If it does not affect the snake's eating habits then what's the problem?
Unless it makes the snake aggressive or overly shy.
If it does, then remove offending odors.
We are talking captive snakes here. It's not like the odors will affect defensive/alarm mechanisms by stunting or masking their smell.
A captive snake will adjust. If a big concern, introduce slowly, at a distance and mild odors first.
