> Are these directions similar to those provided for Bayvarol? I quote in part from the 'Bayvarol' leaflet:- Each strip contains 3.6mg Flumethrin Normally developed colonies recieve 4 strips Nuclei and young colonies receive half dose. Large colonies with several brood chambers receive 4 strips per chamber Best efficacy is to be expected when used in late summer after the honey harvest. Ideally the strips should not be used during peak honey flow periods. However, Bayvarol can be used at any time of the year for diagnosis or in severe infeststions where there is a threst to the survival of the colony. Diagnosis. 24 hours Treatment - six weeks. > Yours Ian [log in to unmask] - Northern Regional Bee Inspector, UK - Bee Curious phone/fax 01704 822831 snailmail 'Asland' Flash Lane, Rufford, Ormskirk, Lancs, L40 1SW - UK.
