Fly Control in London
Professional fly pest control for London homes, flats, restaurants, commercial kitchens, cafés, pubs, hotels, offices, bin stores and managed buildings. We identify the fly species, find the breeding source and provide targeted treatment and prevention advice.
Quick answer: professional fly control in London
Bon Accord Pest Control provides professional fly control in London for domestic and commercial properties. A proper fly treatment is not just spraying the room. The most important step is to identify which type of fly is present and then find where they are breeding, entering or being attracted from.
House flies, bluebottles, fruit flies, drain flies and cluster flies all need different control methods. A treatment that works for cluster flies in a loft will not solve drain flies emerging from organic build-up inside a floor gully. A quick knockdown of adult flies may give short relief, but the problem will return if the source remains.
Why flies are more than a nuisance
Flies can be annoying in a home, but in a food business they can become a hygiene, audit and reputation issue. Flies may land on waste, drains, refuse, faecal material, dead animals and decaying food before landing on worktops, food-contact surfaces or uncovered food.
In restaurants, hotels, cafés, bars and commercial kitchens, visible flies can lead to customer complaints, poor reviews, internal audit failures and pressure from environmental health. In domestic homes and flats, a sudden or repeated fly problem can point to hidden waste, a dead animal, drainage issues, a communal bin problem or seasonal cluster fly activity.
The most important step: identify the fly first
Different flies point to different causes. Identification affects the inspection route, the treatment method and the prevention advice. Small flies around a bar may be fruit flies from fermenting liquid. Small moth-like flies around a floor drain may be drain flies breeding in organic slime. Slow flies at upstairs windows may be cluster flies resting in a roof void.
| Fly type | What it may indicate | Typical control focus |
|---|---|---|
| House flies | Food waste, bins, organic matter, open doors or windows | Hygiene, waste control, entry reduction and adult-fly treatment where suitable |
| Bluebottles / blow flies | Rotting food, bins, a dead rodent, dead bird or other carcass source | Find and remove the source, clean affected areas and treat adult flies |
| Fruit flies / vinegar flies | Overripe fruit, beer, wine, syrup residue, bar waste and sticky recycling | Remove fermenting source, deep clean residues, trap and prevent recurrence |
| Drain flies / moth flies | Organic slime in drains, floor gullies, pipework, damp areas or wet basements | Clean breeding material, improve drain hygiene and control adult flies as support |
| Cluster flies | Seasonal entry into lofts, upper rooms and roof spaces to rest or hibernate | Vacuum removal, treatment of resting areas and proofing advice |
| Lesser houseflies | Often circling lights or moving through kitchens, waste rooms and indoor spaces | Find the breeding source, improve sanitation and use targeted control |
Our London fly control process
Fly control works best when it follows a structured process. Bon Accord Pest Control uses an inspection-led approach, because the visible adult flies are often only the symptom. The real problem may be behind a kitchen unit, inside a drain, in a refuse room, in a loft void or outside the building.
Inspection and identification
We identify the fly type and inspect the areas where activity is strongest, including kitchens, bins, drains, windows, lofts, refuse rooms and food preparation areas.
Source finding
We look for breeding material, dead animals, drain biofilm, food waste, bin residue, moisture, damaged pipework, open entry routes and poor waste handling.
Immediate reduction
Where appropriate, we reduce adult fly numbers using professional methods suitable for the setting and risk level.
Source treatment
The long-term result comes from removing or controlling the cause, not only knocking down adult flies.
Prevention advice
We advise on cleaning, waste, proofing, fly screens, UV units, drain hygiene and monitoring.
Monitoring and records
Commercial sites may need visit notes, action points and ongoing checks to support food-safety compliance.
Fly control for homes and flats in London
Flies in homes and flats can be caused by open windows, warm weather, bins or food waste, but repeated or heavy fly activity needs proper investigation. In London flats, the source may not always be inside the individual property. It may come from communal bins, a refuse room, rubbish chute, drains, neighbouring properties, dead rodents in voids or shared service areas.
