Apibioxal Spring treatment

[Lincbee]

Having a clear out today I’ve found some apibioxal with a use by of April 2022, now there’s enough to do my hives twice so I’m thinking of treating twice 5 days apart. My question is would this do any harm to the bees this time of year? They were last treated in November via the vaporiser. Currently no supers on.

Thanks

Unlikely to be an issue AFAIK.

No problem if by sublimation.

Do they need treating?

If you did an autumn treatment keep it for this autumn.

Thanks everyone just didn’t want it to go to waste

Been a few decades since I studied Chemistry (as my Ancillary subject to Zoology at University) but looking at the chemical content of Apibioxal it is unlikely to chemically deteriorate (if kept dry) for years. and years.
