Ok so about growing a venus flytrap?

Ok so I know this much so im not too stupid. Get a pot and fill it 1/3 with sand or pebbles to be immersed in water. Fill the rest up with peat moss--never soil and put the plant in. Keep it damp--not wet. Feed it bugs every ten days at max. In the winter it can be put in the fridge to create a good winter temp. I have a few questions. Can I feed the plant crickets from the petstore? And can I put a plastic bag over the plant to help raise the humidity? What else do I need to know? Please, I want answers from people who know what theyre talking about, not people who think "Oh, they eat flies, right?". Thanks.
