The hive which has had 5 vapes was checked Monday and another <250 dropped, they had a 6th vape.
Will check the insert tomorrow, I can only think they re now bringing them back from some where ?
Looking an my numbers and dates, my other 3 hives all saw an increase sometime around the 4th-9th of this month.

I took 650 (yes exactly 650) bees from my most infested hive on 16/6/2020 and sold them to men in white lab coats so they could be experimented on :patriot:. I was told that not a single mite was found.

I started vaping 70 days later and you have seen the results.

I don't know why but I always imagined hives getting infected with 1 or 2 mites, then slowly spreading. But it seems hives can bring home huge numbers in a short period.

In both our cases, it must be bees robbing from a dieing hive as others have said, I cannot imagin any other way so many mites could get into a hive so quickly.

I know you did, but, "I didn't listen".

I vape 2 hives one day, then 1 hive for the next 2 days then have a break and start again. So have done myself no favors with a crazy schedule - don't ask.....

I probably should have ordered some Apivar and put it in all 4 hives when you said.

But figure I have got this far with the vape, so will probably just slog it out now.

The numbers are finally significantly decreasing in H1, so if that holds up then at least the end is in sight.

Definitely got an eye out for a gas gun. If I gunned all 4 hives on the same day - life would be simpler.

I am considering getting some Apivar in case the next few vapes don't go so well.

But to be honest, I prefer a treatment that does not require opening hives, or keeping the inspection trays in for extended periods. So am very fond of the OA approach and "want" it to work. That is why I have been hesitant to follow your advice on this occasion.
It’s a handy thing to have and I do keep some strips in the freezer. It’s a wise thing to look into your hives one last time after treatment before they go into winter anyway. The other thing you can use is oxalic strips and simply leave them in there.

I've never used Apivar, always OA. Please explain why abandoning a course of OA in favour of Apivar solves the "problem". What problem?
Surely if huge numbers of mites are dropping, it is doing its job.

I'm not trying to be difficult, it is a genuine question.

I agree if OA vaping is producing mite drops then yes, it is working.
Following the first vape most phoretic mites should drop within 5 of 6 days, after that three further 5 day vapes should catch the immerging mites in any emerging brood cells. Huge mites drops after the course of treatment must come from elsewhere.

It depends whether you can be bothered to keep vaping. Simple as that. If you don’t mind going back and back till the drop us acceptable then do it. My suggestion was for an easier life.

I assume you are referring to madasafish`s comment.

I though the problem he meant was the high mite count and the fact many more vapes may still be needed. (a familiar situation....)

Dani says its "whether you can be bothered to keep vaping". It not just a question of effort.

With days getting shorter and work commitments, it can become hard to find time. Luckily my hives are in my garden and I only have 4. If you had to deal with more hives, travel time and multiple locations, then I see how OA can become a real headache.

Although like you I favor the OA approach, I can see why some don't like it.

We are using apiguard on our two hives, the first hive dropped 244 after 12 days, the second hive dropped 809,we were a bit shocked by this number, we are on the second pack and so far the second hive continues to be high 329 after the first four days, if this continues to be high do we need to do any other treatment at the end of the second Apigard?

Hi Nannysbees, Welcome to the thread. Please feel free to continue updating your progress here.
It will be interesting to see how others are getting on with different treatments.

It depends partly on your pest management program. But assuming you are undertaking an autumn treatment as part of that program like me. Then ideally you want to reduce the mite numbers to such a level they pose no further immediate threat to the hive. I do not intend to treat again until just before the supers go on.

I am not especially familiar with Apigard and have not used it before. Does it require a certain temperature to work? If so consider an alternative treatment should the weather catch you out.

Check the manufactures guidance to to ensure it is suitable for prolonged/repeated use. If so, and you are happy with the treatment then I would continue.





This is the 48h drop, too lazy to count today.

Sorry if this question sounds daft, but what color are V-mites? I thought they were a dark red/brown color, but keep finding some lighter, almost orange ones, and few that are almost see through like they may be shed skins. The one in the picture is still alive too, is its color normal? Are these younger mites maybe?

You should be ok. The treatment period is six weeks.

Varroa mite mature adults are dark brown, the very young ones are very pale with various hues of colours in between.

Drones move between hives. Varroa mites prefer to lay in drone cells..
Lots of robbing just now.

Take that combination and you can see why 4 x 5 day vapes or 2x Apiguard over 4 weeks may not kill all mites.

But insecticide strips are usually meant to be left in 6 weeks...

I usually use thymol based products (or MAQs).. but when you have big and prolonged mite drops, the best answer - in my view - is Apistan or Apivar.. or Apitraz - strips left in 6 weeks.. They also work better in cooler temperatures.. which is important outside the Southern most parts of the UK /not warmed by the Gulf Stream . Temperatures often are below approx 15C and thymol is not very effective..

I do not like using insecticides but sometimes it is the lesser evil.



The smell of thymol on a warm evening can be quite therapeutic (to me at least).. although an irrelevance.

Vape No. 6: 24h count = 532

The good news is H2 just got 13 on the 24h count. H3 is under control. And H4 had <40 at last count.
