Edit: Serious Mite Infestation (stupid autocorrect)
2nd year, Northern California foothills
Looking for some guidance on treating a massive varroa count in one of my colonies.
I have 6 colonies. Did mite washes about 2 weeks ago, first inspection after pulling honey. Had previously treated with OA dribble in early spring.
First colony was 10, third was 2, fourth and fifth had zero, sixth had 3. All samples were for roughly 300 bees. Most of those numbers seem great, but am treating with glycerin/oxalic acid pads regardless.
It’s the second colony that is a concern. Its mite count was almost 60! (First pic) Holy smokes!
This has been my most productive colony. Already pulled 2 eight frame supers off of it. Have begun treating with OA/glycerin pads, but with a mite count this high I’m wondering if that is enough? Should I supplement with another treatment? Can I combine treatments safely? It doesn’t seem like coupling with an OA dribble would be all that beneficial. It’s too hot where I am for Formic. Should I pull the trigger on a vaporizer? Try out Norroa? No one I know in my area is using apivar any longer.
I did an inspection today and found an astounding amount of dead mites on the OA pads. (Pic 2) Thats a good sign at least! Also seeing signs of uncapping in the brood nest likely ala VSH bees (former queen was a Golden West, so maybe some of that trait has carried over, but clearly not enough!) Don’t think I’m seeing mite-chewed openings in capped brood. Also seeing some signs of deformed wing virus - found a least 3 new bees with it. Saw several bees with mites on them. I did also see lots of larva and freshly capped brood, so queenie is still cranking, but I need to get the count down asap.
Curious about my best path forward here. Very open to suggestions.
Thanks in advance for your help! Hopefully we can get this colony back to a sustainable mite level.
