Re.  VTD (Varroa Treatment Device) - Popodi Developments.
 
    For some time now, we have read various promotional articles about this
    plastic device.  In every case, it claims highly effective against Varroa,
    safe to use, and University tested.
 
    Well, I have not seen any independent scientific information confirming
    these claims.  Let the unnamed US university publish its findings so that
    beekeepers can make up their own minds about the VTD.
 
    Also, I remain concerned about a device  described as 'safe', whose
    operation depends on the use of 85% formic acid.  It is on the fringe of
    mis-information because handling formic acid carries some potential hazard
    to the applicator and bees.  It doesn't mean formic acid should or could not
    be used in beehives, but beekeepers must be fully aware that formic acid
    (even at the standard 65% concentration used in Canada) is hazardous and
    must be handled with care.
 
    I sincerely hope the VTD is as effective as it claims to be but instead of
    having a promotional ad on the Bee-L, why not distribute and publish the
    field trials of this mysterious US university substantiating the efficacy of
    the product?
