    I have some carnivorous plants that have been living outside in pots during the summer. Drosera capensis, red and alba, Drosera aliciae, Venus Fly Trap, and pitcher plants. The Venus Fly Trap hasn't thrived too well even in summer, its traps rot and turn brown, but the Droseras have been thriving and are fascinating and the red one has even thrown up three shoots of pink flowers. They do a great job of catching all the tiny pesky flies and gnats.

    I am wondering how to keep them alive in winter. Are they better off outside, where the climate is mild for the UK, in the South, or would they survive better on my kitchen windowsill, which doesn't get much light?

    @groundbeetle I have problems with Venus fly traps and they only last a few years with me.
    Venus fly traps will take a light frost and tend to die back a bit in winter.
    Drosera tend to be perennials and hide below the surface over the winter returning in spring, they also can self seed.
    Sarracenias are fairly hardy and their range in nature runs up to Alberta. Some people in the UK grow them as bog/marginal plants the pitchers may disappear, but they regrow from the tubers.
    Mine tend to go into a cold greenhouse overwinter, but I have left them outside some years and they were alright.
    In your case I would bring the Venus fly trap and Sundews inside and keep them in a cool room on a bright windowsill out of full sun, they can be allowed to dry out to damp rather than wet.
    Most pitcher plants will be fine in a sheltered outside spot.

      Thanks for the information. I am not sure, as they get a lot of light outside, and winters here are very mild, and I don't have any bright windowsills, they wouldn't get much light let alone sun. Maybe I will try bringing some of them indoors and letting some stay outside. I have read elsewhere too that they shouldn't be completely wet in winter as they can be in summer.

      Mine don't get watered over winter and in the cold greenhouse they slowly dry out.
      As you say you are in a mild area I'd leave them outside in a sheltered spot.
