I am looking for some guidance on re-utilizing frames from dead-outs that likely died from varroosis and DWV.
I recognize that I am unable to identify the viral pathogens "for sure" as DWV, and that other pathogens, viral or otherwise, certainly would require that I destroy or radiate the equipment- and it would be likely the safest practice to do so with any dead out- but I am curious to know if others go to that extent when the fatal pathogens are most likely DWV (and also, I would guess, Nosema in some hives).
How long does DWV remain viable off its host?
In the past, I've scraped everything clean, torched supers/brood boxes, and soaked wooden ware and plastic foundation in a bleach solution. This was the advice of Judy Chen when I asked her about CBPV, which I had a number of years ago and which partly spread through an apiary.
But is that required also for DWV? Destroy everything each time I see it just to be on the safe side? I'll admit- I currently only do this for dead out frames with dead capped brood-as it seems like an obvious source for viable viruses, if there are any. But in fact, I don't know- being that the virus is present in most bees at some level anyway- what is good practice here?
Thanks for any advice on this-I am curious to hear what the science is, and also what others generally do.
