Yes, they will live at those temps, but will be basically hybernating, so your colony will not be growing through the whole season and slow things down, this will be discouraging just starting out especially. Maybe a seed starting heat mat.I'm considering meal worm farming but I have serious doubts the wife will allow me to do this in the house. The garage is a maybe. However, my garage in the winter will average between 40f and 60f degrees. Would it be recommended to heat the container I keep them in? If so... how? thanks...
