Insects like mosquitoes and flies can be quite a big problem in the Northern hemisphere—especially during the warmer seasons.
To help combat the flying pests and promote its brand of insecticide, ORPHEA created a billboard ad that traps insects.
Transparent glue was applied on the ad’s surface in the shape of a jet spray coming from an insecticide can.
As time passed, flies and mosquitoes got trapped in the glue, making the jet spray shape visible.
