I've fed them to aquarium fish with no problems at all. They're not
exposed to fish diseases unless you also have "sick" fish in the same
water with them. I've also used mosquito larvae I found in standing
water outside.

That is not a correct assumption Koi-Lo. There are plenty of parasites and
viral diseases that use an indirect transmission route through multiple and
radically different hosts. Just because the mosquito larva themselves have
not had direct contact with an ill fish does not mean they are perfectly
safe.
