The grids have 3 rows at the bottom, while laterally the bee passage goes up.A rib on both faces of the grid, at the holes and beyond, allows the bees to cling to then pass more easily.If at the placement of the trap on the Beehive, the pollen collector plate is left open, it makes it easier for the bees to recognize a new passage, reducing once it is lowered (closed) any engorgement.A very wide slit, before the pollen collector tray, allows the bees to remove dirt from the Beehive.Two side holes serve as drones passageA very wide roof provides good shelter for the trap from the weather.
