Is there a product I can use to control large caterpillars from my new guinea impatiens?
Some were the size of your small finger, which made them relatively easy to spot! Some were green, others were brown. Typically they have the two eye spots and a tail that sticks up. Not overly striped, but the brown ones were bit more striped than the green (but seemed to be the same generally).
Yates Success Ultra will control caterpillars on ornamental plants. Once they nibble the foliage, they ingest the chemical and stop feeding immediately. They will take three days to die.
