PEST CONTROL
Fly Control in Toronto & the GTA
From fruit flies to cluster flies to commercial drain fly issues — we identify the breeding source and eliminate the problem. Critical for restaurants, food processing, and storage facilities.
OUR APPROACH
How We Eliminate Flies
Find the Breeding Source
Fruit flies, drain flies and cluster flies breed in completely different places — fermenting organic matter, the biofilm inside drains, and outdoors in soil respectively. Identifying which you have decides everything else.
Eliminate the Source
Treatment without removing the breeding medium fails within days. We locate and address the source — a forgotten drain, a cracked floor gully, organic buildup under equipment — rather than only killing adults.
Treat and Monitor
Residual treatment and monitoring at the source area, which for commercial kitchens also means documentation suitable for a health inspection.
How to Identify Flies
Fruit flies are small and tan-to-black, drawn to ripening produce and drains; cluster flies are slightly larger, slow-moving, and overwinter in wall voids; drain flies are fuzzy and moth-like and breed in the gel-like film inside slow drains. The species usually points directly to the breeding source.
Seasonal Behaviour in Ontario
Most indoor fly problems trace back to a specific breeding site rather than flies simply entering from outside — a piece of overripe fruit, a dirty drain, or organic debris in a garbage disposal can sustain a population indefinitely. Cluster flies are the exception, entering in fall to overwinter and becoming active again on warm days in late winter.
DIY or Call a Professional?
Removing the breeding source, ripe produce or a dirty drain, resolves most small fly problems within days. Flies that persist after the obvious source is addressed, or a sudden appearance of flies in commercial kitchens or food storage areas, usually mean the breeding site hasn't been found yet and is worth a professional inspection.

COMMON QUESTIONS
Fly Control — Questions We Get
Why do fruit flies keep coming back after I clean?
Because the breeding site is usually somewhere less obvious than the fruit bowl — the biofilm inside a floor drain, a gap under a dishwasher, a recycling bin, a mop bucket, or a slow leak under a cabinet. Fruit flies complete a generation in about a week, so any missed source repopulates quickly.
What are the flies swarming my windows in autumn?
Almost certainly cluster flies. They breed outdoors in soil, then move into wall voids and attics in autumn to overwinter, emerging on warm days at south and west-facing windows. They are not a hygiene problem and do not breed indoors, but the numbers can be considerable and exterior treatment before they enter works far better than treating inside afterwards.
