Apivar Usage

Apivar has a two year shelf life from the date printed on the product. That expiration is for the sealed product. Once it is opened and the parent compound is exposed to oxygen, it starts to degrade. Unused strips will have much less anti-mite activity if stored for later use. All strips should be used after opening. If someone has need for 40 strips, they should either get four 10 packs and have no leftovers or get a 50 pack and throw away/use extra 10. 1 strip per 5 frames bees. Need to get into bees to see how many strips they need. Double deep hive jam packed full of bees needs 4 strips for treatment. 56 days is better than 42 days for treatment, but you need to make sure to remove strips before winter.
