Firstly I have a working scanner and can do what is needed. PM me for an Email addy.
Heather, sadly pretty much the answer is yes it is useless.
I gave my recipe a few pages back and my rationale, and must add mine was given to me by arguably the most successful bee farmer in the UK. It was tried and tested by him over many years and I am not going to say more on that.
Trapping pollen is fine but and I will admit to this, disease is here an ISSUE. If you want to spread chalk brood through your hives this is a prime way to do it.
Irridated pollen is the way to go by reason of being disease free and also it avoids stressing colonies by trapping.
I have, in my neighbours garden a willow with catkins on it already. so as the idiots will argue why use pollen patties? Because, a, it is miles from my bees and b, it is peeing with rain and they canna fly even if they wanted to.
I work on the KISS principle but at times it is really hard work...lol (Keep It Simple Stupid)
