Align inspections with your management practice
While the frequency of AFB inspections alone can have a significant impact on AFB levels, there are certain beekeeping management practices where failure to identify a diseased colony greatly increases the chance of other colonies becoming infected.
The practices almost always involve transferring things (such as frames of brood, frames of honey, honey supers and bees) from one hive to another.
Inspections should always be targeted to times when these management practices take place. If hives in an outfit or apiary have an AFB problem, a complete brood check should be done before anything is removed from any hive.
Inspections should be carried out immediately before removing bees, honey or equipment from a hive.
