Re: Validity of Mite Drop Test
Whatever manner you use to determine as best you can what your varroa infestation level is like you have to compare results over time. Take a number of samples and readings. Is Hive A showing more mites per sample than Hive B? Is the sample taken today higher than the one taken last month? Does the sample taken today show a number of mites which makes me think it's time to treat?
One sample doesn't tell you much until compared to other samples taken at the same time or compared to samples taken at this time last year. If I sample my hives, prefer the ether roll technique, and see 3 mites, then I am not worried about that hive. If I see 10plus, then it's time to think about treating. Unless honey is being produced.
The time of year makes a difference too.
