Hungry caterpillars can cause a lot of damage to your precious plants. Your best defense is to scout your landscape on a regular basis. Look over your plants carefully a couple of times a week. If you see chewing damage, try to find the critter responsible—it's probably a caterpillar.
When you find caterpillars on your plants, pluck them and squish them, or drop them in a jar of soapy water. If you have a severe infestation, you may need to spray. Use the least toxic products available first, and look for products that contain a bacterium called bacillus thuringiensis, or Bt.
