Regardless of the pests and diseases, the natural seasonal cycle of the honey bee colony has endured. Meaning when they brood, when they do not, when they mass forage, when they swarm, when they slow down, when the cluster tight and go near dormant etc etc. From the ages of old: 10 to 14 day inspection cycle in the spring to manage population size and curb swarming. Zero inspections through the honey flow. One, maybe two, inspection in the fall after the honey came off and just before feeding/wrapping for winter. Perhaps 5 inspections total over the course of a year.
Now due to all the challenges, add shorter inspections of 5 to 7 days in spring, and add 1 late summer check on mite load. No change in fall inspection frequency. Once, maybe twice.
