Re: Bottom Board Mite Counts
There are two different types of sticky board mite counts.
First one, and one thread started with is daily dead mite drop. Our Apiarist advises to total dead mite drop over a three day period. If total drop over three days is 30 or more, then mite reduction is in order.
Second sticky board count is dead mite count after a treatment. Treatment is often OAV or Apivar. With OAV, do a three day dead mite drop total. I like to see the three day dead mite drop below 30 before I stop doing treatments 4-7 days apart. ????My understanding is that dead mite drop occurs over a longer period of time with Apivar so one would need to do a total over a week or two.
I do not do an all season long sticky board mite count. I choose to do an early spring, 42 plus day Apivar treatment, a late August-early September OAV and a dead mite count to determine follow up OAV, and then do a late October/no brood, one or two treatment with OAV. My three day dead mite count after OAV in early September was less than 10.
