Hive Top Feeder, water evaporating? I bought a Hive top Feeder, but for some reason the water from my sugar syrup keeps evaporating and just leaving sugar. It wasnt so bad with the 1:1 ratio and when it was warm outside. Now that its becoming colder it's not doing so well with a 2:1? Any tips ? Edit: I meant to say a hive top feeder.
