Approximately how long do you wait before putting the snake back in the enclosure. An hour or upto even a day? Also, its unsafe to feed on treated substrate? What do you recommend if the snake won't feed in another enclosure? I'm currently raising a young BCC and would be nervous about feeding in another enclosure because of stress/regurge issues.

Maybe instead of treating substrate would it be enough to treat the cage itself and then make sure you are putting in clean substrate?
