Varroa Distructor
Varroa is believed to have been introduced into New Zealand in 2000 and
has since become our biggest problem. Up untill recently the main
method to control Varroa has been with chemicals but as with most of
the rest of the world Varroa is becoming chemical resistant.
So how can we control Varroa? Many other methods are being used as part
of a control method for Varroa. One of the most recent is a special
breeding project to raise queens with a special trait to control Varroa
called VSH ( Varroa Sensitive Hygene ). But even these new queens need
to be combined with other treatments.
List of some other methods
Formic acid
Lactic acid
Oxalic acid
Sugar dusting
Fogging
The use of any unaprooved chemicals is illegal in New Zealand
