AzaMax will control caterpillars
AzaMax is a natural product with a broad spectrum of pest control and broad plant applications. AzaMax is an anti-feedant and insect growth regulator which control (kills) pests through starvation and growth disruption within two or three days. Therefore this product is used when the bugger is chomping on the foliage. Any of the sprayers can be used to apply AzaMax

Other Natural Insecticides
There are a number of effective natural insecticides made from materials such as chrysanthemum blossoms (pyrethrum) or neem oil soap. There is detailed information about these natural insecticides in Yardener’s Tool Shed. Go to the file called Natural Insecticides.
There are several natural insecticides that often kill caterpillars on contact, but then will create a bad taste for the caterpillar and make it go someplace else to munch. Neem Oil Soap, Hot Pepper Wax, and Garlic Barrier all have this potential repellent capability when applied properly on the tops and the bottoms of leaves of the target plant. The repelling effect will last for several weeks to a month depending on the weather conditions.
