At a loss on hive loss

I am uncertain why all of my bees died. Until I find out I will not keep bees this year.
Response – Even those individuals with more experience often cannot tell the reason for loss – and it is not necessarily the same for all colonies or beekeepers. We sometimes can eliminate one or more factors but then are still left with well it could be due to this or maybe to that, etc. Our bees are having a tough time of it – the reason for our survey is to document how many, probable why and what some individuals are seeking to do about reducing losses/improving success. We do not have the answers – it is discouraging to do what we consider the best and then to lose a colony or all of them. Trust you will seek to get back into bees at some point. Thanks for sharing.
