Spongy (Gypsy) Moth Resources

The spongy moth (formerly known as the gypsy moth) has been a destructive forest and tree pest in Pennsylvania since 1932. Infestations are cyclic and regional, so different portions of the state may be affected during each cycle.

College Township will not have a spongy moth spraying program in 2023. However, College Township Council did authorize a budget allocation to help offset the contractual costs borne by Mount Nittany Conservancy for the spraying of properties on Mount Nittany, where there was some evidence of infestation.
