Nosema

[susbees]

When the weather improves and lots of pollen is going in the forecast is good, I would do a shook swarm and then feed thymolated syrup which has been shown to reduce the rate of transmission.

Adapted Bailey comb change using dummy boards and an upper entrance is far less stressful. And more stress they do not need...

The reason I suggest shook swarm rather than Bailey is because if nosema is bad it is likely to be contaminating quite a lot of the comb. I do agree that it is stressful for bees, especially if the temperature drops and they can't get any pollen. In cooler temperatures it makes it more difficult for them to keep warm and to build comb too. I suppose it depends how reliable your local weather forecast is.

I lost some perfectly health colonies that I shook swarmed last year due to the weather turning bitter and wet. I was left thinking that I would only do shook swarms if I saw disease.

One of the problems with shook swarming Nosema infected colonies is that it stresses the bees and after shaking they tend to defaecate over the new clean combs of foundation and the disease breaks out big style. Also infected bees not only have problems producing brood food but also no good for secreting wax to draw the combs. If carrying out a Bailey best to use clean drawn combs.

Shook swarms are not meant to treat nosema. It is a disaster to the colony.

AFB is only disease where shook swarms are recommended.

I do not count hobby beekeeprs' recommendations.

.AFB is only disease where shook swarms are recommended.

It's recommended for EFB.

It's recommended for EFB.

Most of countries recommend to change the genepool of bees in EFB case.
