Venus Fly Trap

Question

Can you tell me why the traps don’t close when an insect goes in it?

Answer 1

The insects may not be triggering the closing mechanism. There are three hairs inside each trap. For the trap to close, at least two of these three hairs must be triggered. Look carefully along the midrib of the leaf and you should be able to see the hairs. Additionally, the traps may become inactive if triggered too many times. A single trap can only open and close a couple of times before it will no longer function.
Also, these plants respond best in full sun or bright light (for at least 4 hrs a day), so make sure your is receiving adequate lighting.

Finally, VFT have a dormancy period of which they will not "eat" anything.
