Professional Fly Control in Kent
Flies in a Kent property are treated by GEM Services with a 4-stage process: source identification, source removal, knock-down treatment, prevention measures. Once the breeding source is eliminated, fly numbers drop rapidly within days. Treatment is carried out by a technician from a BPCA member company and quoted before anyone visits, and callouts peak in summer.
What you are dealing with: flies
Species we most often treat in Kent: Musca domestica (house fly) / Calliphora vomitoria (bluebottle)
House flies are short-lived but lay a great many eggs in that time. Eggs hatch into maggots very quickly and develop into adults within days in warm conditions. Bluebottles are larger metallic flies that breed in decomposing organic matter and meat.
Flies are attracted to food, waste, and decomposing matter. They taste with their feet, landing on surfaces to sample food. They vomit digestive fluids onto food before feeding, which is how they spread bacteria. House flies stay close to food sources and breed in warm, moist organic matter.
Flies feed on any organic material: food waste, animal droppings, decomposing matter, and sugary liquids. They breed in rotting food, compost, animal waste, and drains. A warm, food-rich environment like a kitchen or food processing area can support rapid population growth.
Where we usually find flies on a property
- ✓Wheelie bins and food waste containers
- ✓Drains with trapped organic matter
- ✓Compost heaps
- ✓Dead animals in wall cavities, chimneys, or under floors
- ✓Animal housing and stables
- ✓Commercial kitchen waste areas

Signs you have flies
Catching the problem early decides how much of it there is to treat. These are what we look for on arrival, and what is worth checking before you call.
Large numbers of flies indoors
A few flies are normal in summer. Persistently large numbers, especially concentrated in one room, suggest a breeding source nearby: rotting food, a dead animal, or a drain issue.
Maggots in bins or around food waste
White, legless larvae (maggots) in your bin, compost, or around pet bowls confirm flies are breeding on your property.
Clusters of flies at windows
Flies buzzing at windows are often trying to exit. If you find the same thing every morning, they may be breeding inside the building: in a wall cavity, loft space, or hidden waste.
Dark spots on walls and light fittings
Fly specks (regurgitated food and droppings) leave dark spots on walls, ceilings, and light fixtures. Heavy spotting indicates a sustained fly presence.
How we treat flies, step by step
Every job follows this sequence. What changes between properties is how long each stage takes, not the order.
- 1
Source identification
The priority is finding and eliminating the breeding source. We inspect bins, drains, loft spaces, and potential hidden sources like a dead animal in a wall cavity or under floorboards.
- 2
Source removal
We remove or address the breeding material. This might mean cleaning a fouled drain, removing a dead bird from a chimney, or advising on waste management improvements.
- 3
Knock-down treatment
For heavy infestations, we apply a targeted insecticidal spray to kill the existing fly population quickly. This provides immediate relief while the source removal takes effect.
- 4
Prevention measures
We install electric fly units (EFKs) for commercial premises and advise on proofing, drainage maintenance, and waste management to prevent recurrence.
How long it takesOnce the breeding source is eliminated, fly numbers drop rapidly within days. Commercial fly management is an ongoing service with regular unit maintenance.
What flies cost you if they are left
Flies in the kitchen contaminate food with bacteria from every surface they have landed on: bins, drains, and animal waste. A sudden increase in flies can indicate a hidden dead animal or drainage problem that needs attention.
Flies in a food business are an immediate Environmental Health concern. Food contamination, customer complaints, and potential closure are serious risks. Commercial kitchens, restaurants, and food production facilities require proactive fly management.
Health risks
- ⚠Salmonella, E. coli, and other bacterial contamination of food
- ⚠Dysentery and gastroenteritis from fly-borne pathogens
- ⚠Flies carry bacteria on their feet and spread it by vomiting digestive fluids onto food before feeding
Damage to the property
- ⚠No significant structural damage from flies
- ⚠Contamination of food stores and preparation areas
- ⚠Spotting on walls, ceilings, and fabrics from fly droppings
When fly problems peak in Kent
Fly populations peak from June to September when warm temperatures accelerate breeding. A single pair of house flies could theoretically produce millions of descendants in one summer if unchecked.
Keeping flies out after treatment
Treatment clears what is there now. These are what stop it coming back, and they are worth doing whether or not you use us.
- ✓Keep bins sealed with tight-fitting lids and clean them regularly in summer.
- ✓Clear up pet food bowls promptly. Do not leave food sitting out.
- ✓Fit fly screens to kitchen and dining area windows during summer months.
- ✓Check drains are flowing freely. Blocked or slow drains are a common breeding site.
- ✓Dispose of food waste frequently and do not let it accumulate indoors.
When you do not need us
A single fly sighting outdoors, away from the building and with none of the signs above, is usually not an infestation and does not need a treatment. Work through the prevention points first and see whether the activity continues.
Call us when the signs are repeating rather than one-off, when you find them indoors, or when you have tried proofing and the activity has continued.
We also do not carry out structural repairs. We seal and proof the entry points we find, but where the fabric of the building needs rebuilding, that is a builder’s job and we will say so.

Flies treatment: common questions
Why are there suddenly so many flies in my house?
A sudden fly invasion usually means there is a breeding source nearby. Common causes are a dead animal in a wall cavity or chimney, a blocked drain, or a bin that needs cleaning. We can identify and eliminate the source.
What is the difference between house flies and cluster flies?
House flies breed in food waste and are active in summer. Cluster flies are a different species that hibernate in buildings over winter. They enter loft spaces in autumn and emerge on warm days, sometimes in large numbers.
Do electric fly killers work?
Yes. Professional electric fly units are very effective in commercial kitchens and food areas. They attract and kill flies continuously without chemicals. We supply and maintain commercial-grade units.
Can flies breed in my drains?
Some fly species, particularly drain flies, breed in the organic film that builds up inside drains. Regular drain cleaning and maintenance prevents this. We can identify whether your drains are a breeding source.
Are fly sprays from the supermarket effective?
Aerosol fly sprays kill flies on contact but do nothing to address the breeding source. The flies will return unless you eliminate where they are breeding. Professional treatment combines knock-down with source elimination.
Book fly control in Kent
Flies problems do not resolve on their own, and the longer an infestation runs the more of the property it reaches. A treatment booked this week costs less and takes fewer visits than the same problem left until next month.
We prioritise fly callouts for food businesses. Residential visits are usually scheduled within a few days.
Once the breeding source is eliminated, fly numbers drop rapidly within days. Commercial fly management is an ongoing service with regular unit maintenance.
We cover the whole of Kent from our base in Ashford. Treatments are carried out by a technician from a BPCA member company, and we are fully insured.
