I treated my two hives yesterday with formic pro. I opted for the two week treatment
which calls for two strips. Both hives were in good shape with a great spring and summer
so far. I followed directions and removed the entrance reducer for adequate fresh air.
This morning I discovered that one of the hives has had a bit of a die-off. There's some bees in the grass in front of the hive, and I can see a handful more on the screened bottom. Bees are busy removing the dead. Am I correct in the understanding that the treatment does come with a small mortality rate for the adult bees and I shouldn't be too concerned? Thanks
