I'm willing to try greenhousing if it's not to pricy to put in place
I just finished reading Mike Oehler's
Earth Sheltered Solar Greenhouse Book and thoroughly recommend it.
It's quite a fun and fascinating read, plus I really enjoy Mike's style of writing.
In it, he teaches a method of building which can be not only cheap to install, but free to operate year-round by using gravity and the natural warmth of the earth combined with storing thermal inertia from the sun.
If you could find stout trees to harvest and/or free lumber to use, along with something like used sliding glass doors for glazing, it could even be free to build.

We do use an aquarium heater in a vacuum insulated dog bowl, to keep water unfrozen for the chickens.
Another option might be a chicken water deicer. I was able to keep my birds' water unfrozen when it was 10F outside:
63F water a few minutes later:
I also think that a seedling heat mat might be able to achieve something similar, and some of the fancier ones even have a probe thermometer which could be put inside the bug container.
Bury it, or combine it with some form of insulation (like straw or hay, maybe akin to a
Haybox Cooker) and you've likely got a really nice space for some bugs or worms.
Heck, I think I might have to give this a try now...
