But if they have been exposed to pesticides they are more than likely dead, or looking very bad.
I would think that most moths should be OK. One kind to watch out for would be any with bright, contrasting colors. Contrasting oranges, reds, whites and blacks often mean that the animal has strong chemical defenses, so it could make your geckos sick.
Fireflies and ladybugs have that kind of coloration, and they are real bad choices as herp food.
