here's how I look at things.
I am a technician turned beekeeper, turned pest management tech.
one of the biggest thing in solving insect "problems" is understanding their harborage.
some insects seek out moist, humid locations.
some seek out cool moist places.
honey bees seek out dry, warm places.
I believe that if we as beekeepers can help the hive be as warm and dry as possible, that leaves the bees in a better place to handle nest control issues themselves.
if the hive is doing a lot of the work of staying warm and dry, the bees don't have to work as hard at fanning to cool down or increase heat in the hive. Nor do they need to work as hard to control the air flow to remove humidity moisture in the hive.
by not having to do that much more work, they conserve food stores and have more energy to maintain healthy immune systems, patrol the nest for pests and parasites, etc...
This is just my thinking (influenced by historical beekeepers like Emile Warre, Crist and others who thought similarly) and so I am working to build hives like this to allow bees to do what they do best. Which is colony/nest management.
