I have a can in the snake room, but i'm too lazy to go grab it. Im pretty sure the directions say to wait 30 minutes to make sure any fumes are gone and that they spray is dry, I wait at least that, sometimes up to 45 or an hour. Generally I feed the snakes in a separate container (im lucky enough, mine dont care where they are when they eat) and by the time they're done I can safely put them back in their regular enclosures.
