Paul Diehl, who also teaches a beekeeping class for Arlington Community Education, brings thousands of bees up from Georgia every year to re-populate the bee hives in Arlington. He has had major losses in his hives over the past two winters. Diehl’s hives are evident all over Arlington — in backyards, under trees, next to garages. He applauds local residents who keep pesticides and chemicals in the yard to a minimum to help keep bees healthy.
