There is a great deal less (in terms of milligrams per treatment) of the
active pyrethroid in Bayvarol than in Apistan.  This is primarily, as I
understand it, because the Flumethrin in Bayvarol is considerably more
active than the fluvalinate in Apistan.  It may follow from this that
permissible limits are lower for flumethrin than for fluvalinate?
