Does anyone have experience with bees under extensive netting.  The 
patch of blueberries I am pollinating at the moment is about six and a 
half hectares under the one net.  I did it in June last year and for the 
last month.  The bees seem to be reluctant to fly on both occasions and 
are going back.   They can get through the walls and with a little more 
difficulty the top.  The reluctance to fly may be no more than very 
little to fly for.

On another property I do in the spring, the bees go gangbusters. They 
fly happily through the nets and are every bit as productive as hives 
outside the nets would be.  The netted areas are however smaller, and 
the hives can be placed just inside the nets.
