Hi,
They are fairly easy to keep, just stick to these rules.
1 (and most important) always water with rain water or distilled water, not tap or bottled. stand the plant in around 1/2 inch of waterthroughout the summer and it's growing period.
2 Dont close the traps unless you are using live insects to do it.
3 Mist the plant daily with rain or distilled water.
4 Never use any kind of fertiliser on it
5 move it into a cool room with no direct sun untill it begins to grow again in the spring, keep it just moist at this time.
6 in the growing period give it as much sun as you can, if it gets plenty the inside of the traps will go red and it looks prettier :-)
If you follow these rules you will be fine.
