Re: Pollen Patties shelf life?
I spoke to a Mann Lake Rep about a month ago and asked him about Protien Pattys which I got from a friend of mine. They were a year old, had not been stored in a cooler or freezer, but also not in a heated room nor where rodents had access to them. He said they would have a lower protien content than new ones due to their age, but they would still be good. The bees would still get some benefit from them.
I used 450 of them, some hives getting two. I was back thru my hives w/ the new patties and found no trace of the previou application after less than three weeks. So, whether they were as good as they could have been, the bees seemed to like them.
I can't really speak to your other questions.
