I’m starting my first colony of Dubias. Very little on the market in Washington State, so thought I’d invest in it. They sit within a black 27 gallon storage container with a ZooMed heat mat underneath regulated by a Zilla temp controller set to 90 degrees F. That container is within a rolling 40 gallon storage container. The lid has nine holes of about 2 1/8 inches with mesh lined with a little idea of mine to test. I recently ran into a problem with fruit flies getting inside and their children!! Ugh!! We live in an orchard so it doesn’t surprise me that a few managed to enter. My idea was to use Opaque Leggings!! I lined the precut screens by cutting the legs off and turning them over the mesh with my arm much like a sock.Pictures below
