With spring approaching and the beginning of the warm season, insects start coming out, especially mosquitoes and flies, and they annoy everybody. Moreover, it is easy to defeat insects when you are indoor, the hard task starts when you are outside. For this reason, this is the perfect period to demonstrate the real efficacy of the new Orphea4D Protection, a powerful insecticide spray for exteriors. How? By transforming a normal billboard into a huge insect trap. Transparent glue was applied on a portion of the billboard surface in the shape of the jet spray and when flies and mosquitoes got trapped on the glue, day by day, they made the shape visible.
