Effective use of Oxalic Acid to suppress Varroa with Marion Ellis

With its high efficacy and low risk of contamination, many beekeepers are looking to use Oxalic Acid this year. We have brought in an expert panelist, Marion Ellis Ph.D, to better explain the use of Oxalic Acid. As an entomologist, his research into the effects of varroa and other parasites on honey bee colonies have given beekeepers insight into better hive management.

Please Note that some audio has feedback but the guest speaker's audio is clear.

Thank you for the responses and advice for the audio issue. This was a known issue after the recording was completed that could not be corrected, however, the main speaker can clearly be heard. We apologize for the sound quality but we deemed the information more important to post than scrapping due to quality of audio.

We have investigated the issue and will be corrected for future webinar recordings.

Audio was very clear for me. No microphone turned on and latest player loaded.

Thanks to Dr Ellis and BrushyMtnBee, very informative presentation.
Kind regards from a Chilean beekeeper

Fantastic information. Best out there yet. The measurements were exactly what I needed. Thank you.

[AhmadAbdi]

Great video, thanks a lot of sharing.

for the echo, Just try using a "headphone" and make sure you have echo cancellation on your microphone
You are hearing yourself back through your speakers I guess and so are we :)

Have these tests been done with formic acid?

Thanks for the great video. I really liked the presenter.

Please clarify which direction to hold the frame when looking for mite feces. If you are looking for feces on the upper surface of the brood cell (i.e., the ceiling) then would you not hold frame with the top bar "away" from you and the bottom bar toward you? You said the opposite at time stamp 9:10.

Audio was fine for me.
How many times can I treat with vapour in a month in the winter in s.e USA ? Treated 1 brood chamber 2 times 5 days apart.
Can I treat again. Had less mites with second treatment but still very
Thanks

I used the oxalic acid pipe method to treat my hives for varroa going into winter. I was told you can't over do it so I was little on the generous side. Now the hives I did this to are egg-less, broodless and apparently queenless. Has anyone encountered this before.
I had also experimented with adding brewers yeast, Soy flour, skim milk-powder and and egg to syrup to see how they would take it some time earlier as I had read this can be done to promote brood rearing and wanted to try it.

[BrushyMtnBeeFarm]

Again, we apologize for cutting the Q&A but please feel free to reach out to us with your questions.

Would this be a way to do a new package of bee's in the spring time?

[suekilgore]

Can I use the trickle method earlier? I've seen the evidence of mites. I'm near Atlanta GA. I know at the beginning you mentioned treating in mid August where you're at.

[rebeccaanderson]

Thank you for the information, I am sending an order in today. So let me get this straight, using the dribble method, do I need to use 5 mil per seam per broodbox or only add to the top so it will dribble down to the bottom box?

Or Pure Proof Grain Neutral Spirits 150 Proof, with 75.5% alcohol?

[aspencat]

sorry but the audio issue is "game breaking", 30 seconds and had to stop. Too bad since i am sure the info provided was good.

[CentralNH]

Turn mic off on your laptop and the echo is gone :)

[ALLofYOU]

Don't forget to add sea salt to the bee's diet
