This new billboard in Milan for an insect spray also serves as a huge pest strip, thanks to a few layers of aerosol glue. The glue was applied in the shape of an Orphea can's spray arc, which filled in as bugs got stuck in it. The visual effect of that little mosaic of suffering is quite unique, and now all of Milan's summer tourists will see and understand the potency of aerosol glue. And maybe Orphea, too.
