How to kill caterpillars on catalpa trees?

When catalpa trees are small, the caterpillars can be trimmed out (if they're young and gregarious) or handpicked and drown in a bucket of soapy water. Caterpillars that are parasitized should be left on the tree in order to allow the parasitoids to emerge. In the fall or early spring, after the caterpillars burrow into the soil to pupate and before the adult moths emerge, the soil around the tree can be tilled in an effort to destroy the pupae. When caterpillars first emerge and are small, products that contain Bt can be applied to the tree to kill them . Broad-spectrum insecticides should be avoided because of their detrimental impacts to natural enemies, which may make subsequent outbreaks worse.

Why do catalpa worms kill trees?

Repeated outbreaks of catalpa worms over multiple seasons or multiple outbreaks in one season where multiple generations occur may damage and kill catalpa trees, especially trees that are already weakened by stress or disease. Some trees are defoliated more frequently and may be more attractive to catalpa sphinxes than others. The reasons for this are unclear but may be tied to the genetics of individual trees. If an individual tree is continuously defoliated by catalpa worms and appears to be in decline, it may be best to remove and replace it with a catalpa with different genetics or with a different tree species altogether.
