I have had my colony going for about 8 months. They have been eating deer skulls in about 3 days. The last one I gave them took a little longer. I thought maybe because it was not as fresh as some of the others. I then gave them a coyote that had some freezer burn on the muzzle, they took almost a week to clean that. I even misted with ammonia and water although at first I think I had too much ammonia in the spray bottle. There are no signs of mites but seem to be less beetles than before. I did an advanced search and found a few posts about the beetles going through bust cycles. Does what I am experiencing sound like that? They are kept in an an aquarium in a chest freezer with 2 thermostat controlled ceramic heaters which keeps them between 79 and 81 degrees. The humidity varies between 15 and 25% as the freezer is in an unheated garage. I mist them at least twice a day to try to keep the humidity higher. I read on one post to increase the temp to close to 85 (aquarium is covered with screen so they cant fly out) so i did that and added a tub of water outside the aquarium to try to increase the humidity. Is there anything else I should do? Thanks for any input.