You should arrange professional advice if flies appear every day despite cleaning, bluebottles suddenly appear indoors, maggots are found near bins or under units, small flies gather around sinks or drains, or dead flies collect near upstairs windows.
Commercial fly control in London
Commercial fly control must be discreet, practical and recordable. A restaurant, hotel or food business does not only need flies killed; it needs the cause identified and a prevention plan that works around daily operations.
Bon Accord can support restaurants, cafés, pubs, bars, hotels, bakeries, offices, schools, food retailers, commercial kitchens, dark kitchens, warehouses, property managers, serviced apartments and residential blocks with bin stores or refuse rooms.
| Commercial site | Common fly risks | What we check |
|---|---|---|
| Restaurants and cafés | Food waste, floor drains, open doors, dirty under-counter areas | Drains, bins, food-prep areas, pot wash, rear yards and UV unit placement |
| Bars and pubs | Beer residue, syrup, bottle bins, drip trays and drains | Bar waste, bottle storage, sticky residues, sinks, gullies and refuse routines |
| Hotels and serviced apartments | Guest rooms, housekeeping waste, food service, laundry and refuse rooms | Bedrooms, windows, waste areas, kitchens, staff areas and loading points |
| Blocks of flats | Bin stores, refuse rooms, chutes, communal doors and food waste | External bins, internal refuse rooms, door gaps, drains and cleaning routines |
| Food production and storage | Open product, waste, goods-in doors and poor exclusion | Doors, screens, stock control, proofing, monitoring and pest records |
Fly control for restaurants, cafés and commercial kitchens
Restaurants and commercial kitchens are high risk because flies are attracted to warmth, moisture, food residue, bins and waste handling areas. A few flies in a customer-facing area can quickly become a complaint, but the source is often in a back-of-house location.
Common problem areas include pot wash areas, floor drains, under sinks, under counters, beer drip trays, bottle bins, food waste bins, recycling, rear yards, bin stores, grease traps, dishwasher areas, mop buckets, delivery entrances and open kitchen doors.
Drain fly control in London
Drain flies, also called moth flies, are small fuzzy flies often seen around sinks, floor gullies, showers, toilets, plant rooms, damp basements and commercial kitchen drains. They are common in restaurants, bars, basements, bathrooms and areas with poorly used or dirty drains.
The key with drain flies is source removal. The larvae develop in organic material inside drains, traps and wet pipework. Spraying the adult flies alone usually fails because more flies continue to emerge from the drain source.
| Drain fly sign | What it suggests | Best next step |
|---|---|---|
| Small fuzzy flies near sinks or gullies | Possible organic build-up inside the drain or trap | Inspect and clean the drain source |
| Activity on tiles or walls near wet areas | Moisture and breeding material nearby | Check leaks, wet floors and pipework |
| Repeated flies after surface cleaning | Breeding source remains below the surface | Deep drain/gully cleaning may be needed |
| Basement or plant-room activity | Standing water, poor drainage or damp organic matter | Check drainage, moisture and hidden build-up |
Fruit fly and vinegar fly control
Small flies around fruit bowls, bars, bottle bins, syrup spills, beer residue and sticky surfaces are often fruit flies or vinegar flies. They are especially common in bars, restaurants, cafés, staff kitchens and domestic kitchens with fruit waste.
The control plan is simple in principle but detailed in practice: remove the fermenting source, clean sticky residues, manage bins, inspect drains and treat adult flies where appropriate. If the sticky residue under a bar, behind a bottle bin or inside a floor gully remains, the problem is likely to return.
Bluebottle and blow fly control
Bluebottles and blow flies are larger flies that may indicate decaying organic matter. A sudden appearance of many bluebottles indoors can sometimes point to a hidden source such as rotting waste, a dead rodent, a dead bird or contaminated refuse.
