And I'm 100% sure they do NOT... I've been breeding corns for 20 years and I have NEVER seen a baby corn take any kind of insect whatsoever. These rumors got started because in analyzing the stomach contents of wild corns insect parts were found. The reason for this finding is because some of the animals that corn snakes DO eat, like lizards or tree frogs or even rodents DO eat insects and so the snake will ingest whatever is in the stomach of their prey. Couple that with the fact that one of the most printed out corn snake care sheets is on Melissa Kaplans site where she states in there if your baby corn will not take pinky mice you may try insects. Melissa Kaplan has VERY little if ANY experience with corn snakes. And despite the fact that MANY MANY prominent corn snake breeders have repeatedly asked her to change her care sheet, she has refused to do so.
Not only do baby corn snakes NOT eat insects voluntarily, but the hard chitinous exoskeleton may even be injurious and cause impaction.
Please do NOT feed insects to your corn snakes.
