How to keep flies away

Flies can be a nuisance pest for businesses. A fly infestation could pose a serious health risk as flies are known to spread a range of diseases, like Salmonella and E.coli. 

If you want to prevent flies, there are some practical steps you can take to deter them. Some of these methods are totally cost-free and only require your time to action. 

Recommended steps involve making changes indoors and outdoors to cover all potential hot spots and ensure effective fly control.

Fly prevention tips

  • Deny flies access - keep windows and doors closed.

  • Flyscreens - fit flyscreens to windows especially around kitchen and waste areas.

  • Cover food - flies spread diseases by landing on food before we eat it.

  • Clear away - clear food debris and liquid spillages from food consumption and preparation areas, under kitchen benches and appliances.

  • Dustbins / Compost bins - ensure all waste containers have tightly sealed lids.

  • Pets - clean up after pets. Not only are faeces a perfect breeding place for flies, they may land there before landing on your food.

  • Clear up dead flies - they provide a tasty snack for other pests such as carpet beetles.

  • Standing water - do not leave standing water (in watering cans and pot plants for example) as this offers mosquitoes opportunity to breed.

  • Ponds - if you have a garden pond, introduce goldfish as they will eat mosquito larvae.

  • Drains - ensure drains are kept clean and free of debris to reduce fly breeding sites.

FACT: Common house flies are attracted to decaying organic waste such as faeces and rotting meat, whereas fruit flies will look for sugary substances and feed more commonly on overripe fruit, spilled soft drinks and alcohol.

Tips to get rid of flies

If you have a fly problem the first step is to take these easy practical measures to stop flies having access to food and liquids around your property. These steps will also help to prevent flies returning:

Keep food covered: any type of food, even crumbs, can attract flies and encourage them to lay eggs nearby. Leftovers should be carefully covered up. Their contact with your food is also main cause of food contamination

Deny access to water: fix leaky taps and blocked drains where water can gather. Flies need moisture to survive

Practice good food hygiene: keep your food areas, garbage containers, sinks and drains clean and dispose of garbage regularly to prevent it attracting flies or becoming a fly breeding site. Liquid food sources for flies can accumulate in various places due to poor hygiene practices, such as:

  • Garbage containers
  • Over-ripe fruit, and some vegetables
  • Old drink bottles
  • Drains
  • Spills that are not cleaned properly
  • Cracks in floors

Cover entry points: fit fly screens to windows and keep windows and doors shut 

Install a fly killer unit: fly killers are essential for capturing flies in businesses handling food

Keep bird feeders clean: keep them clean and remove bird food before dusk 

Remove clutter: eliminate clutter in your business, home and garden; messy sites could provide breeding places for flies
