What is the difference between a high voltage zapper and a glue board catcher?
The main difference between the two types of unit are the high voltage zapper uses a high voltage grid to instantly kill insects as they fly close. The insects then drop down dead into a ‘catch tray’ which will need regular emptying to prevent build up of bacteria. The glue board fly control units use sticky boards to trap the insect as it flies close to the lamps and attempts to land. The glue boards remain effective as long as they have clear glue area free for insects to land on.
