Cool. I would use a mild bleach solution to clean it out and leave it in your hot Texas sun to cook any other little critters that may lurk about.
If it were my cage, I would take out those shelves and put in a potted plant like a ficus (Home Depot sells them for $40) or cut the shelves so they could hold some plants like pothos or whatever. You can string some vines or the tomoto vine wire that other threads talk about. Place UVB and heat source on top and viola!
How tall is that? It looks to be about 6 feet or so and 2 feet wide?
Also, replace your bottom with something waterproof to help with your dripper and water from the plants and make it flush or add a drain.
