? What is the green bottle fly
Scientific name: Lucilia sericata
Family: Calliphoridae
Order: Diptera
Risk level: High
Category: Flying pest
The shiny green bottle fly (Lucilia sericata) has a bright metallic emerald color and measures 6–9 mm. It is an important pest in meat factories and slaughterhouses. It also has an unusual medical use: its larvae are used in maggot therapy to debride chronic wounds.
Life cycle of the green bottle fly
It undergoes complete metamorphosis: egg, larva (three instars), pupa and adult. In suitable warm conditions, a generation takes 10–21 days. The female lays hundreds of eggs on suitable organic material.
Distribution of the green bottle fly
It occurs in tropical and subtropical regions. In Saudi Arabia, the Gulf and Egypt, it is common in facilities associated with food, waste or decomposing organic material.
Damage and risks associated with the green bottle fly
It can spread contamination in meat facilities. Its larvae may infest open wounds (myiasis), and the fly is a mechanical carrier of Salmonella.
Signs of a green bottle fly infestation
Signs include flies in food or production areas, increasing counts in ILT traps, and larvae at breeding sites.
Where green bottle flies are found
They are found around exposed meat, open wounds, slaughter waste and fish remains. They respond quickly to odors and can reach protein sources within minutes.
Green bottle fly control methods
Use ILTs with regular monitoring, outdoor ULV fogging, residual spraying on resting surfaces, treatment of breeding sources and air curtains at building entrances.
Green bottle fly control products
Pyrethroids (deltamethrin and cypermethrin), spinosad in sensitive areas, and diflubenzuron at breeding sites.
Requirements for controlling green bottle flies in food facilities
FSSC 22000 Version 7/BRCGS: flies are a high-priority pest in food facilities. Their presence in production areas is a Major Non-Conformance. An ILT system with monthly documentation is required.
A fact about the green bottle fly
Green bottle fly larvae are described as the only living organisms in nature that release secretions that disinfect wounds and remove dead tissue with surgical precision. This makes them an approved medical tool for wound treatment in Europe and the United States.
Frequently asked questions about the green bottle fly
Q: How can I distinguish a green bottle fly from a housefly?
A: The green bottle fly (Lucilia sericata) has a shiny metallic green color. Careful visual examination of size, color and behavior can help distinguish the two.
Q: Are ILTs enough to control flies?
A: ILTs alone are for monitoring and do not provide complete control. They must be combined with treatment of breeding sources and environmental management
