Just continue to monitor for any signs of respiratory distress (aromatic compounds in the oils could potentially damage lungs) and just general signs of something not being right (laying completely flat on the ground head and all, lethargic, refuses next meal, etc.). I don't use smelly stuff at all in my house because I don't want to breathe it in or come into direct contact with it and I would not want that crap on my snakes either, too many artificial chemicals that could have who knows what kind of effect on a living thing's tissues.
