I tried Drosera before, placed it outdoors in a bright but not direct sun area, in standing water, but still got toast by our excessive dry heat. So good access to sunlight, humidity and keeping it in standing water will make it thrive better. The glistening tentacles as the sun hits it, makes it so attractive to insects.
Indoors, I find it easier to grow Pinguiculas and fungus gnats really love them a lot. Just have to be careful when they go into their non-carnivore mode, to avoid risk of making them too wet.
