I know many use the thermal heat from bioactivity as the only heat for the Dubia, but I'm in Colorado. I'd like to see some bug room setups as I plan to start a dubia colony this weekend. CHE? Where do you place it? Do you use a lid? Does the heat melt the rubbermaid? Probably seem like dumb questions but I'd rather not do something that results in escapees or dead buggos.
