It is an invasive technique, but disruption can be minised by: 1. have everything you need to hand before you start 2. don't lift any frames out or disturb the bees by smoking
3. replace the crown board and roof as quickly as possible when finished.
Suggest you also heft the hive after oxalic acid treatment to check winter weight
