Flies are rarely breeding where you can see them. Catch them at the source with Birmingham Pest Control Co.
A blow fly circling indoors in winter has come from something dead in a wall void or floor cavity, and clearing the adults without removing the breeding source means the next generation hatches regardless.
Cluster flies gathering at upstairs windows in September hatched in garden soil over summer before moving inside to overwinter.
Drain flies in a bathroom breed inside the waste pipe, not on the surfaces near the sink where they become visible.
Birmingham Pest Control Co. provides flying insect and fly pest control for homes and businesses across Birmingham and the West Midlands.
Our BPCA-accredited pest control technicians identify the fly species, locate the breeding source, and carry out a treatment programme matched to what’s actually causing the problem.

Flying insects we treat in Birmingham
Most fly callouts across Birmingham and the surrounding areas come from a small group of species, and each one breeds somewhere different.
House flies settle around food waste and kitchen areas, blow flies trace back to a dead animal in a wall void, and cluster flies arrive from garden soil as temperatures drop in late summer and autumn.
The treatment for each type of pest differs significantly, which is why identification comes before any treatment begins.
Birmingham Pest Control Co. targets the source of the infestation and once it is cleared we empower you with the knowledge to prevent it from returning.
House flies and blow flies
House flies
House flies (Musca domestica) and the lesser house fly breed on food waste, animal faeces, and decaying organic matter before moving onto food preparation surfaces and open food.
Because they travel from waste to worktop in the same foraging cycle, house flies transmit diseases such as Salmonella and E. coli.
That makes them a genuine public health risk in any premises handling food, not simply a summer nuisance.
Persistent house fly activity in Birmingham kitchens and food businesses most often traces back to a bin without a tight-fitting lid, a floor drain accumulating organic residue, or food waste near a service entrance.
Addressing the breeding source alongside treating the visible adults is what prevents the population cycling back within days of treatment.
Blow flies (bluebottles and greenbottles)
Blow flies are the larger metallic flies: the bluebottle (Calliphora vomitoria) and the greenbottle (Lucilia sericata).
They lay eggs on carrion, and a cluster of blow flies appearing indoors, particularly in winter when windows are closed, almost always points to a dead animal in a wall void, a loft, or beneath a suspended floor.
Birds, rats, and mice that die inside buildings provide the breeding source, and the maggot stage develops and completes well before detection becomes straightforward.
Finding and removing the dead animal is part of the job.
Treating the adult blow flies without clearing the carcass leaves the infestation source in place, and fly activity continues until the breeding material is gone. Our pest control technicians check the most likely locations based on where blow fly activity is heaviest.
A rodent and bird control survey can be carried out at the same time if there are signs of wider pest activity in the building.
Cluster flies in Birmingham lofts
Cluster flies (Pollenia rudis) live and breed outdoors through spring and summer, with larvae developing as parasites inside earthworms in garden soil and open ground.
As temperatures drop in late summer and autumn, they move indoors to overwinter in large numbers and return to the same property year after year.
Loft spaces and roof voids in Birmingham’s Victorian and Edwardian terraced housing are a particularly common harbourage, because the roof structure provides the sheltered, unheated space cluster flies prefer.
On warm autumn days, cluster flies leave the roof void and gather at upstairs windows and light fittings in numbers that can make a room difficult to use.
A cluster fly looks different from a house fly: slightly larger, darker, with distinctive golden-yellow hairs on the thorax, and the wings overlap flat when resting. The group behaviour at windows and the sheer volume involved are usually enough to identify them without further inspection.
Treatment for cluster flies addresses the loft space rather than the individual flies at the window.
We treat the roof void and fit proofing measures to the entry points cluster flies use to enter.
A one-off treatment without proofing leaves the same harbourage open for the next year’s population.
Fruit flies and drain flies in kitchens and bathrooms
Fruit flies
Fruit flies (Drosophila melanogaster) are the small flies with red eyes that appear around fruit bowls, recycling bins, bar drip trays, and anywhere fermented or rotting organic matter has accumulated.
They breed fastest in warm kitchens and hospitality settings, where a piece of overripe fruit or an undrained drip tray provides enough material for several generations within a week.
Clearing fruit flies means finding and removing the breeding source, not just reducing the adults you can see.
