Can i use three year old Foundation

[MuswellMetro]

just taken over some old equipement from my late father and foundwhat is for me a large quantity of brood foundation as i have only one hive ( 60 sheets of 5.6 and 30 sheet of 4.9 of foundation)..all sealed in their plastic bags

and 60 sheets of 5.6 super foundation

but i know that it is at least three years old..receipt from thornes feb 2006 and that my father sold his main hives in 2007

So Does foundation go off?

could i use it next year 2010? or the year after 2011?

How to i keep it sweet?

or do i just bin it?

No problem. You need not to do anything to them even if pals say that you should warm them up or what ever.

My brother gave me some brood foundation 5 years ago, I have no idea how long he had it stored for but I'm guessing a couple of years, anyway the bees have drawn it out without me doing anything to it.

In a fit of madness in 1982 I bought £200s worth of frames and foundation.
I still have a few frames left but used the last of the foundation this past season - 27 years old. Accepted by the bees without a quibble apart from one colony - see my thread "Wax abuse"
Your "young" foundation should pose no problems
