Fly control Melbourne

Fly control treatment for a Melbourne home typically costs between $150 and $320 depending on the fly species and whether source extraction is required. A standard house fly or drain fly treatment starts from around $150. Blow fly treatments requiring roof void or subfloor inspection and carcass removal start from $220 and are quoted after the source inspection. Most treatments are completed in a single visit.

Recurring blow flies inside a home almost always indicate an undiscovered breeding source. Blow flies breed specifically in decaying animal matter, the most common Melbourne sources are a deceased rodent, possum, or bird inside the roof void, wall cavity, or subfloor. If blow flies appear consistently from a specific area, the source is usually within or adjacent to that area. Spray treatment alone cannot solve a blow fly infestation while the carcass remains in place.

Small, fuzzy, moth-like flies clustering around drains and sinks are almost always drain flies (Psychodidae). They are around 2–3mm long and breed in the organic biofilm inside sink drains and floor drains, not in the sewer. Treatment requires cleaning inside the drain to remove the biofilm where larvae live, not spraying the adult flies on the wall.

Yes. House flies carry over 100 pathogenic microorganism species including Salmonella, E. coli, Campylobacter, and Shigella, transferred from waste sources to food preparation surfaces. They feed by regurgitating digestive fluid onto food, which transfers bacteria on contact. Blow flies that have bred in animal carcasses carry an even higher pathogenic load. Flies on kitchen surfaces or food are a genuine contamination risk, not just a nuisance.

House flies (Musca domestica) are grey-brown, 6–7mm long, with four dark stripes on the thorax. They breed in decaying organic matter including food waste, compost, and animal droppings. Blow flies (Calliphora and Lucilia species) are larger (8–14mm) with a distinctive metallic blue or green sheen. They breed specifically in decaying animal flesh. If you're seeing metallic blue or green flies appearing inside a room, particularly from a ceiling or wall, there is almost certainly a deceased animal in the structure nearby.

House fly treatment with residual spray reduces adult activity within 24 to 48 hours. Blow fly treatment is effective immediately once the carcass has been removed, without source removal, spray provides only temporary reduction as larvae continue producing new adults. Drain fly treatment using enzyme drain cleaner typically reduces adult activity within 1 to 2 weeks as biofilm is progressively eliminated. A follow-up inspection is recommended for blow fly problems to confirm the source has been fully resolved.
