What role does burlap around trees play in preventing spongy moths?

Wrapping burlap around trees serves as an effective physical barrier designed to trap caterpillars. When spongy moths (formerly known as gypsy moths) are in their caterpillar stage, they often climb trees to feed on the leaves. By positioning burlap bands around the trunk of the tree, the caterpillars can become ensnared in the folds of the burlap as they attempt to ascend. This method helps reduce the population of these pests by preventing them from causing further damage to the foliage of the trees.

In contrast, burlap does not attract spongy moths or provide a hiding spot for them; rather, it creates a deterrent. Additionally, burlap does not contribute to enhancing tree growth, as it is primarily a management tool for pest control in this context.
