What are the bags of caterpillars that form in the crotch of branches on my cherry tree?
The Eastern Tent Caterpillar is one of our earliest insect pests, hatching in early April. The caterpillars eat the foliage of cherry and plum trees while building ugly, web-like nests. They can easily be controlled with Thuricide, a biological insecticide. Spray the foliage of the tree and the caterpillars will ingest the thuricide (always follow label directions). See our staff for guidance.
