Fly Control and Fly Extermination in Toronto
Seeing a few flies doesn’t always mean there’s an infestation. But when flies keep appearing, concentrate around certain areas, or seem to come back after you’ve cleaned and sprayed, there may be an underlying source that needs to be identified.

Flies Keep Coming Back? Find the Source.
Killing the flies you can see may provide temporary relief. It doesn’t necessarily address why they’re there in the first place.
Different flies are attracted to different conditions. House flies may be associated with garbage and decaying organic material. Fruit flies are commonly associated with fermenting food and liquids. Drain flies can develop in organic buildup inside drains, while cluster flies can enter buildings and remain concealed in wall voids and attics.
Our approach looks at:
- What type of fly you’re dealing with
- Where the flies are concentrating
- Possible breeding areas
- Food and organic waste
- Drains and moisture
- Garbage and compost areas
- Building entry points
- Hidden areas such as walls, attics and voids

What Type of Flies Are You Dealing With?
Different fly species can behave very differently. Identifying the fly helps determine where to look and what type of control approach may be appropriate.
House Flies
House flies are commonly associated with garbage, food waste and other sources of organic material. If they repeatedly appear indoors, identifying where they're entering or breeding can be an important part of control.
Fruit Flies
Fruit flies are tiny flies commonly attracted to overripe fruit, fermenting liquids, sugary spills and food waste. Because they reproduce quickly, a small number can become a persistent nuisance.
Drain Flies
Drain flies are small, fuzzy-looking flies often associated with damp areas and organic buildup. Simply killing the adults may not solve the underlying problem.
Cluster Flies
Cluster flies can enter buildings through small openings and remain concealed in wall voids, attics and other protected spaces before becoming active later.
Blow Flies & Bottle Flies
These larger flies can have a metallic blue, green or dark appearance. Their presence indoors can sometimes point to an underlying source such as organic material, waste or, in some situations, a dead animal hidden in a wall or attic.

Fly Control for Your Home
Flies in your home can quickly become frustrating when they seem to appear no matter how often you clean.
Relief Pest Control can help investigate recurring fly activity in:
- Kitchens
- Bathrooms
- Basements
- Garages
- Attics
- Living areas
- Around windows and doors
- Garbage and compost areas
- Other residential spaces
If you’ve been killing flies for days or weeks and they keep coming back, the next step may be finding the source rather than simply treating the visible insects. Request a residential quote today!
Signs You May Have a Fly Infestation
A single fly doesn't necessarily mean you have an infestation. Look for repeated activity and patterns that may point to an active source, breeding area, or entry point.
Flies Keep Appearing
If you're constantly killing flies but more appear shortly afterward, there may be an active source nearby.
Large Numbers of Flies
A noticeable increase in fly activity indoors can indicate a breeding or entry problem.
Flies Concentrated in One Area
Flies repeatedly gathering around a drain, garbage area, window, kitchen, or other location can provide a clue about the source.
Small Flies Around Drains
Repeated small flies around sinks, floor drains, or other damp areas may indicate drain-fly activity.
Flies Around Garbage or Compost
Organic waste can attract and support certain fly species, particularly when food material is readily available.
Maggots or Larvae
Finding larvae around garbage, decaying organic material, or other concealed areas can indicate an active breeding source.
Flies Around Windows
Large numbers gathering around windows may indicate that flies are entering from another area or emerging from concealed spaces.
Flies Returning After DIY Treatment
If spraying kills the visible flies but activity keeps returning, the underlying source may still be present.
Commercial Fly Control in Toronto
For a restaurant, food-service business, grocery store, warehouse, office or other commercial property, recurring fly activity can become a much bigger problem. Flies around food, customers, employees or food-preparation areas can create hygiene concerns and damage the appearance of a business.

- Restaurants & Food Service
- Grocery & Retail
- Offices & Commercial Buildings
- Warehouses & Industrial Properties
- Property Management

How Our Fly Removal Services Work
Effective fly control starts with understanding why the flies are there. Relief Pest Control follows a structured process to identify the source, address the infestation and reduce the risk of recurring activity.
Inspect the Property
We begin by understanding your concerns and examining the property for signs of fly activity, potential entry points and conditions that may support an infestation.
- Identify areas of activity
- Check potential breeding sources
- Look for entry points
Identify the Source
Different fly species have different breeding habits. We assess the type of fly involved and investigate where the activity may be originating.
- Identify the fly species where possible
- Investigate organic material and waste
- Check drains, moisture and concealed areas
Treat the Infestation
Based on our findings, we develop an appropriate treatment approach targeting the active fly population and, where possible, the conditions supporting it.
- Targeted fly-control treatments
- Traps or monitoring devices where appropriate
- Treatment designed around the property
Prevent & Monitor
After treatment, we provide practical recommendations to reduce conditions that may contribute to recurring fly activity and determine whether follow-up is needed.
- Food and waste management recommendations
- Entry-point and sanitation guidance
- Follow-up or maintenance recommendations
