Frequently Asked Questions

Common questions about Sheep Blowfly

Are Sheep Blowfly dangerous?

Yes, they are dangerous to sheep, causing flystrike which can be fatal if untreated.

How do I identify Sheep Blowfly?

Look for metallic green-blue flies with red eyes and a bronze sheen on the body.

How do I control Sheep Blowfly?

Use insecticides, shearing, and management practices to reduce flystrike risk.

How do I identify a sheep blowfly in my home?

The Australian sheep blowfly (Lucilia cuprina) is a metallic green or blue-green fly with a robust body. It resembles other blowfly species but has distinctive bright colouration. If you find a large metallic green fly indoors near a window in warm weather and live near sheep properties, it is likely a blowfly seeking shelter or attracted to organic matter. For direct species identification, contact NSW DPI (https://www.dpi.nsw.gov.au/) or your state agricultural department.

Are sheep blowflies dangerous in Australia?

Sheep blowflies pose minimal direct human health risk. Human cutaneous myiasis from Lucilia cuprina is extremely rare and documented only in vulnerable populations with compromised immune function or open wounds. For healthy households, the risk is negligible. The primary danger is to sheep flocks, where flystrike causes severe animal suffering, production loss, and significant economic cost to farmers. If you have concerns about potential fly-related infection, contact the Australian Poisons Information Centre on 13 11 26 or your GP immediately (https://pubmed.ncbi.nlm.nih.gov/2716619/).

How much does sheep blowfly control cost in Australia?

Control costs vary significantly by farm size and method. For sheep producers, preventative chemical treatments are applied seasonally and incur recurring costs per animal. Jetting — the most thorough application method — requires labour, equipment, and chemical purchase. Breeding for resistance involves long-term genetic selection at ram purchase and offers long-term value. For residential properties experiencing nuisance flies, fly screen installation and maintenance are the principal expenses. Consult a local agricultural supplier or AEPMA-licensed pest controller for current treatment pricing in your region.

When are sheep blowflies most active in Australia?

Peak blowfly activity occurs during spring and summer when soil temperatures exceed 15°C and conditions are warm and humid. In warmer coastal areas and the northern tropics, activity can extend into autumn if soil moisture and temperature remain favourable. Sheep producers must intensify monitoring and preventative measures from September through April in most regions, with earlier onset in warmer areas and extended risk in wet microclimates (https://www.lls.nsw.gov.au/help-and-advice/livestock-health-and-production/diagnosing-livestock-diseases/flystrike).

Should I call a professional for sheep blowflies?

Yes, if you live on or near a sheep property experiencing active flystrike, consult an agricultural consultant, veterinarian, or AEPMA-licensed pest controller to assess blowfly pressure and recommend management strategies. They can advise on preventative chemical selection, monitoring protocols, and husbandry practices. For residential properties with isolated blowflies, professionals can identify sources and recommend screening and organic matter management. NSW DPI provides advisory services and factsheets on jetting, dipping, and prevention (https://www.dpi.nsw.gov.au/animals-and-livestock/sheep/health/external-parasites/blowflies).
