microworm cultures going bad in winter??

Hi guys

Started a new culture over a week ago and something seems to be going very very wrong! I prepare the oats, add the yeast and add some worms from one of my old cultures but the next day the worms i added seem to dry up for some reason and feels rubbery. A few days back i started a few more cultures and the exact same thing happend again! Could this be because of the cold? Although my cultures are kept inside.

Anyone have any idea what could be going wrong??
My babies need food!

 

Make sure to wet the culture with a sprinkle of water. I have a spray bottle for when I start a new culture, just spraying them lightly after adding the yeast.
HTH.
