Hello All,
The solution is a high percent sugar/fructose solution so even in winter
has not been problematic. The first person to recommend oxalic to me was
Medhat in Canada. He suggested as a clean up after treatments like apilife
var & apiguard and even formic acid.
The problem with OA from the research I have done is keeping the hive below
varroa threshold until the broodless period.
The second problem is figuring the exact kill you got is hard as many times
it takes a couple weeks for varroa to die.\
With hard chemicals you stick a strip in ( when still working) and you get
thousands of dead varroa the next day. With OA you may only find a couple
hundred on the sticky board.
Many beekeepers are going to OA alone. I believe you need to treat at least
once with another treatment in our area. Apilife var and apiguard have been
the most used treatments in our area. Very temp and correct spacing of
treatments dependent.
A commercial beekeeper in our area used apilife var last fall and for
whatever reason did not get a good kill. He had hives crashing in summer.
I believe that now many are using soft treatments you need to test test
test.
Feed stores can supply a ivomec measured sprayer used for spraying the
ivomec on cattle. I have been told the method works for spraying OA. I
caution I have never used the ivomec sprayer but the information comes from
a reliable source.
My ABJ and Randy Olivers article came today so plan to read. Friends have
said an excellent article on OA.
