How do you apply oxalic acid?

[MrPea]

Do you dribble it along the top of the frame (along the wood) or down on to the bees?

Is it too late to do it this year?

 

[VEG]

down onto the bees in between the frames it is known as a seam of bees.

 

[VEG]

Better late than not.

 

[MrPea]

Does it not harm the bees? I'm so scared of doing it - last year I dropped it down on to the bees and a week later the entire coloney was dead.

 

[VEG]

Tis up to you if you want to do it. I treat all my colonies others dont use it. You will get many reasons for and against, in the end its all down to you.

 

[Easy Beesy]

Get someone more experienced to do it for you the first time. Observe closely and you can do it yourself next time

It coes not kill, if you do as it is recommoended

40 ml macimum to one box hive and 50 ml to douple brood.

4 ml maximun per one bee filled frame gap.

Dead hives has not been reported in trickling. Except one guy. He made 10 times stronger than recommended and he killed his all 12 hives.

I Vaporise it...... never too late, in fact part of some experienced beekeepers IPC and can be carried out on newly collected swarms
Ideally oxallic should be used when bees have no brood so that varroa mite has nowhere to hide!
But all this is well described on Dave Cushman's site.... worth a look

 

[Luminos]

I did mine a few weeks ago - first time - they're still alive...

I made my first treatments 2003. I remember how I was afraid what will happen to hives. Nothing happened. It only killed mites.

Propaganda around this issue is enormous.-

What's an Car accumulator? Is that the battery?

There's one on fleabay at the moment
"Vaporiser Evaporator treatment bee / varroa mites Beekeeping electric tool"
Looks different to the DC page one.

Which do you have?

Oxalic Acid vapour is very bad indeed for beekeepers.
*Great* care must be taken to avoid inhaling it ...

Trickling (like vaporising) can also be done at any (other) time that the bees are broodless, as with a newly-collected swarm. As indeed can any other treatment that attacks the phoretic (outside the bee pupa's cell) mites - like dusting.

Would it not make a swarm abscond? Or are they too sugary to care?

 

[Black Comb]

I usually put a queen excluder under the brood box when i hive a swarm
Stops them absconding, whether I oxalic or not.
Take it off after 4/5 days.

simple use a good quality respirator. handle with respect, no problems. New vaporizer arrived today from Sublimox Italy now i can treat a hive in 25 seconds with far less disturbance varrox applicator

Agree with that... also give swarms a 1:1 feed with a dash of HM's thymol

Sublimox Italy......

At this point in time Finnman will be reaching for the ROM !

Vaporised oxallic acid AND 220V AC !!!!
I would get some very thick rubber gloves and a thick rubber mat to stand on!

No use for me tho... Don't have a Fiat or Italian bees.....


... except for a few NewZealands that seem to show cleanliness towards varroa ...

Beware the cheap vaporisers on fleabuy.. Eastern European imports, tend to fall apart after a few heating cooling cycles.. from experience.

It happens.

I have sprayed, sublimed and trickled in the past. Not done it at all in the last few years with no colony losses due to varroa. According to Beecraft's Wally whatsisname , not needed in 90% of the time for winter survival. There are other treatments for other times of the year. But your choice. I have made mine - it is available if needed, but not often used.
