RoSH update on UV tubes: Impact on Food Businesses

The European Commission's (EC) updated Restriction of Hazardous Substances (RoSH) Directive 2011/65/EU has phased out the use of various fluorescent lighting (from September 2023 in the UK) due to hazardous mercury content. The updated RoHS Directive is important for food businesses that still use fluorescent UV tubes in fly killer units. Since these tubes contain mercury, their long-term use is being phased out across the UK and Europe.

The excemption on fluorescent UV tubes used in electric fly killer units is due to end from February 2027. (However, that time frame could be extended if the lighting industry submits a renewal request to that excemption period). Effectively, after the excemption date ends fluorescent UV lamps will no longer be available. However, the direction of travel is clear, and businesses should plan ahead. Which means that the traditional fly killer units many UK businesses have relied on for years are no longer a viable, long-term solution.

Once the exemption ends, replacement fluorescent UV lamps may become hard to source or unavailable. Therefore, older fly killer machines that rely on this technology may become costly to maintain. For food businesses, this creates both a compliance issue and an operational risk. A move to LED fly control can reduce disruption while also supporting hygiene and energy goals. Moreover, mercury-free LED units offer a more future-ready option for indoor fly control in commercial settings.

Future Proof your Fly Control

It's time to transition from existing traditional fluorescent UV tube fly killer units to modern, mercury-free Lumnia LED fly control units. Future-proofing your fly control means moving away from fluorescent UV units before supply and compliance issues affect your business.

Since mercury-based tubes are being phased out, LED fly killer machines offer a more secure long-term option for indoor fly control. This not only helps your business comply with new regulations in the future but also offers a more cost effective and more energy efficient way to protect your business now from fly infestations.

While older systems may still work today, switching earlier gives you more time to choose the right electric fly killer for your environment. Therefore, an LED insect light trap can support both daily hygiene standards and future operational planning.

The Reality of Electric Fly Killers: Pros, Cons, and Smarter Alternatives

Standard electric fly killers rely on long-wavelength ultraviolet light to draw in flies before dispatching them with a high-voltage grid. While effective, these traditional zappers are strictly designed for indoor use; placing them outside needlessly attracts harmless insects like moths.

However, standard traditional zappers carry a significant hidden risk indoors. The electric shock causes insects to explode, scattering microscopic particles—known as "blow out"—into the surrounding air. This aerosolised debris can easily contaminate nearby foodstuffs, drinks, and preparation surfaces, or even be unwittingly inhaled by staff and customers. For any business handling food or prioritising hygiene, this creates serious health and safety compliance hazards.

To eliminate these risks, our Lumnia LED fly control range takes a cleaner, smarter approach. By combining energy-efficient LED technology with specialised glue boards and encapsulation design, Lumnia captures and holds flying insects whole. This completely prevents fragmentation and blow out, ensuring your space stays hygienic, compliant, and significantly more energy-efficient than traditional units allow.

Electric Fly Killers FAQs


  • What is an electric fly killer?

    An electric fly killer (EFK) is a commercial pest control device designed to eliminate flying insects in hygienic environments like commercial kitchens, restaurants, and hotels. By attracting flies using ultraviolet (UV) light, these units neutralise pests via an electrified grid or trap them on adhesive surfaces, protecting food preparation areas from contamination from flying insects such as house flies, bluebottles and other fly species to help keep food areas within the premises hygienic and pest free.


  • How do electric fly zappers work?

    Electric fly killers attract flying insects using traditional UV-A light from fluorescent tubes (as they contain mercury, their long-term use is being phased out across the UK) or energy-efficient LED bulbs that don’t contain mercury. Once lured inside, traditional units electrocute pests on an internal high-voltage grid. More modern glue-board models capture flies on replaceable adhesive sheets, while advanced encapsulation systems hygienically roll and seal insects and fragments within an automated film.


  • Where is the best place to put a fly killer unit?

     All electric fly killers have a ‘coverage rating’ which indicates the maximum room area that the unit will effectively operate within. If the area that needs protecting is larger, then more than one fly killer unit will be needed. There are other considerations to take into account when positioning a fly control unit:

    • The most effective location for an electric fly killer is between the most likely entry points for flies (i.e. doors, windows) and the food - as flies are lured away from food areas without being attracted further into the premises. Ideally 1.5 to 2 meters above the floor where flies naturally travel. 
    • Insects are attracted to bright lights, so zapper units must be kept away from other light sources that could compete for the flies’ attention and reduce the effectiveness of the unit.
    • Ensure insect debris (blow out from electrocuted flying insects) does not land on food or food preparation areas if using a basic electric zapper, which could cause contamination – so do not place units above food areas. Using encapsulation fly killers like Lumnia and Lumnia Ultimate greatly reduces risks of contamination from this type of fly fragmentation, offering greater flexibility when positioning units.
    • Most flying insects will enter from outside, so it’s vital not to place fly killers directly facing doors or windows, which can entice more flies to enter. Using Rentokil external Fly Box alongside Lumnia indoor units provides greater fly control protection as many flying insects are eliminated before they have chance to enter a premise.


  • Do LED fly killers work?

    Yes, LED fly killers are highly effective. They emit focused ultraviolet (UV-A) wavelengths that attract flying insects while consuming significantly less energy than traditional fluorescent bulbs. Modern LED units also boast longer lifespans, reduced environmental impact, and consistent UV output, making them a reliable and cost-effective long-term solution for commercial and residential pest control.


  • Are UV light fly traps safe?

    Yes, commercial and residential UV light fly traps are safe when used as directed. They utilise low-intensity UV-A light, which poses minimal risk to human skin or eye health under normal operational exposure. For food-handling areas, non-fragmenting glue-board models are recommended over high-voltage zappers to safely contain insect fragments without hygiene risks.


  • Are light traps effective only for flies?

    No, UV light traps attract a wide variety of phototactic flying insects, including moths, gnats, midges, and wasps. However, their effectiveness varies by species; biting insects like mosquitoes are drawn primarily to carbon dioxide and heat, making UV light traps far less impactful for total mosquito management than for general fly and moth control.


  • How to get rid of flies in a commercial building?

    Implement an integrated pest management strategy combining physical exclusion, sanitation, and monitoring. Install air curtains, door screens, and strategically placed UV glue-board traps to intercept pests. Maintain strict waste management, deep-clean drain lines, eliminate standing water, and schedule routine professional inspections to address fly breeding sites and comply with health regulations.


  • Can you use fly paper in commercial kitchens?

    DIY fly control products like fly paper, whilst effective at catching flies in the home are not suitable for commercial kitchens as they are not designed to cope in such an intense business environment and many contain insecticides which are not suitable for commercial kitchen environments.
