World Manufacturing unit is designed to attract flies in even the most difficult areas to control flies. It is designed for that busy kitchen, prep or food processing area that demands total elimination of flying insects. This unit has a built-in reflector that doubles light output to attract even more flying insects. The NZ 3000 covers areas up to 1,500 square feet. No-Zap fly traps are guaranteed to solve your flying insect problems. Our No-Zap fly traps are safe, silent and effective. Flies and other insects are attracted to the ultraviolet light. There are no zapping sounds, no burning smells, and no electrocuting grid. The No Zap Fly traps use non-toxic glue pads, which are lethal to flies and other flying insects, yet completely safe for humans and pets-no insecticides are used. Sticky pads are easy to install and remove while creating no hazard to the environment. Change sticky pads every 30 days or as needed without contacting the remains of the deceased insects. Our green technology engineering has created the No-Zap fly trap with a very low power consumption (they use about the same amount of energy as a standard fluorescent fixture). Our No Zap Fly traps are constructed of the highest quality materials for a long service life. All of our electrical components are UL listed. No Zap Fly Traps attract bacterial-laden flies away from food prep and food processing areas creating a cleaner, more sanitary food safe environment. All of our No-Zap fly traps come with eight replacement sticky pads (approximately an eight month supply). All of our No-Zap Fly traps are manufactured in the USA.
