just make sure anything that you cleaned with bleach is fully rinsed...especially water bowls.
i personally would nix the snake everyday for the first week if you want to be completely safe. just change the water daily.
Also, pay attention to vents and gaps leading into and out of the enclosure. you'll notice when using nix (depending on the severity of your situation) they will make a run for the vent holes but die before they get there
