poison dart frog

Poison Dart frogs can they be non poisonous? I was told if you feed them cricket and non venomous bug they become non poisonous.

It is based on their diet

Hey,

Most dart frogs now are non-poisonous.
Non of the captive bred ones are poisonous since it is based on their diet.

Most dart frogs in captivity are fruit flies that are dusted with mineral and vitamin supplements.
If they do eat crickets, it would be pinhead ones. Very few dart frogs eat grown crickets.

I forgot were I read this, but there have been studies that have shown dart frogs stay poisonous for over a year, even after being fed non-poisonous insects.

Either way, poisonous or not, you don't want to handle the frogs at all due to harmful chemicals and oils on your hands that will either make your frog ill or kill them.
