Hello thirdman!!! So you want to keep chameleons? Bugs loose in the house are part of the game. As long as you are keeping a chameleon, either one or one hundred, you will always have a bug or 2 or 10 get loose and you will always have some dead in the bug bins( very important to keep bug bins extremely clean). If you don't like bugs in the house, you'd be best with dubias and blatta lateralis as feeders but blattas WILL get out. Anything can get loose. Non climbing roaches in a feeding dish can get out, somehow nature takes control of itself. Flies are great chameleon food and cheap but they will get out also. A chameleon can knock a feeding dish over and there go the roaches. Something to prepare for. And the vaseline trick, some roaches can crawl right through it. If you put your chameleons outside for the summer, it's a good way to give your house a break for spring cleaning. But you will have escapees in the winter, make no mistake.
