Parasites become an issue when in captivity due to strees largely. When an animal is stressed, parasites, which might normally not have too much of a detrimental effect normally, can kill the snakes. They can cause them to lose weight drastically among other things. If you want to go and worm your snakes often and pay for the vet visits, that is your choice. Earthworms and pinky mice are good feeders. You can always scent the food items with salamanders to make them appeal to the snake.
