Although I agree that a varied diet is by far the best way to go not many people have the time or simply the desire to culture that many food items for our frogs. Also it should be clarified that not all tree frogs should be hung up in a mesh container and kept outside for the summer. There are alot of new members who may unknowingly put their Red Eyes outside in Palm Springs in the summer time to come back in a few hours and find dried up frog raisons instead. I would only suggest an outside enclosure for the very experienced frog owner or when someone is keeping frogs native to that particular area and again only under certain monitored conditions
