ive had the same problem, just go to your favorite department store and buy a plastic storage shelf, if you dont have one laying around. just put the legs in water and the ants wont be able to get in, also just add some vasaline on the light wires so they dont climb up on those. this worked very well for me, but ive heard they dont mess with the chameleons that much but pick up dead bugs. but i didnt like them in there and this solved the problem