The correct treatment is not just to spray visible flies. The source should be found and removed if possible, affected areas should be cleaned, and adult flies should then be controlled. If the source is inside a wall void, chimney, loft, cellar or external bin area, the inspection needs to be methodical.
Cluster fly control in London
Cluster flies are different from house flies and drain flies. They often appear in upper rooms, lofts, roof spaces and around windows, especially in autumn and spring. They may return to the same building year after year.
Signs include slow-moving flies at upstairs windows, large numbers in lofts or roof spaces, dead flies on window sills, recurring seasonal activity and flies appearing on warm winter or spring days. Treatment may involve vacuum removal, targeted treatment of resting areas, loft or roof-space treatment where suitable and proofing advice.
Fly control in bin stores and refuse rooms
Bin stores are one of the most common sources of fly activity in London. This is especially true in blocks of flats, restaurants, mixed-use buildings, hotels and offices. Waste areas often provide the warmth, moisture and organic material flies need.
We check bin lids, spilled waste, bin liquids, floor drains, cleaning frequency, collection schedule, access doors, ventilation, gaps around doors, fly activity on walls and ceilings, maggots near bins and staff waste-handling practices.
What to do before we arrive
For homes, take photos of the flies if possible, note where activity is strongest, check bins and food waste, look at drains and sinks, keep windows closed if flies are entering and avoid using multiple DIY sprays before inspection.
For commercial premises, keep samples or photos if possible, record where staff see activity, check bin areas and drains, keep pest records available, note any recent drain or building work, protect food and food-contact surfaces and avoid spraying near food.
| Do | Avoid |
|---|---|
| Take clear photos and note where flies are strongest | Do not clean away all evidence before taking photos |
| Check bins, drains, waste areas and wet zones | Do not pour insecticide down drains |
| Keep food covered and surfaces protected | Do not spray supermarket products near food preparation areas |
| Tell us about recent drainage, waste or building work | Do not move UV units or traps without advice |
| Keep commercial pest records available | Do not rely on one-off adult fly knockdown if the source remains |
What not to do
- Do not rely only on supermarket fly spray for repeated infestations.
- Do not spray insecticide near food preparation areas or uncovered food.
- Do not pour insecticide down drains.
- Do not place UV fly killers above food preparation surfaces.
- Do not ignore maggots, drain flies or repeated bluebottles.
- Do not assume all small flies are fruit flies.
- Do not assume all large flies are simply coming from outside.
- Do not keep food waste bins beside open doors where possible.
- Do not leave sticky drink residue under bars or bottle bins.
- Do not treat drain flies without cleaning the drain source.

Fly control FAQs
Do you provide fly control in London?
Yes. Bon Accord Pest Control provides fly control across London for homes, flats, restaurants, hotels, cafés, pubs, commercial kitchens, offices, bin stores and managed buildings.
How do you get rid of flies properly?
The correct method depends on the fly species. We identify the fly, find the source, reduce or remove breeding material, treat adult flies where appropriate and recommend prevention steps.
Why do flies keep coming back after spraying?
Spraying may kill adult flies, but if eggs, larvae or breeding material remain, new flies continue to emerge. The source must be found and dealt with.
Are flies a food hygiene risk?
Yes. Flies can contaminate food, surfaces and equipment. They are especially important in restaurants, cafés, bars, hotels and commercial kitchens.
What are the signs of a fly infestation?
Signs include live flies, dead flies, buzzing, maggots, fly spots, flies around bins or drains and repeated activity in the same area.
Can flies come from drains?
Yes. Drain flies breed in organic build-up inside drains, traps and wet areas. Cleaning the breeding source is more important than simply spraying adult flies.
Do you treat drain flies?
Yes. We can inspect suspected drain fly activity, identify likely sources and advise on the correct drain cleaning, hygiene and treatment plan.
Are fruit flies the same as drain flies?
