My plant is a WIMP!

To those of you who were wondering how my carnivorous plant is helping to alleviate my fruit fly situation - it isn’t. That plant is like the cat that runs away from mice. I’ve had it for almost a month, and it hasn’t even caught one measly fly. I’ve even tried killing a few flies and placing them on the leaves of the plant - just to get the party started, so to speak. Still, nothing. Zilch. Nada. Maybe it’s just not hungry?
