Flies are a major risk to food safety for any business handling food, such as hotels, restaurants, supermarkets and warehouses, due to the number of diseases that they carry. Business premises can provide many opportunities for flies to feed, shelter and breed even with strict measures to maintain food hygiene practices.
Our own data from 51,000 customer sites in 27 countries shows that flying insects were responsible for 25% of recorded pest incidents. Independent research commissioned by Rentokil found flies to be the insects most likely to cause damage and disruption to a food services or production business. The research also found that flies are the pest most likely to cause illness in staff.
Electric fly killers are one of the essential tools for businesses to prevent flies from infesting areas for storing, preparing and serving food. Rentokil has developed a new generation of electric fly killers based on years of research into fly behaviour.
The new Lumnia range of electric fly killers are more efficient at catching flies — proven in tests — and also encapsulate the flies hygienically, preventing contamination of food from dead bodies and body parts.
They beat the competition on a number of features. Here are four features that make the Lumnia a better fly killer.
1. Low power consumption
The use of LED UV bulbs in the Lumnia range saves on average 61% of energy usage compared to equivalent products from competitors. As shown in the chart below, some fly killers can consume over four times the electric power of the Lumnia.
Lumnia has three power levels, low, medium and high for different levels of light around the unit. So power usage can be reduced even further when a brighter light is not needed. Each power level can also have an adaptive mode which senses the level of light around the unit and reduces the power automatically if the light level falls, for example at night or when the light level falls below 100 lux.
The attractiveness of light to a fly depends on the relative intensity compared to the ambient light levels, not the absolute amount of light from the bulbs. Therefore at night and in low light levels the power and the output of the LED bulbs can be reduced and still effectively attract flies.
How much running costs can the Lumnia save?
Based on a cost per kilowatt hour of US$0.12 (typical cost in the US) and running for 24 hours a day for a year, each Lumnia unit can save from US$32 to US$94 per year compared to fly killers consuming from 30 to 90 watts respectively.
2. Greater reach of UV light
The horizontal reach of UV light from a Lumnia unit is 40% greater than traditional fluorescent tubes. This gives Lumnia a greater range over which it is attractive to flies while using less power.
The graph shows the envelope of the effective light range, in distance from the unit and vertically above and below the unit. This test data shows that the Lumnia LED bulbs are effective at attracting flies in a much greater space than traditional fluorescent bulbs.
3. LEDs tuned to flies’ eyes
The LEDs used in the Lumnia are designed to emit the wavelength of ultraviolet light that flies can see. So the source of light stands out more in the typical environment where fly killers are placed and attracts them to the unit.
The graph below shows the wavelengths of light that a house fly’s eyes can detect. This shows that the fly’s photoreceptors are tuned to wavelengths around 350 nanometres, which is close to the UV output of the Lumnia LEDs (365 nm).
4. Easy to service
The Lumnia unit has been designed so that it is easy to service. A simple release mechanism lets the unit slide down 30 cm closer to the ground to make it safer to access the unit, while the design allows for easy servicing.
This includes quick changing of the glue boards, glue rolls in the model that has a motorised encapsulation unit, and the LED light strips (which only need to be changed around every three years).
The unit is safe to be placed at head height, so servicing can be carried out while the technician is standing on the floor.
