How to Reduce Flies in the House

Work out what is attracting flies, improve hygiene and screening, and distinguish occasional visitors from a breeding source that needs attention.

Key points & steps

Identify where flies are concentrated: kitchens, bins, drains, pet areas and windows can suggest different sources.
Remove food waste promptly, clean spills and bin lids, and keep food covered or refrigerated where appropriate.
Rinse recycling and avoid leaving wet organic waste standing indoors for long periods.
Use fly screens, door curtains or well-fitting window screens where doors/windows are regularly left open.
Clean drains and waste areas appropriately if small flies are repeatedly appearing around sinks or utility areas.
Use simple traps or fly papers where appropriate; if using a household insecticide, use only a product intended for that pest and follow the label.
Investigate persistent large numbers because a hidden food source, dead animal, drain issue or other breeding site may be present.

A single open window can explain occasional flies; repeated emergence from one room usually deserves more investigation.
Do not spray insecticide over food, utensils or food-preparation surfaces.
Keep pet feeding and litter areas clean because they can provide both food and moisture for flies.
