Feral bees have adapted to local conditions and don't need extensive interventions from humans to survive.
The article "Ecological Adaptation of Diverse Honey Bee (Apis mellifera) Populations," provides some scientific contest to the adaptations which make feral populations successful.
These bees have had minimal intervention and they are THRIVING!!! I have never used chemical treatments and there is very little to no use of agricultural chemicals in the 3 miles surrounding my hives!
Honey is one product where you can purchase the best that money can buy. Local honey helps with allergies, I use no chemicals and my bees are out of the way of agricultural chemical use. Because all my bees come from feral colonies, they are well adapted and thrive without human intervention.
