My husband built a Mason bees house and it is almost filled to capacity! So excited about this. Question...what do we do with the full parchment rolls? Just leave them in the bee house all winter outside? Or pull them out of there drill holes and put the parchment rolls in a Tupperware container and store them in a cool, dry place until spring?
I think what is generally done is they are taken out, placed in a paper bag or cardboard box in the fridge (you want something breathable not a sealed container), then after all threat of frost has passed they are put out to hatch. This is to mitigate some of those early warm ups in the spring that are followed by a cold snap...that unpredictable spring weather can be devastating on the little guys! Another thing to do would be to put the bee house in a spot that stays cold longer in the spring (i.e. a frost pocket, north facing slope, etc.), you don't want them waking up too early is the main idea.
Check on YouTube for the mason bee videos. There are a bunch of them and lots of info. It seems best to take out the cocoons, get rid of any mites, wash and dry then them store them in the fridge in a container that has ventilation and moisture. Then you can clack out your tubes...put in new parchment and have it all ready for spring when they hatch.
When it is used for evil, then watch out! When it is used for good, then things are much nicer. Like this tiny ad:
