Has anyone have any experience with using this varroa mite treatment?
Im thinking of using it as I make up my nucs.
Does anyone know if this treatment has been approved for use in Canada?
Thx
did you treat once or three times, threads on beesource have said that you have to treat three times (once a week?) to kill the mites as it doesn't kill the mites in the capped cells.
A treatment like this, where it has a treatment period of only a few days would only work in a broodless situation. I can manage into that treatment situation while making up Nucs.
The question I have is, does it actually kill mites?
I used it on 200 splits this summer right at the brood break that i get with a cell and it knocked them in the head. On my hives with brood not that great of kill. Any hives i make with cells i will use it again
thats exactly my plan too swarm_trapper!
It has been suggested that this treatment is very easy on the bees and queens, it is very hard on mites, but its only a few day treatment. I plan on making a bunch of nucs which will be queened by cells. During that broodless break, my plan is to treat them with Hop Guard. If the treatment kills the mites, I should have mite free nucs as the queen starts laying.
did you do any pre and post mite counts on your splits
Ian i did do alcohol washes before and after, The before was around 15-20 in a roll the after was 0-1 mites (this is per 300 bees) These bees were actually so clean that i didn't treat them before my pepper crop every thing else needed treatment. The way i treated them was i hit them at i think day 19 from when i put the cell in that way there was hardly any brood, then i think i hit them one more time 7 days later when doing checkbacks. I don't know if the second time was necessary or not. But it didnt hurt my queen takes at all! And in my splits i just used on strip per hive so it wasnt that pricy, doing it twice cost 1.20 a hive.
Wild branch i hit some of my older bees with hop guard 3 times and it only took the levels down from a 20 to a 7 so it still wasn't clean enough in my book. Had to hit them with a thymol clean up.
That sounds like a really effective program Nick. I have used oxalic at the 20 day mark with good success though I was concerned that a nuc with a newly mated queen just getting started may be slowed down as there is research out there showing that oxalic use can slow brood production a bit. This well may be an excellant way to use Hopguard.
Yes I have used Oxalic acid also and I am always very worried about my queen health when using Oxalic or any other type of acid treatment. Hop Guard may be an excellent fit for this type of management option.
Thank you swarm_trapper with your mite wash counts. 5-6% mite load starting, 0%-.3% mite load after treatment is an excellent knock down. In fact I wouldnt even call that a knock down, Id call that a complete treatment.
Im going to look into this treatment further.
Mike. Treated 3X. There was brood as it was in the peak of summer flow. From this discussion, maybe I should have used it on the nucs I make up with cells in the spring.
Hop guard is almost a two person job one guy to open and close and smoke, and one to put in the strips. I just get a small dish pan and dump 2 packets in and the juice and pull them out of there. The hop guard did not hurt the virgins i was a bit worried that it might, but i got the best take of the year on those bees so i was happy.
Unfortunately I an, it is not registered in Canada and will likely take at least 2 more years before it is registered here, if ever it does get registered here.
Treatment in the winterin shed would be very nice and the right time to apply seeing as the bees would be broodless. This could work well with a fall treatment of formic acid, which in my experience slows the mites down but gives such variable results. Kinda like a one, two punch cmbination.

I've used hop guard for 2 seasons now with good success. My method is 3 treatments about 7 days apart. I use 2 strips per bood box with each treatment. Most of the hives will shread the strips and have most of it removed from the hive. In my experiance the mite count drops big time the first 2 times leaving very few mites. The 3rd doesn't really change much ( maybe see a mite ) with an alcohol shake. I've had hives with high mite loads that were dwindling fast and been able to turn them around and successfully winter them after hop guard treatments in summer. I don't think placing the strips would help much in winter as the bees need to come into contact for it to work properly. As for ease of use, I find it pretty simple. Place 2 strips in bottom brood box about 2 or 3 frames apart and same on the upper brood box. It is kind of messy and sometimes the bees will attack the strip and hands that have the "juice" on them although not always. This small "attack" is usually limited to the hive and I haven't seen them act aggressivly other than that. I consider it expensive at 3 treatments x4 strips per hive =12 strips for the season. I bag of Hop Guard has 50 strips at about $30. When you do the math it ain't cheap but in my experience it has worked very well. That said, it's too much money and I won't be using it next year for my 50 or so hives.
Well, I'll tell you this, I dont plan on making a trip to get some,
when it is registered in Canada Ill be the first in line to get some.
if thats what you mean
At our up coming beekeepers association meeting they have booked a speaker from Health Canada talking on illegal product imports and repercussions. Should be interesting
I have heard that the strips kill brood if placed as directed, but don't when laid across the top bars. Thats, all I've heard, and i've never used them.
I've not experienced any brood loss. I've been very happy with how well Hopguard works and would be great for some with 4 or 5 hives. It's too expensive if you have very many hives though.
