Answer: Caterpillars are among the most destructive palm pests, sometimes feeding on the fronds before they even emerge. Small infestations can be removed physically, but if the insects are in full force, they can do severe damage. The biopesticide Bacillus thuringenesis (sold as Dipel or Thuricide) is effective on a wide variety of caterpillars. Be sure to use according to label directions.
