Flying Insects are known to carry millions of disease causing organisms and have been implicated as carriers of Listeria, Salmonella and E.Coli
By law (1990 Food Safety Act and associated regulation), food that is sold must be wholesome and free from contamination. If you sell or prepare food, you are required to demonstrate ‘due diligence’ that you have taken every precaution against contamination from flying insect pests. These pests are highly mobile and make no distinction between food prepared for our consumption and any other surface that they land on, walk over, defecate on or eat. Many insects have particularly unsavoury habits and therefore represent a high contamination risk to our food.
With this in mind, fly control becomes more than just hanging any old electric fly killer where it can be seen. It’s quality and effectiveness according to type and siting have a real bearing on how much protection you receive. The old adage ‘buy cheap, buy twice’ really does apply to the science of Electric Fly Killers (EFK). Many of the machines we have supplied are still working well after 20 years. Anyone can go to a big DIY store and get a £20 machine that shines a blue light out. However, apart from sub-standard build quality, they’re usually only effective for a year at the most. Why? Well, read on…
So you buy a professional quality, all metal construction EFK from us at Acclaim and you never have to worry about fly control again, right?
Well, not quite. Although the machine continues to work, the phosphors in the lamps degrade over 12 months. This means that, although the light continues to illuminate as far as humans are concerned, no insect-attracting ultraviolet light (UV) is given off by the tubes. Rather like insects can’t see the colour red, we can’t see the ultraviolet part of the spectrum that most attracts flies (usually a wavelength of around 350 nm). So, to us, old tubes may look good…to the insect, they’re no more attractive than anything else.
We once had a farmer call us up and tell us that he needed to buy some professional machines for broiler sheds. He said his EFKs were 4 years old and were no longer catching insects. We asked him if he’d ever had them serviced. He hadn’t. We replaced the tubes, cleaned the machines down and re-sited them. Hey presto, he ended up enjoying highly effective fly control for a price that was about 2 per cent of what he’s been expecting to pay.
Also, if the machine is in an oily atmosphere, the bars will eventually become insulated against insects which reduces effectiveness. If you’ve decided to buy a professional sticky trap machine, the sticky boards will need to be regularly replaced. That is why we include the maintenance of the machine in a service plan for contract customers. Another important things is to ensure that you leave your EFKs open at night. A fairly beefy machine will throw out about 30 – 45 watts of UV light. A shop window lets in, what, about 500 watts maybe? So, as you can see, these machines work best if they’re properly sited away from food, light sources, open windows and doors. We have clever tools to measure the amount of competing UV light so that we site the machine in the best place. It’s not just a case of buying any old machine and fixing it to the wall. What machine you need depends on the nature the business, the size of the room, the room layout and a whole bunch of other factors. That is why you need a professional company to advise and install the machines.
If, on the other hand, you just buy a cheap machine, never get it serviced, cleaned or re-tubed, you may as well turn it off as it’ll be wasting electricity…it certainly won’t be catching flies.
