Flies pose a safety risk to any company that processes or prepares food. Restaurants, bars, hotels, supermarkets or department stores, for example, are subject to strict regulations and operational requirements to ensure food safety.

The high number of products, goods, packaging and waste found in and around the premises attract fly infestation irrevocably. No less small are the shelter possibilities for flies.

An independent study commissioned by Rentokil and conducted in 27 countries and 51,000 customer locations showed that flying insects were responsible for nearly 25% of documented pest infestations. Most damage in the production and processing of food was caused by flies. Flies pose a risk for economic loss, image damage and the hygiene of employees and customers.

Fly traps and fly fishing gear are a recognised means for companies to minimise these risks and to keep flies away from areas where food is processed, prepared or stored.

Rentokil has developed a new generation of electric fly traps based on years of research into fly behavior.

The new Lumnia family of flying electric insect traps for small and large businesses is much more efficient at flycatching – proven in tests – and hygienically encapsulates flies, preventing contamination of food by dead insects or their body parts.

Lumnia flycatchers beat the competition on some features. Here are four features that make the Lumnia a better flykiller.

Energy Efficiency

The use of LED UV lamps in the Lumnia series saves an average of 61% of energy consumption compared to competing products. As shown in the table below, some fly catchers can consume more than four times the electrical power of the Lumnia.

Lumnia has three power levels, low, medium and high, providing different light levels depending on the application. This allows power consumption to be further reduced when no brighter light is needed. An adaptive mode measures the light intensity in the environment and automatically adjusts the power when the light becomes weaker, for example at night, or when it falls below 100 lux.

The attractiveness of light sources for flying insects, such as flies, depends on the relative light intensity compared to the ambient light intensity, not on the absolute amount of light. In this way, the power consumption and the output of the LED lamps can be reduced at night or in poor lighting conditions, while still attracting highly effective flies.

Longer Range of UV Light

The horizontal range of UV light from a Lumnia device is 40% greater than conventional fluorescent tube-based devices. This gives Lumnia a greater range, making it attractive for flies – while consuming less energy.

The graph shows the beam effect above and below the unit, as well as the range into the room. The test results show that the UV LED technology used in Lumnia attracts flying more effectively than conventional fluorescent lamps thanks to its greater spatial depth range.

Lumnia UV LEDs are Tuned to the Perception of Flies

The innovative UV LEDs used in Lumnia have been specially developed to emit ultraviolet light at the wavelength at which flies perceive it (as highly attractive). This makes the light source stand out and attract in the typical environment in which fly fishing gear is placed.

The following graph shows the wavelengths of light that the eyes of a housefly can detect. It shows that the photoreceptors of the fly react to wavelengths around 350 nanometers, which is close to the UV output power of the Lumnia LEDs (365 nm).

Greatly Simplified Maintenance

The Lumnia devices have been designed to require very little maintenance. A simple opening mechanism allows the unit to slide approximately 30 cm deeper to the ground, drastically facilitating access and the entire maintenance process. The unit can be safely placed at head height so that maintenance can be carried out while the technician is standing on the floor. The maintenance of Lumnia, i.e. the replacement of the adhesive plates, the LED light tubes and the encapsulation module (in the Pro models), can thus be carried out more conveniently, safely and quickly.

Another advantage: the UV LED tubes of the Rentokil units only have to be replaced every three years.
