Hardware cloth
« on: March 08, 2023, 10:13:44 am »

People are often talking about various sizes of hardware cloth.  Here is a list of the sizes and uses in beekeeping:

 The #x is how many wires there are to an inch of hardware cloth. So #4 has four wires to the inch. Sometimes called 1/4" hardware coth. The openings are the # minus the thickness of the wire.
What hardware cloth to use

    #8 - no bee can pass. pollen gets stuck but you can sometimes shake some through.
    #7 - as long as there are no bent wires, no bee can pass. Pollen falls through. Good for the bottom of a pollen trap to let the pollen fall into the tray.
    #6 - worker bees can squeeze through (and will) but they have to wiggle and squirm a lot. Drones and queens cannot.
    #5 - worker bees can squeeze through easily but lose some of their pollen. Queens and drones cannot. Good for a pollen trap to force the workers through.
    #4 - all bees can pass (workers, drones and queens). The workers sometimes lose some of their pollen when they catch their basket on the wire. (mice cannot and this makes a nice mouse guard)
