What is the best way to get rid of caterpillars?
To treat against caterpillars, you can spray any plants, trees, and shrubs that the caterpillars are eating with either Bonide Thuricide or Dipel Pro. Both products contain a non-toxic bacteria called Bacillus thuringiensis that destroys the stomach lining of the caterpillars. This causes the caterpillars to stop feeding immediately and helps prevent further damage to the plant. The caterpillar population will decline rapidly after enough of them have ingested the bacteria.
Bacillus thuringiensis is frequently used by organic gardeners for a variety of reasons. One specific reasons is that it will not harm beneficial insects such as Honey Bees and Lady Bugs. It is also safe to use on Fruits and Vegetables as well as ornamental trees and shrubs. Another added benefit is that it can be used on lawns and does not damage the grass.
