The first “Insect Electrocutor” was patented in 1932 by American Inventor William M. Frost which utilized an electric lamp in the center surrounded by an arrangement of parallel wires connected to a high voltage electric supply to kill flying insects as they approached the lamp.
Here is one of the original drawings;
Units available today for insect control generally still follow the same basic design….
Introducing NoFlyZone Developed by Jeffrey Moger, a British designer who now lives in Thailand, some significant advantages are now on offer….
Firstly the high voltage grid does not surround the light source and is located well inside the unit. This means that the light output for insect attracting cannot be reduced by any insects if they build up in the grid. This also importantly means that even small invisible parts of trapped insects are retained inside the unit until emptying – Most important for food service applications and kitchens.
Secondly, the light output is not scattered through 360 Degrees around the unit but instead reflected in one general direction, concentrating the light output making it effective to attract insects from a greater distance. The unit can therefore be located further away from target areas, luring insects away while still performing well.
Thirdly the high voltage grid does not consist of parallel wires or bars which due to their close Proximity can quickly become clogged. Parallel grids may also be easily deformed during cleaning resulting in continuous electrical arcing. Instead, NoFlyZone utilizes two curved stainless steel plates which are effective for the very smallest of mosquitoes and flies but also larger house flies with a minimal tendency to become blocked.
This grid is very strong and is guaranteed for 5 years together with the high voltage transformer.
Fourthly the openings provided for light exiting to attract insects are limited in size and designed to invite insects inside the unit while making it more difficult for them to escape. The size and shape of the openings form a pattern which is more attractive than the light source alone and also acts to limit the size of insects able to enter inside restricting access to Bees, Butterflies, Preying Mantis and other beneficial insects.
We are certain that our latest designs offer a big improvement in performance compared with other systems and offer all customers a money-back guarantee if not completely satisfied.
