How do I prevent catalpa worms?
Answer:
There are several ways you can reduce catalpa worms on your catalpa trees. University of Memphis Director of Landscape Joellen Dimond says you can till under the trees. She says you can also spray the young larvae with Bacillus Thuringiensis (Bt), an organic insecticide.
