Carnivorous Plants?

[RandomGemini]

Has anyone grown these indoors?

I have some sort of crazy gnat problem in my kitchen. I have no idea where these things have come from and I am tearing apart my kitchen today to figure out just what in the heck is going on, but I am considering picking up a couple of flytraps, pitcher plants or possibly a sundew (available at my friendly, neighborhood hardware store) to help with the problem. Thing is, I'm reading that these do best if allowed to grow outdoors and it gets too cold here for them to survive the winters. It's usually below 30 degrees through January and February. Anyone had good success keeping these alive as indoor only plants in the winter?

Also, any other ideas on how best to provide care for these would be appreciated! Thank you much OB!
