I have read on a Slovenian natural beekeeping forum that those transferring foundation bees onto natural comb use flowers of sulfur to aid with varroa issues but then after the bees have build all natural comb they stopped treating all together. According to them bees dont fair well without this Very Soft treatment during the 2 year transition from 5,4mm foundation commonly used there. They also use Perone-style (no frames or top bars) 2 deeps in Warre' size but as one deep box supered with Warre honey supers with top bars or foundationless frames.

I aslo read someplace else that some use Diatomaceous Earth for treating those colonies showing varroa infestation.

Does any one have any more info on this? Experience or links to research?

Im personally dont use any soft acids or miticides but Im not so much against sugar dusting when introducing a new swarm or even new split/or shake down. Hence me asking about these two alternatives in case hell brakes loose in my newly moved apiary to a heavy agri-environment.

Thank you

I would like to know more about how they apply the sulphur, as I can imagine the bees treating it as they would pollen...

The action of DE is as an abrasive: "Diatomite is used as an insecticide, due to its abrasive and physico-sorptive properties. The fine powder absorbs lipids from the waxy outer layer of insects' exoskeletons, causing them to dehydrate. Arthropods die as a result of the water pressure deficiency, based on Fick's law of diffusion. " (Wikipedia)

Given that bees are arthropods, it doesn't seem like a good idea!

I use DE around my feed bins, chicken coop, dust my chickens, cows, goats for pest parasite control. Around the feed bins keeps ants and other unwanteds out. I do put a ring on the ground around my hives to keep the ants out. It does kill insects so I would not use it in a Hive as I am sure it would kill bees. Just my opinion and observations.

Conserving wild bees

Research suggests that bumble bee boxes have a very low success rate in actually attracting bees into them. We find that if you create an environment where first of all you can attract mice inside, such as a pile of stones, a drystone wall, paving slabs with intentionally made cavities underneath, this will increase the success rate.

Most bumble bee species need a dry space about the size a football, with a narrow entrance tunnel approximately 2cm in diameter and 20 cm long. Most species nest underground along the base of a linear feature such as a hedge or wall. Sites need to be sheltered and out of direct sunlight.

There is a spectacular display of wild bee hotels here
