I will end my contribution with these thoughts.

3. If FGMO is only effective for 2 years as Bob has suggested,

What I said was that two years is the accepted time that a hive left
untreated will live untreated before the hive dies from varroa infestation.
Obviously there are exceptions in both directions.

Most  hives started from packages will survive the first winter if the
package did not arrive infested with varroa and there is not a reinfestation
problem occuring.

When you use any IPM method such as drone brood removal, FGMO or screened
bottom boards you knock back the varroa population thus extending the time
the hive can  survive . 100% elimination of varroa from the hive is not
possible  we have been told by researchers.

As time goes on each year the varroa mite load continues to rise as a higher
mite load starts the spring with methods which provide little control and
then you find yourself with a hive at varroa load threshold.

Then control with a IPM method which provides little control will not solve
the varroa problem.

Think about what I have said Kurt as I am trying to  share what  I have
learned about varroa and others on the list already know.

Look forward  to your next post!

Your friend,
Bob
