Who feeds what and why?

There seems to be a fair amount of beekeepers that do not use treatments and rely on other methods in controlling mites. I'm curious who isn't using treatments and what is their success rates.

We are building a beehive that really is two hives in one. 1. It is an insulated hive that mimics a tree hollows insulation value. During all seasons bees benefit from tree hollows by helping keep hive temperatures more steady. This leaves far less bees on climate control duty and more on hygienic grooming and foraging duty. This is the primary reason insulated hives produce more honey and have less disease. Higher humidity can also play a role in less disease, but that almost needs its own discussion. 2. Beehive monitoring isn’t new but it certainly is gaining traction. What monitoring does, is help eliminate observational error and can give you 24/7 access to what’s going on in the hive. Through integrated beekeeping apps you can also schedule tasks based on schedules or hive data, which means less time interrupting your hives. I’m interested in hearing how you use monitoring or what might be holding you back from using it.
