- Remove frames containing brood from the brood box one at a time.
- Give the frames a short sharp shake, while holding them over the box they came out of. This will remove the adhering bees and ensure the bees go back into the same box they came from.
Once the frame is free of bees, inspect each capped cell to ensure:
- There is a solid laying pattern (as opposed to a "spotty" pattern).
- The capping colour is not overly dark and is the same or very similar to that of the capping of cells immediately around it.
- That the texture of the cappings is more "fluffy" than greasy.
- That there are not irregular perforations or holes in the cappings.
- That the cell cappings are flat or domed and not sunken.
- If any cell displays one or more of the above symptoms, it should be uncapped and the larva exposed.
- The cap can easily be removed by scraping it away with your hive tool or a dry grass stalk.
- Once exposed the larva needs to be closely examined (return to the main App for instructions on how to do this and what to look for).