No. Fruit flies are usually linked to fermenting fruit, alcohol, sticky residues and food waste. Drain flies are usually linked to organic slime in drains, gullies and wet pipework.
Why are there bluebottles in my home?
Bluebottles may enter from outside, but a sudden indoor outbreak can sometimes indicate a hidden source such as rotting waste, a dead rodent or a dead bird in a void.
What are cluster flies?
Cluster flies are sluggish flies that often gather in lofts, roof spaces and upper rooms to rest or hibernate. They can return to the same building year after year.
Can a restaurant stay open with flies?
That depends on the severity and hygiene risk. Food businesses must control pests and protect food from contamination. If flies are present, urgent action and records are important.
Where should UV fly killers be placed?
UV fly killers should be positioned carefully and should not be placed above food preparation surfaces where insects may fall onto food or equipment.
Do UV fly killer tubes need replacing?
Yes. UV tubes lose attraction power over time even when they still appear bright to people. Tubes should be changed according to the manufacturer’s instructions.
Can I treat flies myself?
Small numbers may be reduced with cleaning, traps and entry prevention. Repeated, heavy or commercial fly problems should be professionally inspected because the breeding source may be hidden.

Where Do Flies Come From And How To Control Them?
Bin areas is one of most common places where you can find flies. The term ‘fly’ actually encompasses a range of different insects, each of which has its own habitat and needs to be dealt with differently. However, the most common flies that most people encounter are the common house flies. Decaying organic matter, including fruit, food, and trash, can all attract nearby flies. They love to sniff out compost piles and rubbish bins. Bins around residences and businesses are all susceptible to interest from flies.
The other thing flies love is sugar. Accordingly, if you have fruit trees on your property, fallen fruit will often draw out flies looking for a sugary snack. If you spill any sugary or alcoholic drinks in your property, these can also attract flies if you don’t clean them away quickly. Where there are overripe fruit and sugary residue, flies will breed.
There are some flies, known as drain flies or filth flies, that seek out moist areas to lay their eggs. They take their names from the fact that they often choose drains and sewers to lay their eggs and make nests.

What Are The Most Common Signs Of A Fly Infestation?
Like other pests, the most immediate sign that you have an infestation of flies in the presence of the insects themselves. However, it is worth noting that a swarm of flies does not automatically indicate an infestation. If there is a fly nest near to your property, swarms of flies may well head over your way in search of food and sugar. In fly nests, dozens of eggs can hatch at almost exactly the same time. When this happens, the swarm of siblings will often fly away together.
If your neighbours have a flies’ nest in their home or garden, or if you live near to an allotment or food business, flies that hatch next to your property can find their way to you. No one wants to see swarms of flies in their home or business, but they don’t necessarily indicate a serious problem. Of course, the only way to be sure is to call in an expert pest control technician to make an assessment for you.
Not everyone realises that the larval stage of a fly is a maggot; many people think these are two separate organisms. But the presence of maggots indicates the presence of flies in the same way that you can’t have wild kittens without a mother rabbit or cat. People often think that maggots are formed in the decaying flesh of other organisms. In fact, you find maggots around dead things because flies lay their eggs in and around decaying matter.
You might begin to notice small dark clusters of spots on the lighter parts of your property. These clusters are small, only around the size of a pinhead or so.
What Can You Do To Prevent Fly Infestation?
Flies might seem harmless enough, but they can cause several serious issues for homes and businesses. Given how common flies are (you will find them even in the cleanest and hygienic places. It is important to be clear about what risks they can present to you and your property.
You can’t put a price on your health or that of your family. If you allow a fly infestation to fester and grow unabated, it puts you and those around you at risk. For businesses, the presence of a fly infestation threatens the health of your customers and the reputation of your business. No one wants to shop with a business that is infested with flies and rife with maggots. Businesses in the food services and hospitality sectors are even more vulnerable to the negative publicity that comes from being associated with a pest infestation.
