Need help with a Fly problem?
Commercial fly issues
Commercial fly problems are common in restaurants, bars, cafés, food shops, offices and other premises where food, drink, waste or drains can support fly activity.
Every site is different, so the treatment plan depends on the fly species, breeding source, hygiene conditions, waste handling, drainage and layout of the premises.
In many commercial settings, effective fly control may require a combination of source removal, cleaning advice, treatment, monitoring and ongoing prevention.
For businesses that need regular inspections and reporting, our commercial pest control contracts can include fly monitoring alongside wider pest management.
Offices, retail units and shared commercial spaces can also experience fly problems, especially where food is stored at desks, waste remains in bins, or spills and organic residues build up in kitchens, staff rooms or storage areas.
The first step is usually to identify and remove the source. This may involve improving waste handling, cleaning affected areas, checking drains and removing food residues that support fly activity.
Where treatment is required, we may use residual spray, ULV fogging or other suitable methods depending on the fly species, room layout and source of the infestation.
How does the fly treatment work?
Fly treatment starts with identifying the species and the likely source of the activity. This is important because fruit flies, house flies, bluebottles and drain flies often need different treatment and prevention steps.
Where appropriate, we may apply residual insecticide to selected surfaces where flies are likely to rest. This can help reduce active fly numbers while the source of the infestation is addressed.
In some situations, we may also use ULV fogging to help knock down active flies in the treated space. Before fogging, food must be removed or sealed, and exposed food-contact surfaces, utensils and kitchenware should be cleaned before use after the treatment.
How much does fly control cost in London?
Our fly control service starts from £178 + VAT for homes, flats and commercial premises in London.
The final treatment plan depends on the fly species, the source of the infestation, the size of the affected area and whether cleaning, drain work, exclusion or ongoing monitoring is required.
For more detail on how treatment prices are calculated, read our pest control cost guide.
We most commonly deal with fruit fly and drain fly problems. We also investigate bluebottle activity where a carcass or another decaying organic source may be involved.
Types of flies in London
Fruit fly problems can affect both homes and commercial premises. In homes, they are often linked to overripe fruit, vegetables starting to spoil, food residues, bins, drains or spillages in kitchens and utility areas.
In commercial premises such as bars, pubs, restaurants, cafés and ice cream parlours, fruit flies are often linked to sugary residues, beer lines, drinks spillages, fresh fruit, drains, bin areas and poor access for cleaning.

Long-term control depends on finding and removing the source. This may involve improving stock rotation, emptying bins more often, cleaning drains and surfaces, drying wet areas and storing products in sealed containers.
Where cleaning and source removal are not enough, treatment and monitoring may be required to bring activity under control.
House flies can be a concern in food-handling environments because they may contaminate food, food-contact surfaces and preparation areas.
Adult flies are attracted to food, waste and breeding material, so treatment should focus on both active flies and the source supporting them.
Depending on the site, control may involve fly screens, electronic fly killers, improved waste management, cleaning recommendations and targeted treatment where appropriate.
Bluebottle fly activity can appear suddenly inside a property, sometimes with large numbers of flies appearing in one room or around windows.
The source is often a dead rodent, pigeon or other animal hidden under floorboards, in a chimney, roof void, shaft, wall void or other inaccessible area.
Treatment can help reduce active flies and make the affected area usable again, but the best long-term outcome usually depends on identifying and removing the source where access allows.
Drain flies, also known as filter flies, are often linked to standing water, organic build-up, grease, damaged pipework, back surges or poorly maintained drains.
They are usually seen around sinks, floor drains, bathrooms, basements, commercial kitchens or areas with persistent moisture.
Control depends on removing the breeding source. This may involve cleaning, drain maintenance, enzyme or drain cleaner use, repairs, or drain jetting where needed.
