Yes I can see trembling bees
Is there any way you can move the colony away from the apiary? That would be ideal but don’t panic if you can’t.
Some people might disagree but it’s doesn’t easily spread from hive to hive. CBPV is spread by contact and housekeeper bees get infected by dragging the sick bees out.
1. Give them more space. A super above the brood will help.
2. Minimise housekeeper/ sick bee contact.
If you can prevent the house bees tidying up they may stand a chance
What I have discussed with JBM who first mentioned it and what I have seen a friend do might, just might work.
Have the colony on an open hive stand and remove the floor so that sick bees just drop to the ground
You need to make sure they are not robbed so do something like this
