would the weather have an impact on what you used? I installed on a very cold day in april last year (it was snowing) and I've wondered since if being wet in that cold was part of the reason my one hive never thrived, and died. (there were, granted, other reasons.... I'm just wondering if this was a contributing factor.) It just seems to me that maybe spraying them with liquid when it's really cold out might not help them much, but it was what "everyone" said to do.... :?
