The Waiting Period for Apistan in honey producing colonies is zero (0) days as
the active ingredient, tau-fluvalinate is hydrophobic - it will not pass into
water or water-based materials from the Apistan formulation. You ARE likely to
get residues in honey however, if the insecticide Mavrik is illegally used in
place of Apistan, as Mavrik is a water-based preparation itself and will mix
more readily with honey.
 
If you're more comfortable in taking the strips out a few weeks before the
honeyflow, that's fine but you should not be wooried about tau-fluvalinate
residues in honey, providing the Apistan strips are used according to label
directions.
