Worm Blankets?

It gets kind of chilly here in Pittsburgh, PA, and so does our basement on a 10 degree night. So what are the wormies to do? I wrote to my worm advisor, and he said they can survive fairly cold temps, but that the colder temps make them lose weight and not multiply as fast.

Hmmmm....sounds like a solution for a few other world problems to me....

Anyway, until someone invents worm blankets, worm comforters, or worm warmers (say that three times fast!), I'll just have to pray they know to stay burrowed down in the nice cozy peat, paper, and food mush!
