I agree with Blane and the ARS.Sorry to say,we have them here in Central
NY.
Last fall the mites dropped into the tray in the bottom of the hives and
were not dead,after inserting Apistan as the lable directed.We observed
for 10 days and no change-NO dead mites.We then inserted coumophos strips
and the mite fall was large and they were all dead.
