My small apiary (in Victoria, Australia) is suffering from the unwanted attention of a large number of wasps, known locally as European Wasps but elsewhere also as Yellow Jackets. In my search for solutions to this problem that threatens the viability of the apiary, I have come across a few words and one diagram in a book "Practical Beekeeping" by Chapman-Taylor and Davey about a New Zealand device called the "I.W. Forster wasp baffle". I would very much like to get some more detail on the actual construction of the baffle and on its concept of operation. Could anyone please help me with details of the baffle or point me in the direction of a source of such information. Advice on the effectiveness of the device would also be much appreciated. ________________________________ Paul Hooper Canberra, Australia .