An overlooked bin, fruit left at the back of a bowl, or a bar counter drip tray that isn’t cleaned out regularly will sustain a fruit fly population through multiple treatment rounds if the source remains.
Once the breeding material is removed, insecticidal treatment brings fly numbers down quickly.
Drain flies
Drain flies (Psychodidae) are small, fuzzy, moth-like flies that breed in the biofilm inside waste pipes, overflows, and floor drains.
The bathroom drain is the most common breeding site in residential properties, which is why drain flies appear in bathrooms rather than kitchens even where there’s no obvious food source.
In commercial properties with multiple drain connections, the source is sometimes a rarely used floor drain or a storm drain near a kitchen entrance.
Clearing the biofilm inside the pipe stops larvae from completing development, and fly numbers drop once the source is gone.
A drain brush and enzymatic drain cleaner disrupts the biofilm effectively.
If drain fly activity continues after cleaning, the source may be a cracked drain section where organic matter accumulates between pipe joints rather than running clear. Our pest technicians identify which drain is feeding the problem so it doesn’t return once pest removal is complete.
Horse flies and other biting flies
Horse flies (Tabanidae) are large biting flies that emerge in late summer, with females feeding on blood.
They appear near water and livestock, and while Birmingham city centre is less affected than the rural edges of the West Midlands, properties near the canal network, open farmland to the south and east of the city, or stabling near suburban areas do see horse fly activity through July and August.
We treat horse flies where they’re causing problems for people or animals.
How we treat flying insect problems in Birmingham
Flying insect control is an integrated process: survey first to identify the species and locate the breeding source, then treatment matched to that species, then proofing to reduce the likelihood of recurrence.
No single product or method addresses every fly type, and applying a contact insecticide without removing the breeding source produces a temporary reduction in fly numbers rather than effective pest control that lasts.
House and blow fly treatment
For house flies and blow flies, we identify and remove the breeding source as part of the treatment.
In commercial kitchens and food businesses, we install electric fly killers and LED fly control units, which capture target insects on a board without spraying product over food.
LED fly control units attract flies more consistently than traditional UV systems, require less frequent maintenance, and are the standard installation for food businesses dealing with ongoing fly pressure across Birmingham and the West Midlands.
Cluster fly treatment
Cluster fly treatment addresses the loft space and seals the gaps the flies use to enter.
Fruit and drain fly treatment
Fruit flies and drain flies require the breeding material to be removed or disrupted as part of the treatment, because fly populations rebuild from the source if it’s left in place.
For larger infestations, fogging of an enclosed space brings fly numbers down quickly before proofing control measures are installed.
Proofing and prevention
Proofing closes the routes flying insects use to access and breed inside a property.
Gaps around pipe entries, cracked drain sections, open loft access hatches, and poorly fitted soffit boards all provide access points, and each one left unsealed leaves the same fly infestation available to reestablish.
Our pest technicians identify and seal these during every residential fly control job.
Between pest control visits, practical steps for homeowners and businesses include storing food in airtight containers, keeping bin lids fitted and bins emptied regularly, cleaning drip trays and bar areas thoroughly, and checking for slow-draining sinks or floor drains where biofilm builds up.
Regular cleaning under and behind kitchen appliances removes the decaying organic matter and food sources that sustain house fly breeding sites.
Flying insect pest control for Birmingham businesses
Commercial properties in Birmingham face persistent fly pressure because the kitchens, food waste, and drainage that keep the city’s food and hospitality sector running also sustain house flies and drain flies year-round.
Restaurants and bars along the Broad Street corridor, food businesses in Digbeth, catering operations in the Jewellery Quarter, and university refectories deal with fly activity as an ongoing operational issue rather than an occasional nuisance.
House flies transmit pathogens that contaminate food preparation surfaces.
Under the Food Safety Act 1990, food businesses are required to maintain adequate pest control arrangements, and Birmingham City Council’s Environmental Health team enforces this requirement.
Health and safety records need to reflect that pest issues are being managed actively rather than ignored until an inspection.
Our commercial fly control service in Birmingham covers installation of LED fly control units, scheduled servicing, and written records of every inspection and treatment.
Services for homes and businesses across Birmingham are available on a one-off or contracted basis, with scheduled visits providing the documented pest activity log that food safety audits require.
