Tunnel with a built-in 5.1 mm pollen grid for NICOT full-ventilation floors. It works with the NICOT pollen drawer, which is sold separately.
It does not replace the floor: it sits on the one you already have and turns it into a pollen trap in a minute, with no tools.
01 · YOU NEED TWO PARTS
The tunnel is only half the system: on its own it knocks the pollen off but does not collect it. Underneath there has to be the NICOT pollen drawer, sold separately, which is what holds the harvest. It is the first thing to check when ordering, because without the drawer the pollen ends up on the floor of the hive.
02 · HOW IT TAKES THE POLLEN
Coming home, the bee passes under the tunnel and then, of necessity, through the 5.1 mm grid. The loads come off before and after she crosses the holes, fall through the ventilation holes in the floor and end up in the drawer. The perforated section is cut to the exact length of the drawer, so no pollen is lost off the sides.
03 · THE DRONE ESCAPES
A drone does not fit through 5.1 mm, and a trapped male ends up blocking the grid. That is why the tunnel has two 9 mm escapes at the ends: uncover one and the drones leave that way without spoiling the harvest. It is the detail that separates a pollen trap that works for a week from one that jams on the second day.
04 · ON AND OFF IN A MINUTE
It sits on the full-ventilation floor and comes off by levering with one or two hive tools. That ease is what lets you work the way you should: a pollen trap goes on in stints, during a good flow, and comes off again — because it is taking protein from the colony. And the drawer is emptied every 24 hours: in heat and damp, pollen moulds the same day.
