I live in a super old and drafty house, and in the wintertime I always wonder if my worms will survive. The worms reside in the colder half of my basement, but apparently it’s no problem for them: I was reading my Worm Briefs email subscription and there were testimonials of people that had worms surviving in both sub zero and above 100F temperatures! Check this out:
“I’ve had redworms survive Winnipeg winters for 2 years in a
row. Frost gets down past 6″ as I recall (could be wrong)
and we do get rather severe winter temperatures. This year we
have a thick blanket of snow but last year the sledders were
complaining quite a bit. Not sure of temperatures under the
snow but this evening we’re at -32 C (- 25.6 F) heading for
-34 C (-29.2 F). On top of that they’re giving us a wind chill
of -43 C (-45.4 F). I was very surprised to find my worms in
the lasagna bed last spring.”

I complain about temperatures in the teens, I have nothing to complain about! And on the other side of things:
“Just a quick comment re: temperatures that red worms can survive
in. I live in Adelaide, Australia and have my worm farm set
up in a large wooden crate with plenty of ventilation holes
and a moist towel over the top with a wooden lid over that.
We have recently had a couple of days where the temp has reached
45 C (113 F) and the worms appear to be ok and a couple of
years ago we had a heat wave when the daytime temp did not go
below 40 C (104 F) for 2 weeks and they still survived so as
you say they are pretty resilient.”

Wow! Chances are pretty good my worms will make it through the winter just fine…
