Carnivorous Plants/something eating pitcher plant

QUESTION: I have noticed something is eating on my Purple Pitcher Plant.  At first I noticed what appeared to be white webbing type stuff in a new pitcher.  I thought it was fungus so I sprayed it with the recommended spray but now I see holes in another fairly new pitcher and very fine webs.  I will try to attatch a photo.


This is most likely a caterpillar of some kind, or a slug or snail.  If you have any other plants you have to protect from slugs or snails, that is your most likely suspect.  If not, you may have some roaming caterpillars that are taking an occasional bite out of the plants.

If can see the planter is on the ground, so mollusks are a strong possibility.  If it seems likely, bait for them or use appropriate barriers.  For insects, many insecticides will do the job.  A systemic like Bayer 3 in 1 would work, or a product containing Spinosad would be very good for caterpillars.

Good Growing!

QUESTION: Thanks for your quick response.  There doesn't seem to be any damage to the sundew or flytrap that share the tray.

Hi Pat,

I rarely see slug damage here in the Northwest on Venus Flytraps or Sundews.  They love Sarracenia, with purpurea and oreophila being their top targets.  This is from last spring:

Good Growing!

No terrariums. No myths. No nonsense.
Just the straight facts from guys who grow and propagate

Our focus is to help help growers diagnose a specific plant problem and offer solutions. For example:
  • Why is my sundew not producing dew?
  • Is now a good time to divide my Sarracenia?
  • Why are the traps turning black?
  • What's a good substitute for perlite?
  • Why didn't my seeds germinate?
  • How do you deal with pests?
  • Can you identify this carnivorous plant for me?
We no longer answer general, how-to questions that are already posted on our website or demonstrated in our DVDs. For general plant care, please read our care guides:
