I've just sampled my hives for Varroa, finding 2 or fewer mites per 100
bees.  While me feel for this issue is that this level is too low to
treat, I don't have any data or expert opinion to base my decision on.
The April '92 issue of Gleanings suggests that 30+ indicates a hive in
danger of collapse, but doesn't give much help at lower levels.
 
How about it, folks?  What infestation level indicates that it is time
for the Apistan?
