Mite Treatment and Expansion

The hive that I split a few days ago had varroa mites so in addition to adding another brood box I also treated them. This will go on for about 4 weeks but should eradicate most of the mites. Not harmful to humans at all they can be devastating to the honeybee hive and can weaken them greatly if they get out of hand.
It was about 68 degrees and all the apple trees have been blooming for about 10 days.
