An EFK (Electronic Fly Killer) it uses Ultra Violet light as an attractant and then either an electrified grid to zap the fly or a sticky board to trap the fly in which case they end up dead. EFK's operate 24 hours a day, run silent and are very effective at controlling flies in those areas that need to be protected from flies.

Businesses have a duty of care to protect their staff and customers from flying insect pests. The best defence is to have all round 24 hour protection that EFK's give.EFK's will only remain effective if they are well maintained and serviced regularly by a trained and qualified technician. Over time the efficiency of the UV bulbs diminishes and the electric grids become covered in grease.  Sticky boards become full and lose their stickiness.

The UV bulbs need to be changed at least once every 12 months and the units should be serviced at least once every three months, more often in areas of higher infestation. This ensures that they operate most effectively and satisfy the Environmental Health that you have the proper measures in place

There are two main types of EFK's electric grids and  sticky boards.

The electric grid types have electrified meshes that  instantly kills the insect the moment it touches the grid. They are very effective but needed regular servicing.

The sticky board types use sticky boards to catch the flies; once they stick that's it they are dead.  These ones tend to be cleaner as there is no debris, there is no tray to fill up with carcasses (although they have a tray) and you can see at a glance when the boards need changin

These types are more preferable in food production environments and areas where food is prepared and served.
