Question
I READ YOUR COMMENT ON HOW TO START CATALPA WORMS, BUT WHAT IS THE BEST WAY TO PROTECT THEM FROM WASP AND ANTS. IF THEY GO INTO THE GROUND IS HERBICIDES NOT A GOOD IDEA FOR SPRAYING AROUND THE TREES.

Answer
Herbicides will not kill insects. Herbicide are chemicals that kill plants (herbs).The chemical that kills insects are insecticides. insect--killer. insect--cide. It will not harm catalpa worms if you spray herbicides around the tree for weed control.
