If you’re looking at taking your honey off you’ll be looking at clearing the bees. If you’re in a hurry and you like a fight you can always shake them or brush them off the frames but if you favour something slower and less brutal you’re looking at a clearer board.
All clearer boards employ some species of a one-way bee-valve. Generally speaking – the faster they clear bees – the faster the bees will find their way back up again.
Porter bee escapes make for a slower clearer board but correctly set they will not allow the bees to get back up again. Unfortunately they often get a bad press but if they are set up carefully and a few precautions are taken to maximise success – they’re brilliant.
This is a Porter Bee Escape (Click photo for a close up):
By the way, when a Crown Board has Porter bee-escapes fitted it becomes a Clearer Board. When you take them out it’s a crown board again. There’s another advantage: – other clearer boards are just clearer boards – full stop.
How to Succeed
- The top of a Porter bee escape is the side with the round hole in it – this is the side that needs to be uppermost into your crown board;
- Make sure the top bars of the brood box are clear of brace comb etc which may block the bee escape exits;
- Make sure the bottom bars of the super frames are clear of trailing curtains/projections of comb etc which can block the bee escape entrances;
- Ideally your crown board should have a bee space top and bottom otherwise the entrance or the exits can easily be blocked or narrowed;
- Make sure the holes in the crown board are not too tight – if the bee escapes are nipped from the sides the metal springs tend to close up and prevent passage of bees;
- The top plate slides off a Porter bee escape (see photo above) so you can set the springs inside or clean it. Set the metal springs so the space between them is about 3mm – use yer loaf here – it needs to be wide enough to allow a bee to push through but narrow enough prevent it from returning.
- Most crown boards are equipped with two openings for bee escapes/feeders – one in the centre and one offset. Don’t place the board so one escape is over the centre frame and the other one is over an outer frame like this:
Because the smell of the brood nest will only be wafting strongly through one hole.
It works better if you place the board so the escapes are perpendicular to the brood frames and both are lined up over the centre frames – thus:
This way, the bees will be drawn like Bisto kids through both escapes by the smell of the brood nest.
- Be prepared to wait for at least 24 hours. Ideally, if you were to put them in in the morning they should be clear by the afternoon of the following day.
Reasons for Failure
- Drones in the supers – these fat boys will either get stuck the escapes like Winnie-the-Pooh in the rabbit hole and bung up the works or will simply gang together and refuse to even try. Drones will bung up any and all alternative clearer boards I know of.
- Queen in the supers – if your queen is in the supers bees will not clear. In fact it is the scent of the queen and brood in the brood box that draws the bees down from the supers;
- If there is brood in the supers – even if the queen is in the brood box – the nurse bees will not desert the brood and the supers will not clear;
- If there is unripe honey in the supers, the honey processors will stay on at work and slow the clearing process. However, if you wait for 48 hours even these bees should have cleared. If you put clearer boards in in the morning the honey brought in the previous day should have at least part-ripened overnight;
- If your supers or roof are not bee-proof your supers will fill up with robbers as quickly as the resident bees clear;
- Some people will stack all of their supers together on a clearer board on a separate stand/s. This sometimes works but if there are a lot of young bees in the supers they will either not clear at all or they will be hanging underneath in a sad clump not knowing where they came from or where to go. That’s my experience anyway.
