Be SURE you dilute the F10 properly. Wipe it dry. As long as everything is dry, your snake can go right back in. You shouldn't be smelling any chemical- if you are, something's wrong.
In my house, there's no such thing as "feeding day" or "cleaning day"- in other words, I have no inflexible 'schedules'. If you expect your snake to be nervous & refuse food after his home is cleaned, then just tidy it up for now, feed him, & don't deep clean until after he eats & has digested well enough to be handled. (I'd wait 2 days after his meal, at least.)
With my snakes, they wouldn't care- I can clean & feed right then- but BPs are often "special" about things like this.![]()
