How do I get rid of caterpillers on my snow bush shrub? - Knowledgebase Question

Black moths lay eggs on my snow bush shrubs and caterpillers emerge and eat the shrub down to the bare limbs. I have used diazinon which kills the caterpillers but then the black moths come back and the cycle starts again.
I've already taken out one of the bushes and replaced it with something else but hate to do that to all of them. What can I do to get rid of the black moths and caterpillers?

The Snowbush Spanworm (White Tip Black Moth) favors snowbush plants. If you don't enjoy the colorful, slinky inchworms & pretty moths, a spray solution of a spinosad containing insecticide product, or B.t. (Dipel or Thuricide) will control the larvae but won't stop the adults from laying eggs. If you can time it right, you can drape a row cover material over the shrub during the few weeks that the adults are laying eggs.
