Question: I have a pot of Lantanas. They are growing fine, but I noticed there are blue and black caterpillars on the stems and leaves. Any suggestions on how to remove them?
Answer: If they have a white dot they can sting. Otherwise, just hand pick them from your plant. Or use Bt (Dipel or Thuricde) a bacterium that acts as a stomach poison to caterpillars but won't harm people or pets.
