Flies

There are a staggering 120,000 species of flies globally. Flies are often unwelcome due to the health risks they pose to people, pets, and livestock. They are carriers of food poisoning, dysentery, and diarrhoea contaminating homes and businesses with diseases like Salmonella and E.coli. Some fly species can even bite, like the Horse Fly. Combatting fly infestations requires a tailored approach, ranging from common fly sprays to advanced solutions like Rentokil external EcoCatch Fly Traps and our Lumnia LED fly Killers.

For businesses understanding the seasonal impact of fly populations is crucial, and we work alongside you to design a comprehensive fly control programme to exclude, restrict, destroy and monitor fly infesations. Our team of pest control technicians are trained to identify the species and understand your unique business needs, challenges and environment to provide the best fly control solutions for you.

How to Stop Flies

Stopping flies getting into your property is never easy. If a small fly problem is left uncontrolled, it has the potential to turn into a serious fly infestation. Some fly species can mature from eggs to adults in just seven days. There are simple ways you can identify the signs of a fly infestation and reduce the need for fly control. For businesses, taking a proactive approach to get rid of flies will also help you avoid more costly treatments to eliminate flies if an infestation becomes more serious.

In the UK we have several types of fly that can be a nuisance, the common house fly is a carrier of food poisoning and diarrhoea, the cluster fly, the horse fly which has a painful bite, the fruit fly (or lesser fruit fly) that can transmit bacteria via the fruit they infect and bluebottle (or blow fly) that can spread bacteria, as they feed on faeces and rotting food, are a few. Here are some helpful facts about different types of flies their larvae, lifecycles and how you can identify them.

Flies and fly control FAQs


  • Where do flies come from?

    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.


  • Are flies dirty?

    Yes, flies can carry and transmit pathogens and diseases like Salmonella and E. coli. They don’t frequent the cleanest environments, breeding in decaying matter and faeces. Whatever surfaces flies visit and crawl on, bacteria can stick to their bodies, especially their legs and wings, to then be deposited on food and clean surfaces elsewhere.


  • What does a swarm of flies in your house mean?

    Swarming flies in your property means dozens of fly eggs have recently hatched and developed into adult flies close by in gardens, allotments or your own garage or attic. They could have bred in fresh manure, rotting food stuffs, rubbish, and decaying organic materials and are now looking to feed so they in turn can breed.


  • 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. Common cluster flies (Polleniarudis) are large and black and look very similar to house flies so can easily be mistaken for them. If you seal cracks and crevices around windows, under eaves, fascia’s and door frames this can help to prevent them entering. Once cluster flies are inside you can use DIY direct contact sprays on visible adults, but for those flies already hidden and hibernating you will need the expertise of a professional pest controller to eliminate them completely.


  • Are fruit flies harmful?

    If you inadvertently consume the fruit fly larvae they can cause discomfort and diarrhoea.Tiny fruit flies, also known as bar flies thrive on high-fructose substances like over-ripe fruit, juices and alcohol residues - sweet fruity liquors such as Cointreau or Vermouth. They are also attracted to food residue in sinks and drains. They have the potential to cross contaminate food and drink with bacteria and pathogens. Female fruit flies lay eggs in ripening fruit and sweet fermenting liquids (open liquor and syrup bottles for example). Once hatched the larvae feed directly on the over ripened food or sugary liquids.
