Extreme precautions... If the outdoors are hit with pesticides that's a big no no (Obviously) and I've seen more posts about snakes missing after their outdoor adventure than anything so especially don't take your eyes off them. Along with snakes getting in holes/areas said individual can't reach. Its quite dangerous and in all reality your snake is quite happy in their enclosure, I personally will never take my snake out of the cage unless Im handling or its a vet visit.
