I have been meaning to post this for a while now and finally got around to it today..just in time for the wasp season..so here you go.. feel free to ask any questions if you do not understand the pictures..
Several years ago when i got my first colony i was tortured with wasps..i asked advice and Nigel came up with a cracking idea which i modified to suit me..
I had never heard of or seen them before but it was a tunnel entrance attached to the outside of the hive made with various pieces of wood...
After a bit of playing and thinking i came up with this idea for a standard national open mesh floor..
Height and width wise may vary depending where you buy your floors from or if you make your own regarding the full entrance block size..
The tunnel entrance it's self is 100mm wide x 100mm deep into the hive and 8mm high..all the cutting can be done with a good electric chop saw or a good old hand saw and wood chisel...
You will see a small shim of wood with a screw...that is to narrow the entrance down to 50mm wide and other shims can be used to go to a single bee space..
I have made and used underfloor entrances but imho from viewing the entrances and floors of eight colonies over the past 4/5years the tunnel entrances win hands down..not a wasp on this planet can fight it's way through those narrowed down tunnel entrances..these entrances also double up as mouse guards and i leave them in all year but pull them out when the double brood colonies are bursting summer time.
