Subject: Unapproved Varroa Mite Treatments

Are Mavrik, Spur and other forms of fluvalinate, or formic acid, commonly 
used to treat varroa-infested hives in the U.S.?  I realize these 
treatments are not currently approved for use with bees in the U.S., but 
does the cost difference provide a strong temptation for commercial 
beekeepers?

How widespread is the use of unapproved treatments?  Would appreciate 
learning from any speculation or knowledge on this.

Public or confidential private E-mail.

Thanks,
