Bees Flying & Apibioxal

[Spikedog]

As per an earlier thread – Bees out and about today – During week I noted midday temp at 5C all hives very busy but not as much pollen as reported on other thread [We are at some height]. If Bees are bringing in Pollen at this time of year will that allow for some brood rearing? If so and weather continues intermittent mild (relatively) will this impact on the (vaporising) application of Apibioxal – normally applied (by us) on Jan 1st i.e., less than 5 weeks distant. Any thoughts?

will this impact on the (vaporising) application of Apibioxal

No, you trickle it, not vaporize.

No, you trickle it, not vaporize.

Some of the merchants claim for Apibioxal that it can be trickled or vaporised.

Of course, it's only licensed for trickle and at a concentation not optimal for Northern Europe but that's in other threads.

Not heard of that, Alan, rather an expensive way of buying oxalic powder just to vaporize.

But vaporising is more effective in warmer weather, when the bees are not tightly clustered.

Thanks for replies … Whatever the advantages of Vapour -v- Trickle the application is recommended when brood less. Is it likely that Bees still active (perhaps same in coming weeks) and presently taking in pollen have brood? Will the ‘tricklers’ still trickle if bees out and about? For if you trickle we will Vap!

Yes, very likely, well here anyway, but i don't know about your area.

I won't be using any kind of treatment, already done any treatments that needed to be done back in late August and through September, so no more until the same time next year, except of course any i may find that need urgent attention through the active season.

Indeed, a lot of money for a label. This appears to be the English version of the product leaflet, as on a Belgian bee supplies company website. Not dated, but does have the usual marketing contacts and clearly lists vaporisation as a delivery method, obviously a Varrox style device although it's not named:

B) Posology and method of administration by vaporisation
Use an electric resistance device for vaporisation. Fill with 2.3 g of API-Bioxal the pan of the vaporizer. Place the appliance through the entrance of the hiv
e under the bees and to avoid the contact with the honey combs. Seal the entrance of the hive to avoid escape of bees and smoke. To power the vaporizer following the manufacturer’s directions for about 3 minutes (about 280-290°C of final temperature) and Keep the hive shut for another 10 minutes.
Cool down and clean the vaporizer after every use form possible residue (max 6%, around 0,140 g). Use drinkable water for cooling and/or cleaning
