I just got a soil without perlite because it was… cheaper…So why is perlite bad for insects to be on? The concern is really just impaction(which I've never seen happen, though I'd be careful with smaller chams). Certain fertilizers I can see, but even organic soil has fertilizers(doesn't mean they're necessarily dangerous)...
As for fertilizers. I’ve used organic fertilizers with my chameleons plants, actually caught one of them eating the soil with the fertilizer and He was completely fine. As long as it’s organic and states it in BOLD you should be fine. I usually read ingredients as well. So insects with organic fertilizers should be fine. If you want to be super safe get organic soil made for veggies/edible plants. If it’s edible than it shouldn’t pose any danger to the chameleons/insects either.
