Celotex insulation

[user 6228]

Thank you, I have a cedar hive and I have made it from 25mm celotex as well as having 25mm on the crown board. I live on top of a hill in North Wales which gets very windy so hopefully this should help them. Thank you for all your replies. There were a few fanning at the entrance today, maybe I should open the top entrance to allow circulation? I have a mesh floor and my entrance is reduced to two bees on the width.

Providing the bees have an open entrance and are not crowded they don't need any addition ventilation. Think about a tree. It doesn't get any thinner or sprout extra entrances for summer.

I've been putting insulated hive covers on for a few winters now, and I'm sure it makes a difference.My hives are situated in a spot that gets blasted by the winter gales and with the amount of rain we get this all contributes to chilling the hives making the bees life that much harder. My covers are made to be a very loose fit which allow the hives to get some flow of air. Held down with a ratchet strap.They come off when the weather warms up in the spring.

I. My covers are made to be a very loose fit which allow the hives to get some flow of air. Held down with a ratchet strap.They come off when the weather warms up in the spring.

But that "some Air" is a mistake,

If you have a mesh floor, no entrances or Air flow should be in upper parts.

With solid floor upper entrance in the Wall is good, but when you have not snow on Britain, it is better to be without.

Bees take care about their ventilation. Help is not needed.

Derekm - with the improved thermal insulation that your cosies provide, do you find you ever get a brood gap in winter? Just thinking how this may affect those who choose to use oxalic acid over winter.

Warm hive box has nothing to do with brood gap.

yes there is a brood gap then, but you also get them when there is a forage shortage, even seen one with a sac brood infection.

winter brood gap appears to have nothing to do with nest temp or clustering.

your problems with oxalic will be

1) the bees wont be clustered
2) the oxalic may be more toxic to the bees - i dont know because we dont use it anymore.

You do not know but you are delivering rubbish

Bees will cluster and hives have no problems in their build up in spring.

There are huge amount of research during last 15 years and experts here tell their feelings.

(oh dear)

If you do not use OA, it has no evidence value. And you say yourself a scientist.

Oxalic and other varroacides are not tested for toxcity in highly insulated hives, and not even in polystyrene hives according to Vita Europe (a couple of years ago). So i have to say the possibility of higher toxicity exists but I cant say for certain it does or does not occur.

Gooooooh heavens! How do you know that all!

You have only highly insulated hive on the Earth. Don't worry.

Even polystyrene ... you cannot say certain,

1998 started European Union Varroa Group, and it got its work ready 2006.
Huge amount of hives on different parts of Europe and guys calculated mites' deadrate in different conditions and with different stuffs.

IT seems that you give no value to Real researrchers' work.
All modern varroa control works are based on that work 15 years ago


There was a Finnish reasearcher Seppo Korpela in that group. He had 100 own hives and 150 researsh centre hives. He went to study beekeeping to Californian University about 45 years ago.

Korpela was in that varroa Group, and he overwintered his bees in polyhives.

We have some really big beekeepers, who all use oxalic acid in Winter

Seppälä & Komppa 1500 hives
Honey Paw company 1200 hives
Honey paradise 3000 hives

Those all have used oxalic acid since trickling was invented.
Seppälä is our varroa expert, and in another diseases too.

Those guys cannot run business if they use false or harmfull methods.

They are marketing their own stuffs, they are not that stupid that they do not know what has happened in Europe.

And in Britain so called experts are in same chorus, when they say that you cannot make your own oxalic stuff..

Britain did not participated to the EU Varros Group, even if it had reserved a site in the group.

have they done a full toxicology study on their varroacides in polystyrene?

 

[Finman]

And what is that?

Who......what varroacides,

What means full?
Your demands or what?

OA trickling is used on Mediterrinean countries, where day temps are sometimes 40C

IT was invented in Italy.

What is polystyrene?

From wikipedia.... IT is one of the most used plastic.


British beekeepers have painted their hives with creosote.
Have those guys made full toxicology tests?

Read creosote from wikipedia. IT is interesting. Quite wast variety of.... Something...
