Encased in solid metal with catchment tray, this Eazyzap Commercial Fly Killer is perfect for keeping areas free from unwanted pests such as flies, with two 8 Watt ultraviolet tubes.  The highly visible tubes attract pests which then fall into a removable tray so you can easily dispose of them,  maintaining a hygienic environment.  To maintain optimum efficiency, bulbs should be changed every six months and are available separately.  
 
The fly killer can either be attached to your ceiling using the chains provided or the unit can be set on a solid surfact such as a shelf.
