Glad to know it finally caught something! Just give it time, Jared. Your plant is still acclimating to your current conditions. You just never know when an unsuspecting spider or other insect will happen to dip into the pitchers.
I saw this interesting link about caring for pitcher plants.

I also wanted to grow that particular type of Nepenthes, but I settled for a smaller one, since I do not have good humidity here and still trying to get to know it as well.
