Hello amir9696, depending on your location, you can grow them outdoors, but if your location is like mine where we get mild winter conditions but still gets cold between 20F to 50F, I just grow my Nepenthes indoors, and my Sarrancenias stays outdoors year round. Sarracenias need that cold spell, and they just look ratty during winter as they go dormant, but returns vigor when temps warm up again. I have to keep both plants in standing water here, our humidity gets so low during our long dry months that lasts 6 to 7 months no rain.
If you have good outdoor conditions, with good humidity levels and full sun, you can certainly grow your Nepenthes outdoors. Just try to identify if your Nepenthes is the highland or lowland variety. See this link, it has good info about the Nepenthes:

Oops, did not see right away that your carnivore is a Sarracenia, so grow it outdoors and always in standing water even as it gets dormant during the cold season.
