Anything that kills plants, or insects, quickly will likely bare the potential to kill reptiles, fish and mammals slowly over long periods of time. If you want to control invasive vegetation in your garden, I would recommend an aeroponic or hydroponic system instead.

Mulch, straw, hay, leaves... all mulch great and are weed control. If you wanna go a little cheaper and barebones, landscape fabric does the trick.
