Does anyone know what type worm this is and how to treat?
Worm Found on Jalapeno Plant
It is not a worm, it is a caterpillar, which will devour your plant. Pick it off with your fingers and throw it away - somewhere safe - or bin it. Now go back to your plant and check for others, if there is one there will be more. Make sure you look on the UNDER side of the leaves.
