[Management] Most times, mechanical controls are effective. When young trees are heavily infested, the use of insecticides may be warranted. If a biological insecticide is used such as Bt (Bacillus thuringiensis), be sure to spray the entire foliage that is being affected. Caterpillars must eat a good amount of the treated foliage to be sickened. Bt is most effective for managing small, young larvae in the spring. If a contact insecticide is used, treat the larvae that congregated in the early morning. This way, you do not have to spray the entire tree, just the tents. In doing this, be sure that your pesticide is penetrating the tent. Making tears into the tents may be worthwhile before you spray. As the caterpillars mature, it is important that the surrounding foliage is also treated; the caterpillars disperse from the tent as food becomes scarce. As with all our chemical recommendations, be sure to read and follow the label. Be sure to distinguish label directions for fruiting, edible trees and ornamental trees.
Caterpillar While you like butterfly plants like passiflora, aristolochia or asclepias - no way you like what their babies-caterpillars do to them...
