Sap on Nepenthes?


Question
I've noticed that my N. Sanguinea is oozing a sticky substance from its leaves.  Not a lot, but but there are a few drops on the shelf it sits on. and tiny amounts seem to seep out of tiny pores on the underneaths of the leaves.  Is this normal?  This plant seems to be the healthiest of all my Nepenthes, but I've never noticed this issue before and none of my other plants have ever done this.  The plant lives inside and gets most of it's light from a full-spectrum fluorescent bulb as well as some very dim daylight from outside.
Thank you!

Answer
Hi Laura,

Some Nepenthes do exude nectar from the leaves to help attract ants.  Usually you see it a little round dots that are shiny.  The other thing that can cause this is insect pests.  Get a hand lens and look under the leaves and the stems.  Insect pests such as scale and thrips cause this too.  Scale insects look like brown/white bumps and thrips are tiny narrow insects.  Both suck sap.  If you see these, the best cure is a systemic insecticide containing imidacloprid.  Many of the Bayer products have this.  You would need to spray the plant outside, then bring it back in after it was dry.  You might need to repeat two weeks later, especially for scale.

Good Growing!
