more than 20, less than 100.
Bit of chalk brood, I wouldn't worry. Make a note and check how they progress in Spring.

Not quite the same query, but the inspection tray of one hive, as l mentioned in a previous post, is still showing a heavy mite drop after three applications of apilife var. I see instructions say l can do a fourth round if necessary.
My query concerns the mite drop. Quite a lot of mites are still moving around (l don't use sticky tray). Is this normal? I brush them all off into a nearby hedge and hope they can't find their way back, fingers crossed.

I've never used apilife var but if the numbers are still high, think about that fourth application.

I used apilife var a few years ago but I found it didn't work very well. It might not of been close enough to the cluster of bee's. I ended up using apivar instead.
In the first 3 days there was hundreds of mites on the inspection board.

As swarm has said maybe change tact and apply a different treatment.

Thank you all for your replies re Apilife Var. I find it very effective, especially given the mite drop in one colony. Does anyone have any thoughts about the mites that are obviously still alive on the inspection tray? Will they die eventually or can they crawl back into the hive?

I think that's the idea of using something sticky on your inspection boards.
I've seen varroa still moving and walking around I prosume they can crawl back into the hive and possibly attach back onto the bees.
I don't use vasiline but I just wash my varroa boards of regularly.

One way to combat this would to have the inspection board under the floor, ie
Don't slot it back in place but rest it as far away from the floor as pos.

Apilife Var doesn't want to be close to the cluster. You put it in the corners and it works by the vapours spreading around the hive. Apivar works by contact so needs to be closer.

I've used both in the past and both have been effective. I prefer the Apivar though as you can keep it in later in the autumn if necessary, and it's relatively clean. Apilife Var is more temperature dependent so may not work if autumn comes in abruptly. My bees propolised the Apilife Var wafers to the frames and it was a pain to scrape off.

Thats what I did, I put it in the corners maybe the temp wasn't consistent enough when I was using it.
Hence me changing to apivar.

Too many - but not nearly enough

Not really - if you're doing a mite count using the calculator you want to count the natural mortalities, not the live ones who happen to drop.

The colony l am monitoring closely is in my garden, so l inspect the tray morning and evening, cleaning the tray each time. I don't do a calculated mite count, just observe a large drop or small/reducing drop. Obviously could not pay such constant attention if l had many hives, or out apiaries or was a bee farmer.

Sticky trays are to help stop mites being blown away.
Dani, I have a colony who can do that with propolis. ;)
