If you want to deter flies, there are some practical steps you can take. 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.

Tips to Keep Flies Away


Minimising Fly Infestation Tips

Deny flies access

Keep windows and doors closed.


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.


Ensure that build-up of grease is thoroughly cleaned every month.


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.

Water storage

Cover these with well fitted lids.

Standing water

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


If you have a garden pond, introduce goldfish as they will eat mosquito larvae.


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.
