mind while inspecting a Ontario home: fruit flies turned up in 29.9% of the 97 living rooms and other common areas inspected by Bertone and colleagues in 50 North Carolina homes in 2012, the highest room-level share in the study; it is a presence figure, not a national infestation rate. Before comparing Ontario quotes, note this: in HomeTeam Pest Defense's March 2022 online survey of U.S. homeowners ages 25–75, 76% reported a pest problem within the preceding year; the sponsor sells pest control and the sample size was not disclosed, so treat this as self-reported, not an infestation count. None of these sources surveyed Ontario specifically, so read them as national and regional context; the local facts that matter most are the ones an inspector documents at your Ontario property, meaning where activity is, what is attracting it and how it is getting in.
If the flies in your Ontario kitchen run across the counter instead of flying off, you likely have phorid flies, and that usually means a plumbing problem. Providers in Ontario treat that as a repair issue and will tell you what to open up. An inspection report listing every source gives kitchen staff a concrete cleaning map to follow.
DIY works for fruit flies more often than for most pests in Ontario: toss the ripe fruit, rinse the recycling, run the disposal, scrub the drains and set a vinegar trap. When that fails in an Ontario home, it is because the source is somewhere the list did not cover. Letting houseplant soil dry an inch deep between waterings starves fungus gnat larvae within weeks.
For Ontario homeowners the useful local fact is the semi-arid climate, which drives the seasonal pattern of fruit fly activity described on this page. Activity typically peaks in late summer and fall; year-round indoors. The takeaway for Ontario homeowners is to act in season and to have entry points and harborage checked rather than guessed at.
