You can get all kinds of Drosera from: Tropical Carnivorous Plants

I'd think that Nepenthes would work very well too... I had to take it out of my frog tanks, because the pitchers were packed with dead fruit flies.

I agree, put a pair of frogs and the problem will be gone in no time, except then you'll have to start culturing the fungus gnats
