How long can Apiguard be stored?

We’ve received a few queries about how long Apiguard can be stored.

Applying Apiguard

We know that, as long as the product has not been stored in hot conditions (in direct sun or above 30°C), Apiguard is stable for at least four years and probably up to six years in the sealed aluminium tray pack. We say three years’ stability on the label as this is the normal requirement but product dated June 2013 is perfectly OK to use this year.

However, if you are using a 3 kg tub, from which you have already used a large quantity, leaving a small residual amount of gel in the tub, this should be used with caution. If this is the case, you should try a little dose (25g) on a colony at a time to check the bees respond normally to it.  (If there is too much thymol and not enough liquid left, due to evaporation, then the product could be too powerful and will repel bees strongly, so try a little first and see what happens.) This should also be OK but we cannot guarantee used product past its shelf life.
