I have some pretty old 95% formic in the original poly bottles as
shipped by Duda Diesel. This stuff dates from before MAQS when I used
Nassenheider Evaporators from Germany. Searching online, I've come
across shelf lives from 12 months to unlimited if kept in sealed
original container. They can't all be right.
Does anyone on the list have reliable shelf life information? It's
still pretty cheap in bulk and I'm thinking I'd like to go back to a 65%
dilution on Dry-Loc pads as Paul described today. I've never used them
before. Any tips on bulk orders of Dry-Loc or other sources of formic?
Application time for Dry-Loc/25ml/65%?
I lost a few younger queens last year with MAQS full treatment in 70-80F
range. This year, I'm doing half-treatments and hoping for better
results. I used Apivar for the first time this spring after getting
horrendous April counts. And after December OA vapor, too! I've been
working on the same bottle of OA from the hardware store for 5 years.
Any shelf life to thing about there?
Thanks.
