keep the inside a building of some sort. Feed them meat scraps or even dog food. Keep them warm at about 70-80degrees. keep them at about 50 percent humidity. they can take flight at about 80bdegrees if not kept semi moist. They need a pupating area----cardboard,cotton batting, styrofoam. Keep them well ventilated and keep covered with fine mesh as well u dont want any other bugs in there. I have found that they can crawl up plastic tubs so go with a glass aquarium that can fit a nice wt deer or a deep chest freezer. i can help you with a few as well. they are alot of work for trying to do ur own euros.
