Re: Applied Apivar today
Apivar will start killing mites on day one. The strips stay in the hive between 42 and 56 days in order to kill all the emerging mites. It is a contact poison, so a bee carrying a phoretic mite must come into contact with the strip in order for it to work. During the course of the treatment you may need to move the strips so that they remain in the brood nest. Also note that you cannot place honey supers on the hives until two weeks after you have removed the strips.
Grab your calendar and mark 6 weeks out for removal and the add the two weeks. Make sure this date is not already well into your honey flow. In my area, April 8th is late for putting supers on.
Thankfully, the bees are smarter than I am. They are doing well, in spite of my efforts to help them.
