How to identify flies
- Size
- House flies 6–7mm; blow flies 10–14mm
- Colour
- Grey with dark stripes; blow flies metallic blue or green
- Active
- Peak activity summer months, some species year-round
- Four dark stripes on the thorax of a house fly
- Clusters at windows and around light fittings
- Small dark specks on surfaces and light shades
- Maggots indicate a breeding source within a few metres
Commonly confused with: Cluster flies and house flies are often reported interchangeably. Cluster flies arrive in autumn in large numbers and are sluggish; house flies are active year-round.

What to do before we arrive
Do this
- Find and remove the breeding source — bins, drains, or something dead in a void
- Clean bin areas with a degreaser, not just water
- Check drains and gullies for organic build-up
- Keep a note of which room they cluster in
Avoid this
- Do not just spray adults; the source will keep producing more
- Do not ignore a sudden indoor swarm — it usually means a dead animal in a void
- Do not leave standing water in trays or drip pans
- Do not rely on window fly-papers as a control method
