Take the enclosure outside and do it. Do not spray directlly on the animal and follow all instructions to a tee. Pam is no joke and can kill a snake if your not careful. Ive seen it happen. A local guy here sprayed a tub in his collection and put the sbake backnin right away before letting it dry and by the next morbing the snake was so neuro it had lost all control over all motor skills. It was really bad. Needless to say the snake didnt make it.
