    Default Formic solution absorbed into "soil moist" granules??

    Anyone try this as a way to keep some FA fumes in the hive? I soaked some last year and it takes a lot of formic solution. I never got around to using it though so I am going to try it again.
    I've been using DIY FA with meat pads but maybe this could be easier?
    Any thoughts?
    Thanks

    I have not tried this, and I have not used FA treatment. Do the granules release the same amount of FA over the same period of time, and is that an important factor in FA treatment?

    Have you seen this:

    formic acid fumigator and they do not stay in the hive long, 24 hours tops.

    I will have to test some saturated granules & get back with results.
    It is my understanding that the FA vapor has to be present in at least a 50% concentration long enough to pass through brood capping. This kills the male mite that is produced once a female enters an open brood cell. After the cell she is in is capped the first egg she lays hatches a male mite. He then mates with the females that hatch from subsequent eggs that are laid in the cell.
    The male mite does not emerge from brood as he dies after mating. The male mite also has a very this exoskeleton and is easily killed by the FA vapor that passes through the capped brood cells.
    The other method targets the phoretic mites only so it has to be applied 3X every 6 days. Again this is my understanding. I am not a scientists etc.

    Have I seen what? A bunch of dead bees, DWV bees & varroa? Hell yes I have.
    Oh, you mean the study/photos. No but thanks for these. I am not looking to use fume boards. Too much equipment & trouble.
    So far I like my pad method but there is always room for improvement.
