How to Take Care of a Small Venus Fly Trap
Venus flytrap is a pretty plant. Pretty hungry. (carnivores image by Vladdy from

Venus flytraps are one of the easiest of the small family of carnivorous plants for indoor growing. They are endlessly fascinating to watch, and make a great school project for a child. Named for Venus, the goddess of love (who could have been considered a man-eater), and its hinged mouth that closes like the jaws of a trap, the Venus flytrap needs only light, warmth, water and bugs in order to thrive. All Venus flytraps need humidity to stay happy, and the smaller they are, the more they need moisture.

Things you need

  • Small Venus flytraps
  • Mini terrarium

  1. 1

    Buy a small terrarium to keep small Venus flytraps in a constantly humid environment. A mini terrarium resembles a large transparent egg, and often comes complete with soil and instructions.

  2. 2

    Nestle your tiny Venus flytraps into the soil of the terrarium, being careful not to damage the traps. Cover the terrarium and place it in a warm spot that receives about six hours of indirect sunlight per day.

  3. 3

    Give your small Venus flytrap small bugs to eat. Catch them around your house, and place them in the terrarium. Venus flytraps have evolved to catch their own prey without help, but you can place a small bug in its jaws if you want to. Slugs are also a good choice, since they are slow movers and unlikely to escape the trap.

  4. 4

    Keep an eye out for half-digested bugs, which can rot and damage the traps of your Venus flytrap. Nudge them carefully into the centre of the trap whenever you see this happening.

  5. 5

    Control mould growth, a common problem for Venus flytraps, since they must live in high humidity. If you notice fuzzy, white mould growing on stems, take the lid off the terrarium, and move it to a sunnier area for a few days. Sunlight kills mould better than fungicides.

Tips and warnings

  • Puncture the top of the terrarium, or leave uncovered to increase air circulation if your environment is naturally humid.
  • Do not add fertiliser to the potting soil where small Venus flytraps are planted. Their carnivorous qualities evolved as a response to growing in poor soils, and rich soil will kill them quickly.