Fruit flies can also cause some unique problems of their own. Tiny fruit flies, known as bar flies, thrive on substances high in fructose. Such substances include fruit juices, alcoholic and fizzy drinks, fruity liquors, overripe fruit, and food residue in sinks and drains. Female fruit flies lay their eggs within ripening fruit or fermenting liquid. The larvae feed on the food or liquid once they hatch. If you ingest a fruit fly larvae, it can cause gastrointestinal discomfort and diarrhoea. Fruit flies can also cause cross-contamination of food and drink by transferring bacteria and pathogens they come into contact with elsewhere.
Flies are often associated with dirt, death, and disease. In rural areas, they are a common sight on and around decaying animal carcasses. The reputation they have is a well-deserved one. Because flies are attracted to decaying organic matter, including food and animals, and even lay their eggs in these environments, they regularly come into contact with bacteria and other pathogens that are extremely harmful to humans. For example, flies can transmit E. Coli and salmonella from the meat and faeces they come into contact with.
How To Prevent Fly Infestations - Pest Management
There are numerous things you can do to reduce the number of flies around your property and discourage them from forming nests. For example, many flies will make their way into your home at night through an open window.
This is particularly common in the summer months when many people sleep with windows open. Like other insects, they are attracted to the artificial light in your home after the sun goes down. Keeping your windows closed will deny them entry to your home, to begin with. If you need to have your window open, fly screens will enable air to freely flow while preventing flies and other insects from invading your property.
Another simple thing you can do to discourage flies from visiting your home is to make sure you cover any food and food debris in your kitchen. This covers food that you throw away in outdoor bins. Try to ensure that bin bags are properly tied and sealed so flies can’t access the food within.

How do I get rid of flies in my loft?
A large gathering of flies in your loft space, attic or wall voids particularly in autumn is likely to be cluster flies. Cluster flies are large and black, just like house flies. They can easily be mistaken for them so if you seal cracks or crevices around windows in your home this will help stop the cluster fly from entering. If they already have entered though it might take more than DIY direct contact sprays because these pests need an expert pest controller to get rid of them completely!
Are fruit flies harmful?
The fruit fly larvae have the potential to cross contaminate food and drink with bacteria. They can cause discomfort, diarrhoea as well as being attracted by high-fructose substances such over ripe fruits or sweet fruity liqueur like Cointreau or Vermouth which will make it easier for these bugs to get inside your body!
It’s important not only be mindful of what type of mess you are making but also where those pesky flies might come from; they love hanging out near ripening avocado pits at restaurants because their natural sugar content makes them an attractive source for this pest — just one example among many other places across all industries that may host similar risk factors including sinks in bars kitchens.
Flies and fly control FAQs
Common house flies can fly into a property from close by where they have been breeding in decaying organic matter (such as meat, fruit, vegetables) or faeces. These include compost piles, farms, road kill, rubbish bins – in fact anywhere there is decaying organic matter, including organic residue in your own bins. Fruit flies like sugary substances and feed and breed on overripe fruit, spilled soft drinks and alcohol residue. Drain or filth flies, as the name suggests seek moist areas to lay their eggs such as drains.
The flies can transmit disease and pathogens like Salmonella. They don’t frequent the cleanest environments, breeding in decomposing matter or faeces which attracts more bacteria to stick on their bodies as they crawl around picking up anything for a meal from food surface somewhere else cleansed less than ideal locations such places could make you sick too
- A) Flies carry harmful germs
- B )Flies visit dirty spots
- C)Bacteria is transferred onto Fly
- D), The fly then deposits its contents elsewhere
If an alarming number of flies are swarming around your property, it could mean that they’re hatched and developed into adults in gardens or on the premise. They may have bred from fresh manure-rotting food stuffs like garbage and decaying organic materials such as old compost heaps which can all provide them with a place to lay their eggs before feasting themselves upon these newly laid larvae.
